Single-Family Rental

How is it rented?Average stay under 7 days counts as short-term.

Small Multifamily (2–4 units)

Sited on a leased lot in a park? We treat the purchase as the home only, with no land allocation. If you own the lot underneath it, email support@costsegsmart.com and we'll set the study up that way.

Total Square Footage * The full property square footage — we treat it all as rental-use. Use part of it personally? You can carve that out after checkout.

Your share of the lot (%) * From your deed, CC&Rs or TIC agreement, e.g. 25 if four homes share the lot equally

Number of guest rooms *

Bought or built? *

Bought a finished home or unit and got a closing statement? You bought it, even if it was brand new. Choose I had it built only if you owned the land and paid the contractors.

Purchase Price * Enter the contract sales price from your settlement statement or closing disclosure. Filled in from public records. Please check it against your closing statement and correct it if it differs.

Enter your build-out cost (what you spent improving the leased space) — not rent or a purchase price. Best documents to upload below: depreciation schedule, fixed-asset register, construction budget, AIA G702/G703, invoices, photos. Total hard + soft construction cost — everything you spent to build it, not counting the land. We'll ask for your builder's breakdown on the next screen; documented actual costs make a materially stronger study than our estimates.

Do you know what the lot cost?

Lot purchase price

No problem — we'll ask again when you send your cost breakdown. It doesn't change your deduction either way; land is reported separately from the building.

Total project cost: —

Do you have a cost breakdown from your builder? Using your contractor's actual cost ledger typically produces the most defensible study, because every classified dollar ties to a documented project cost instead of an estimated construction model. If you have one, we'll hold your study until it arrives rather than build the weaker version. Don't have one in a usable shape? Start from our Excel template — one line per item, what it was and what you paid; we assign the tax categories.

Who paid for the improvements? * This determines who owns the depreciable basis. If the landlord funded and owns the improvements, the deduction is theirs — so we confirm this up front.

I'm under contract — I haven't closed yet Order now and we'll build the study right after you close. Nothing is lost by the wait: your depreciation starts when the property is ready to rent.

When do you expect to close? * We'll ask for your settlement statement once you close. That's what sets your purchase price, the land split and your placed-in-service date.

When did you buy it? *

Use the closing date on your settlement statement or closing disclosure. From county record — please verify. Check it against your closing statement and change it if it differs.

When was it first ready to rent? *

The first day it was ready and available to rent. This can be earlier than your first tenant or guest. Bought before this year? Enter the date it was first ready to rent.

How did you acquire it? *

What tax year are you filing for? (prior-year property — optional) I've already filed my return for that year Lets your report include a Form 3115 §481(a) catch-up estimate. Your CPA confirms the final figure.

Number of Units

Did the purchase include furniture, fixtures & décor (FF&E)? Turnkey commercial purchases often convey FF&E (dining tables & chairs, bar stools, display fixtures, décor) — 7-year personal property. Pick the level that fits. If you have an itemized list or purchase allocation (Form 8594), choose “documented” and upload it after checkout — documented values are used instead of an estimate.

Documented FF&E value (optional) Enter the documented total if known, or upload an asset list / purchase allocation after checkout. Documented values are carved out as observed property; otherwise we use a conservative estimate for the level you chose (and hold the report for a quick review).

Is the building leased to a business that operates in it? For example a store, restaurant or office tenant. Skip this if you are not sure.

Who owns the store fixtures and build-out? Shelving, counters, signs and the tenant's own improvements. The lease usually says. A tenant's fixtures are not part of what you bought, so they are not in your study.

Have you made significant improvements or renovations to this property?

No Yes

About how much did you spend in total? *

Yes, that is right

Your best estimate is fine. If you have a cost list, you can break the total down below or upload it after checkout.

Was the work finished before the property was first ready and available for rent? * Ready and available for rent means placed in service. It can be earlier than the day someone moved in.

Yes, all of it No, it was done after the property was already in service Some before and some after Not sure

What year was the work finished? If it was finished over several years, choose the last one. To give a year for each project, list them below instead.

When did the renovation work start? (optional) The month work began can affect the bonus rate on the renovation. Leave blank if unsure.

