AI underwriting is software that reads a property's offering memorandum, rent roll and T-12, checks them against each other and the market, and builds the income model that an analyst would otherwise build by hand. It returns the model with its sources and names what it could not find. A person still decides.
What it does, step by step
- Reads the documents. Rents, expenses and lease terms are pulled from the files, not retyped.
- Ties them out. The rent roll is compared with the T-12, and both with the figures in the offering memorandum.
- Adds the market. Comparable sales and rents, zoning and the record on the property come from outside the package.
- Builds the model. Rent roll to stabilized net operating income, debt, returns and sensitivity grids, in a live Excel file.
- Names the gaps. A missing figure is shown as missing.
A worked example (hypothetical numbers)
An offering memorandum for a small apartment property shows net operating income of 468,000. The T-12 supports 412,000. The gap is 56,000, or 12.0% of the memorandum figure.
At a 6.0% cap rate, that gap is the difference between an indicated value of 7,800,000 and 6,866,667, a difference of 933,333. Nothing in the model is wrong yet. The underwriting simply shows the buyer which number the price rests on, and the rent roll and expense lines that explain the gap. These numbers are invented for illustration; they are not from a real deal.
What it measures for Titleman
Titleman's own run times, measured over the 30 days to 18 October 2026, give a median of about 58 minutes for an underwriting run. See how long AI underwriting takes for what moves that number.
What AI underwriting does not replace
- An investment decision. The output does not give a final price or a buy or sell verdict.
- A licensed appraisal. Where a value is shown, it is a value opinion, not an appraisal.
- Legal and environmental review. Title, leases and site condition still need specialists. A due diligence checklist shows what is left for people.
- A site visit. Condition and neighbors are seen on the ground.

Common questions
Is AI underwriting the same as an automated valuation model? No. An automated valuation model returns one estimated value. AI underwriting builds the whole analysis: rent roll to stabilized income, debt, returns and sensitivities, with the value as one output among many and every input traced to its source.
Does AI underwriting look at the property or the person? The property. It underwrites the collateral from the package that was sent: the offering memorandum, T-12 and rent roll checked against each other and the market. It does not run a credit check or assess a sponsor.
How long does AI underwriting take? Titleman measured a median of about 58 minutes for an underwriting run over the 30 days to 18 October 2026. That is a median, not a promise: some runs take longer, especially when a document is missing and the run has to ask for it.
Can I rely on the numbers without checking them? You should still check them. The point of the method is that every input shows its source and date and every result shows its formula, so checking is fast. Anything that could not be found is named as a gap, not filled in.
