Building Value %
Portion of purchase price allocated to depreciable building (not land). Defaults to 80% for SFR; land value varies by market.
Why Building Value % matters
A supported allocation to depreciable building affects the modeled depreciation deduction. The allocation must be grounded in the property's facts; a default percentage is only an input assumption, and passive-loss and other limits determine the actual tax effect.
How to check Building Value % before you rely on it
Start with the county assessor's split between land and improvements for the parcel, and ask your tax professional whether that allocation is supportable for your return or whether an appraisal or cost segregation is warranted. Do not use the default percentage in a filing. The allocation changes only the modeled depreciation, and whether that deduction reduces your tax this year depends on your own facts.

Where Building Value % shows up in TrueCap
Property fundamentals are the facts you enter or confirm about the building itself — price, units, bedrooms, square footage — and the analyzer keeps them separate from assumptions. They decide which benchmarks apply (a 3-bedroom rent benchmark, for example) and appear at the top of every results view and memo so the reader knows exactly what was analyzed.