Did the renovation remove or replace existing parts of the building? For example old flooring, cabinets, appliances or a roof that came with the property.

Yes No Not sure

What was removed or replaced? Tick all that apply.

You can also add project details after checkout.

List each project with the year it was finished. We work out the tax timing from the dates, so there is nothing for you to classify.

Improvement

Type

Cost

Year

Started (optional)

Qualified improvement property (§168(e)(6)) Interior work you had done to a nonresidential building that was already in service can be 15-year property instead of 39-year, which usually means a much bigger first-year deduction. It applies even if the work was done before the property was first ready and available for rent (placed in service) by you, as long as the building itself was already in use by someone. “No” and “Not sure” are real answers. An item you are unsure about will be held and asked, not assumed.

The building is nonresidential (39-year) property.

Yes No Not sure

The work was inside the existing building — no enlargement, no elevator or escalator, and nothing structural.

Yes No Not sure

The building was already in service — by anyone, including a previous owner — before this work began.

Yes No Not sure

Year the building was first placed in service (by anyone)

Month, if the same year as the work

I had this work done. Work a previous owner did, which came with the building, is not included.

Yes No Not sure

You own these improvements and will depreciate them. They are not a tenant’s property and not a landlord allowance written off over the lease.

Yes No Not sure

I certify these answers are correct. Answer every question Yes or No before you certify. While anything is “Not sure” the box stays off — we would rather ask you than record a claim you did not make.

Optional add-ons

Partial Asset Disposition Analysis (+$)

For qualifying renovations involving the removal or replacement of existing building components. Requires supporting documentation.

Was the property already rented out or in use by you when the old components were removed?

Can the tax return for the year of removal still be filed or superseded, including extensions?

Is the building in a general asset account (GAA)?

Were the removed components yours, not a tenant’s improvement?

Roughly how many components were removed?

Depreciation records for the building

One flat fee per building: these answers decide whether the study can be done, never its price. After checkout we collect the removed components, the replacement invoices and the depreciation history; the fee does not change. Ineligible after full review: the add-on is refunded in full.

Renovation Cost Segregation (+$)

Separate analysis of $100,000 to $1 million in property improvements, including identification of eligible accelerated depreciation.

Automatically included based on your renovation details.

24-hour rush (+$)

Your 24-hour turnaround begins once payment and all required documentation are received, weekends and holidays included. If we need anything before we can begin, we'll tell you. If we miss the deadline, we refund the rush fee.

In-person site visit (+$)

Travel included. We schedule within 1 business day; your study follows about one week after the visit.

Performed by an independent field data collector. Full refund of the site visit if you cancel before the visit. No refund for a no-show or no access on the scheduled day; the study then proceeds remotely.

In-person site visit available by quote for this property and location.

A site visit takes days to schedule, so it can't be combined with the 24-hour rush.

Three questions for your tax preparer

Most small farms have made none of these elections, and your tax preparer will know.

Has the farming business elected out of the limit on deducting business interest? (section 163(j)(7)(C))

Yes No Not sure

Has the taxpayer elected to deduct the costs of raising trees or vines right away, instead of adding them to what the trees cost? (section 263A)

Yes No Not sure

Has the taxpayer chosen the alternative depreciation system, which uses longer recovery periods, for this property? (section 168(g))

Yes No Not sure

Is any house on the farm rented short term, for stays under 30 days?

Yes No

Are there fruit or nut trees or vines on the farm?

None Almonds Something else

After you pay we will ask for the list of what is on the farm. Your draft comes back one to two business days after we have it.

Optional details — skip these for now or add them after checkout

Common elements — ownership Does your condominium declaration give you an ownership interest in the shared areas (pool, gym, parking, landscaping, roof deck), rather than only the right to use them? Most declarations do. If you own a share, part of what you paid is attributable to those assets and some of it may qualify for shorter recovery periods. Yes — I hold an undivided ownership interest in the common elements
No — I only have the right to use them
I’m not sure If you are not sure, leave it there and we will ask your CPA. We do not review the declaration as part of this study, so we cannot answer it for you.

