Commercial Property Tax Reassessment Underwriting on Acquisitions
One of the most consequential line items in commercial real estate underwriting is real property taxes. When an investor acquires commercial real estate, local county assessors frequently reassess the property based on the newly recorded sale price. Underwriters model prospective post-sale property taxes rather than historical tax bills, ensuring the asset can support debt service under reset tax liabilities.

Tax reassessment rules vary by jurisdiction. Counties with biennial or point-of-sale reassessment triggers require customized financial modeling.
The Hazard of Underwriting Historical Property Taxes on Acquisitions
A catastrophic mistake in commercial real estate modeling is projecting historical property taxes into future acquisition pro formas. If an asset was owned by a legacy sponsor for 20 years, its assessed tax valuation may be $2,000,000, generating a $30,000 annual tax bill.
If a buyer purchases that asset for $8,000,000 in a point-of-sale reassessment jurisdiction, the county assessor will reset the tax roll to $8,000,000. At a 1.5% millage rate, the annual tax bill surges from $30,000 to $120,000—a $90,000 annual hit to Net Operating Income. Commercial loan underwriters identify this immediately and adjust the debt sizing model to the fully reassessed $120,000 tax burden.
How Lenders Size Tax Impound Reserve Escrows
Because municipal property tax liens take statutory first priority over commercial first mortgages (priming the lenders deed of trust), lenders mandate monthly tax impound accounts.
Borrowers must deposit 1/12th of the estimated annual property tax liability each month into an escrow account held by the loan servicer. Additionally, at closing, the lender collects a 2 to 3-month tax cushion reserve to ensure sufficient liquidity exists to pay county tax bills before statutory delinquency deadlines.
Frequently Answered Financing Questions
Verified answers to common borrower and broker inquiries regarding loan sizing, guidelines, and execution.
Do commercial mortgage lenders underwrite historical or reassessed property taxes?
For acquisitions, lenders underwrite reassessed property taxes calculated from the new purchase price and local millage rate, rather than the seller historical tax bill.
This prevents cash flow shortfalls when county assessors reset property values to the recorded purchase transaction amount following closing.
Submit Financing Scenario →Will lenders give credit for planned property tax assessment appeals?
No. Commercial lenders underwrite full statutory tax rates and will not credit anticipated tax reductions from pending assessment appeals until the county officially approves them.
Because tax appeal outcomes are uncertain and subject to county discretion, credit committees size debt conservatively based on existing or reset tax rolls.
