How much can a $750K single-family rental actually save in Year 1?

On a $750K purchase price with a 20% land allocation, the depreciable basis is $600,000. An engineering-based cost segregation study reclassifies about $120,000 (20% of basis) into 5-, 7-, and 15-year property — yielding roughly $44,400 in Year-1 federal tax savings at the 37% marginal bracket. Standard 27.5/39-year depreciation produces only $21,818 in the same year.