Equipment inventory — the heart of a gym study Cardio machines, strength, racks, and free weights are removable 5/7-year property — the biggest tax lever in a fitness facility. Enter the approximate documented value per category (a total you can back up with an invoice / asset schedule). The mix tells us your facility type and activates the right flooring & improvements. Optional, but it's where most of the benefit is — add a detailed equipment schedule for maximum acceleration.

Facility features (check all present) A few features we can't read off the equipment list. We stay conservative unless you confirm them. Dedicated weightlifting / turf performance flooring
Indoor pool
Sauna / steam room
Commercial-grade HVAC / dehumidification upgrade

Community amenities (check all present) Shared amenities across the property — these are separable 5- and 15-year improvements the building shell doesn't capture, so they accelerate. Check what's on site; we stay conservative unless you confirm them. Package locker room / parcel lockers

Documented tenant-improvement buildout

Was equipment included in the purchase? Turnkey / practice purchases often include equipment (e.g. dental chairs & imaging, sterilizers, kitchen line, machinery). When it's part of the acquisition, it's reclassifiable 5/7-year personal property — we include it only with documentation.

Documented equipment value (optional) Enter the documented total if known, or upload the purchase-price allocation / equipment schedule / invoice after checkout. We carve it out as observed personal property — it never inflates the building estimate.

Property features (optional)

Pool, deck, garage, solar, etc. — check what applies and we'll capture those site improvements beyond the building shell. Optional. Swimming pool Deck / patio Is it attached to the house, or freestanding on the ground? Fencing Professional landscaping Garage Solar panel system Washer & dryer conveyed with the property How many separate laundry setups? (required for us to include it) A washer and dryer pair with the hookups serving them. A laundry sink or an unused rough-in doesn’t count. Most houses are 1. Low-voltage, AV & smart home Dedicated equipment serving the home — separate from the building’s own wiring. Counts are optional; give them if you know them and we’ll use yours instead of an estimate. Structured network cabling & patch rack Network drops (ports on the patch panel), if known Network equipment & Wi-Fi access points Access points, if known Distributed / whole-home audio Zones (rooms with speakers), if known Smart-home control system Wall touch panels, if known Home theater

Which best describes it? (required for us to include it) Display

Appliances included in the sale Just check what’s there — no need to know the wiring. Electric appliances have their own dedicated circuit, which is 5-year property we can capture. Gas ones don’t, so checking them tells us not to claim it. Electric range / oven Gas range / oven (no dedicated circuit) Dishwasher Garbage disposal Built-in microwave Refrigerator (built-in or on its own circuit) Electric clothes dryer Gas clothes dryer (no dedicated circuit) Clothes washer Specialty appliances Less common, and each has its own dedicated circuit — worth checking if you have them. Cooking appliances share a single 240V circuit, so checking more than one won’t double-count. Induction cooktop Double wall oven Warming drawer Built-in / undercounter wine refrigerator Beverage center or undercounter refrigerator drawer Dedicated ice maker (not the one in the fridge) A second dishwasher, in addition to the main one Site improvements present Check what’s on the lot. These are easy to miss and each one is a 15-year asset, so telling us is worth real money. If you have a survey, site plan, or appraisal, uploading it (below) lets us measure them precisely. Irrigation / sprinkler system Exterior or landscape lighting Retaining wall Storm drainage, French drain, or site grading Mailbox or other site accessories

Multifamily details A few unit-level details that materially affect the allocation. Optional — select / check what applies. Per-unit heating & cooling Ductless & packaged units (mini-splits, PTAC, window, through-wall) are removable equipment — 5-year property. Ducted systems (central or separate-per-unit) are part of the building — 27.5-year. We use the conservative treatment for ducted, mixed, or unsure. Kitchen & laundry appliances Refrigerators, ranges/ovens, dishwashers, microwaves, washers/dryers and disposals are 5-year personal property. We include them by default (they normally convey with the building) — tell us only if they don’t. Site features (check all present) Carport(s) Paved parking lot Detached structure (shed / laundry / maintenance / leasing office) Common laundry room

Car wash configuration A car wash's value is mostly equipment + site work. These details let us size the 5-year equipment accurately. Optional — enter what you know; documented equipment costs (below) always take precedence.

