AI and machine learning can help mortgage lenders process documents, verify borrower information, support risk assessment, and estimate property values. But an automated underwriting system (AUS) and an automated valuation model (AVM) do different jobs: an AUS assesses credit risk and loan eligibility, while an AVM estimates a property’s value. For title insurance, the documented workflow involves reviewing title evidence and resolving issues; the available sources do not establish how widely title insurers use AI or identify specific live systems.
What lender adoption figures actually show
Fannie Mae’s Q3 2023 Mortgage Lender Sentiment Survey found that 65% of surveyed lenders were familiar with AI or machine learning, and 30% had deployed the technology or were trial users. Another 55% anticipated broader rollout or starting trials within two years. These figures describe survey respondents in 2023—not all U.S. lenders, and not the market in 2026. The survey identified operational efficiency as a leading objective for adoption.
The survey also discussed application areas lenders viewed as priorities or possibilities. Those findings help show where mortgage AI may fit, but they should not be read as proof that every lender—or even a stated majority—has deployed a particular tool.
Where AI may fit in a mortgage loan file
Mortgage underwriting draws on borrower-provided records, third-party information, credit and property data, and lender rules. AI and other automation can support parts of that process, but the task being supported matters: organizing documents is not the same as deciding eligibility or estimating collateral value.

Application documents and borrower information
Software can be used to extract information from documents, classify records, compare figures across files, and flag inconsistencies for review. Fannie Mae’s 2023 survey identified borrower income and employment verification, along with documentation reconciliation and standardization, as mortgage AI development priorities. These are potential or recommended uses in the survey, not evidence that any one lender performs them with AI.
Credit risk and loan eligibility: the AUS role
An AUS evaluates an applicant’s credit risk and whether a loan is eligible for the relevant securitizer, insurer, or guarantor. The Consumer Financial Protection Bureau (CFPB) uses this definition in Regulation C, which governs Home Mortgage Disclosure Act reporting. In applicable reporting cases, a lender must report the name of the AUS used and the result it generated.
That reporting requirement does not require lenders to automate underwriting. The CFPB’s interpretation says that when an application is manually underwritten and no AUS is used, the relevant field is reported as not applicable. An AUS result is therefore a system’s credit-risk and eligibility assessment—not a property appraisal or a title-insurance decision.
Property value: the AVM role
An automated valuation model estimates a property’s value using data and a model. That estimate can inform a lending decision, but it answers a different question from an AUS: what may the collateral be worth, rather than whether the borrower and loan meet relevant credit and eligibility criteria.

Those survey references do not establish that a lender uses an AVM in a particular transaction or that an AVM replaces an appraisal.
Quality checks and compliance support
The survey also identified compliance management and discussed anomaly detection as possible areas for AI support. Such tools may help surface unusual patterns or organize checks, but the survey does not establish that AI makes binding legal determinations. A flag, score, or generated result still needs to be handled within the lender’s applicable review and control processes.
AUS, AVM, and title review answer different questions
| Workflow or system | Main question | What the cited sources establish |
|---|---|---|
| Automated underwriting system (AUS) | How does the application assess for credit risk and loan eligibility? | CFPB Regulation C defines the AUS role and provides for reporting the system and its result in applicable cases. It does not mandate AUS use. |
| Automated valuation model (AVM) | What is the estimated value of the property? | The interagency rule sets quality-control standards for covered AVM uses involving a consumer’s principal dwelling. |
| Title-insurance underwriting | What does the title evidence show, what issues need resolution, and what coverage can be committed or issued? | CFPB Regulation Z describes title-insurance services; Fannie Mae’s Selling Guide sets out title-insurance requirements and coverage topics for its lending context. These sources do not establish AI deployment rates at title insurers. |
The distinction is practical as well as regulatory: an automated value estimate cannot by itself establish borrower eligibility, and an AUS result does not establish that title is insurable.
Federal quality controls for covered AVM uses
Six agencies—the Office of the Comptroller of the Currency, Federal Reserve Board, Federal Deposit Insurance Corporation, National Credit Union Administration, CFPB, and Federal Housing Finance Agency—adopted quality-control standards for AVMs used in certain transactions involving the collateral value of a consumer’s principal dwelling. The FHFA’s rule page gives October 1, 2025, as the effective date.
For covered uses, institutions must adopt policies, practices, procedures, and control systems designed to:
- Ensure a high level of confidence in estimates.
- Protect against the manipulation of data.
- Seek to avoid conflicts of interest.
- Require random sample testing and reviews.
- Comply with applicable nondiscrimination laws.
This is a control baseline for covered AVM uses, not a blanket certification standard for every AI tool used in mortgage lending. Whether the rule applies depends on the transaction and use within its scope.
What title-insurance underwriting involves
Title-insurance underwriting concerns the evidence of ownership and other interests affecting a property, and the conditions under which coverage may be offered. The CFPB’s Regulation Z interpretation describes title-insurance services that include examining and evaluating title evidence under relevant law and underwriting principles, preparing a commitment that states proposed insured status and conditions, resolving underwriting issues, and preparing and issuing policies.
Fannie Mae’s Selling Guide has a dedicated title-insurance chapter covering lender requirements and insurance topics. That guide provides lending context; it does not document how many title insurers use AI or name particular title-insurance AI systems.
Possible automation points are not proof of deployment
Because the process involves records and document review, tools for extracting information, matching records, identifying exceptions, or routing work could be possible automation points. That is an inference about where automation might assist—not evidence that title insurers broadly use AI for title searches, chain-of-title review, defect detection, commitments, or policy issuance.
Without company-specific evidence, it would be inaccurate to describe a particular title insurer as using AI in underwriting or to suggest that an AI system independently determines whether a title is insurable. The sources establish the workflow, not the prevalence or operation of such systems.

The National Association of Insurance Commissioners (NAIC) describes AI use across insurance functions including underwriting, pricing, customer service, claims, marketing, and fraud detection. Its general insurance overview says insurers remain responsible for compliance with applicable insurance laws, regulations, and consumer-protection requirements when AI supports decisions. It also describes state regulators’ interest in how systems are used and governed, how risks are mitigated, and what models and data inputs are involved.
This is a broad insurer-oversight principle, not a title-insurance-specific AI rule. The NAIC page, updated April 3, 2026, reported that an AI Systems Evaluation Tool was being piloted by 12 states and anticipated consideration at the NAIC’s 2026 Fall National Meeting. That is the page’s dated status report; it does not establish the tool’s subsequent status or any title insurer’s use of AI.

Quick Recap
How to read an AI claim about mortgage or title decisions
- Identify the task. Ask whether the tool verifies borrower information, evaluates credit and eligibility, estimates property value, or reviews title evidence. Those are distinct jobs.
- Separate a proposal from a deployment. A survey naming an application as a priority does not show that a specific lender has implemented it.
- Check the applicable scope. The federal AVM standards cover specified uses; they do not automatically govern every tool described as AI.
- Ask what review and controls apply. A system’s output does not eliminate the institution’s responsibility to follow applicable requirements.
- Look for company-specific evidence for title AI. A description of the title-insurance workflow alone cannot establish that a named insurer uses AI or how its system works.