Tunnel length (ft)

Vacuum stalls

Pay stations / lanes

Dryers / blowers

Wash type Water reclamation / treatment system present Was wash equipment included in the purchase? Answer the “equipment included” question below — if documented, we book it as observed personal property; if not, we model it conservatively from these counts. Every car-wash study is reviewed before delivery during our calibration phase.

Gas station / fuel configuration A fuel site's value is mostly fuel equipment, tanks, and the canopy. These details let us size the short-life assets accurately. Optional, enter what you know; documented equipment or tank values (below) always take precedence.

Fuel dispensers (MPDs)

Fueling positions

Underground tanks

Canopy size (sq ft)

LED price signs

EV chargers (Level 2)

DC fast chargers

Attached car wash Convenience store on site Quick-serve / foodservice (QSR) Solar canopy / array

Is the fuel canopy freestanding (its own columns, separate from the building) or attached to the store? I don’t know Freestanding: on its own columns, separate from the building Attached to the store building This affects how the canopy is classified. If you are not sure, leave it on “I don’t know”.

Building is small-format / mostly fuel sales (may qualify for special 15-year treatment) We'll confirm eligibility with your CPA. This is not a tax determination.

Documented fuel equipment value ($) (optional) If you have a detailed equipment appraisal/allocation that supersedes counts.

Documented tank-system value ($) (optional) Documented tank-system value (e.g. from an environmental report).

Was fuel or store equipment included in the purchase? If documented, we book it as observed personal property; if not, we model it conservatively from these counts. Every gas-station study is reviewed before delivery during our calibration phase.

Mixed-use details A mixed-use building blends a commercial ground floor with residential above — these let us model each portion correctly. Optional; enter what you know. Ground-floor use

Commercial SF (ground floor)

Residential SF (upper floors)

# Residential units

Documented buildout / TI cost ($)

Tenant-improvement buildout was included & is documented A documented commercial buildout reclassifies a conservative share to short-life property. Without documentation we model the building only, conservatively.

Is this property 100% rental or business use?

Personal-use square footage The area you use personally and do not rent, out of your total square footage above. We depreciate only the rental-use portion.

ADU size — square feet The ADU's size, out of your total square footage above. Your study and price reflect only the ADU portion — not the whole property.

ADU bedrooms

ADU bathrooms

ADU has a kitchen or kitchenette ADU has a separate entrance

Separate systems or meters, if known

HVAC Electrical Plumbing

Outdoor amenities (check all present) Check anything on the property — these often qualify for accelerated (5- or 15-year) treatment. Hot tub / spa

Is it built-in or portable? (Built-in / in-ground spas are treated differently from portable ones.) Built-in / in-ground Portable / above-ground Not sure

Fire pit / outdoor fireplace Pergola / gazebo Outdoor kitchen Built-in grill

Has your tax professional determined how the building should be depreciated? Short-term rentals can be treated as residential (27.5-year) or nonresidential (39-year) buildings depending on how they're operated. Your CPA makes this call — tell us if they already have. If you're not sure, pick "Not determined yet" and we'll flag it for your CPA in the report. Residential — 27.5-year (per my tax professional) Nonresidential — 39-year (per my tax professional) Not determined yet

Have any invoices or receipts? Upload them (optional)

Optional, but worth it. Upload any invoices or receipts you have — renovations, appliances, flooring, equipment, or site work. No need to sort, label, or format anything; just drop them in. Documented actual costs are the strongest cost-seg evidence (stronger than our estimates), so they can increase your deduction and harden the study for audit. You can also add them after checkout.

Skip for now Upload files Type items manually

Were these included in the price you paid for the property? This is about where the cost sits, not when you paid: something bought separately can still have been in service on day one. If you're unsure, leave it — we'll ask before the study is finalized.

Before you check out

Last questions, answered.

What exactly do I get?

A 40+ page cost segregation report your CPA can use immediately. Includes:

Asset reclassification (5, 7, 15-year property)
Depreciation schedules
Detailed supporting documentation aligned with IRS guidance

This is the same type of report traditional firms deliver — just faster.

What documents help the study most?

All optional — but if you have them, these add the most detail, roughly in order:

Settlement statement — your Closing Disclosure, ALTA settlement statement, or HUD-1: the one-to-two page money summary from the title company. It confirms the closing date that sets your bonus-depreciation year, and the title, escrow, survey and recording charges on it are added to your depreciable basis.
Property photos — exterior, interior, kitchen, bathrooms, mechanicals.
Home inspection report (and seller disclosure, if you have one) — tells us your water heater, HVAC, roof and siding, so your study is more precise.
Floor plans or construction documents — verify square footage and interior components.
FF&E inventory (furnished / short-term rentals) — reclassifies furniture & equipment as 5-year property.

None of these are required — we complete your study from your intake details and public records, and cross-verify price, square footage and land against county assessor and ATTOM records. The settlement statement helps most: a documented land figure and closing date beat our modeled ones, and on new construction that usually moves in your favor. Upload anything you have, or send it after checkout — we update the report at no extra cost.

How accurate is this if I haven’t added everything yet?

You’ll get a complete report immediately, and you can:

Upload photos
Add details
Refine inputs

after checkout. We’ll update the report at no extra cost.

Most customers improve their results by adding details after.

Will my CPA actually accept this?

Yes — the report is structured to match IRS guidance and standard depreciation rules. Cost segregation follows MACRS classification rules and IRS frameworks like Revenue Procedure 87-56, which defines asset lives and depreciation treatment.

If your CPA has questions, we answer them in writing or on a call, and we correct anything that is wrong on our side at no charge. View a sample report →

What if my CPA doesn’t use it?

If your CPA can’t use the report, we’ll make it right. No one should pay for something they can’t use — that’s the CPA-Ready Guarantee.

How long does this take?

Most reports are delivered within 1–2 business days. Traditional firms typically take several weeks.

Is this actually legit?

Yes. Cost segregation is a widely used tax strategy that accelerates depreciation under IRS rules, moving assets into shorter recovery periods like 5, 7, and 15 years instead of 27.5 or 39 years.

This isn’t a loophole — it’s a classification method. See our IRS-aligned methodology →

Can I use this on a property I already own?

Yes. This is called a lookback study. You can:

Catch up missed depreciation
Take a large one-time deduction
Without amending past returns

What happens if I get audited?

Cost segregation is an IRS-recognized practice — the IRS publishes a Cost Segregation Audit Techniques Guide that examiners follow. Our reports are built to align with it: detailed asset breakdowns, MACRS classification, depreciation schedules, and supporting documentation.

Lifetime audit support, included: written answers to your CPA’s technical questions about our methodology, for the life of the study, no expiry. It does not include IRS representation. See the full audit-support scope →

What if my CPA wants something changed?

Free revisions for 12 months after first delivery, for the original scope of your study. If you send us a document we should have had, change a fact, or want the study rerun, we revise the report at no additional cost for 12 months after we first deliver it. If your licensed CPA, EA or tax attorney asks for a different classification, a clarification, or additional detail, the revision is free for 36 months after first delivery. After those periods, each revision round is a flat fee. If something is wrong on our side, the correction is free with no time limit. We work with your CPA directly: written answers, and a call or meeting when either of you asks. New renovation projects, additional properties and new placed-in-service events are new work, priced separately. Orders placed before November 17, 2026 keep the revision terms they were sold with: unlimited, free, and with no expiration.

If your CPA finds a problem with the report, send us what they flagged and we’ll revise it at no charge. If it still can’t be used, the CPA-Ready Guarantee refunds the study fee (terms).

Does this work for a short-term rental?

Yes — STRs are one of our most common use cases. Cost seg combined with the STR loophole (material participation + a 7-day average stay) can offset W-2 income, not just passive rental income.

STR reports include furniture, fixtures, and equipment (FF&E) breakdowns and apply a higher 5- and 7-year accelerated mix consistent with how STRs are actually used. See a sample STR report →

Do I need a site visit?

No. We use property data and your inputs to produce a detailed report. You can optionally upload photos to improve accuracy.
