Trump alleges mortgage fraud by Fed Governor Lisa Cook, but experts say it is hard to prove

A high-profile dispute over whether a public official misrepresented primary residence status has turned a technical mortgage topic into front-page news. Reports describe allegations that two mortgages taken out in 2021 were each treated as a primary residence, and they outline a legal fight over whether a president can remove a sitting Federal Reserve governor based on such claims. The details are still being contested, which is precisely why households should understand how primary residence rules actually work and where the legal guardrails are.

For conforming loans, the note and mortgage routinely include an occupancy clause that requires you to move in and use the home as your principal residence within 60 days of closing, and to continue doing so for at least one year, unless the lender agrees otherwise or true extenuating circumstances arise. This language is not a suggestion. It is a contractual promise, and breaching it can put you in default under the loan documents.

There are narrow carve-outs. Military borrowers on active duty who are temporarily away from home are still treated as owner-occupants. There are also family-care exceptions that allow a parent to buy for a disabled adult child, or an adult child to buy for a parent who cannot qualify on their own, while still receiving owner-occupied treatment. Lenders document those cases carefully at underwriting.

Lenders price to risk. Homes you truly live in tend to default less than rentals. That is why rates for investment properties are typically one-half to a full percentage point higher than for primary homes, and why required down payments and reserve rules are often stiffer. Over the life of a loan, that pricing gap can mean tens of thousands of dollars in interest.

Insurance costs move the same way. A landlord or rental-dwelling policy usually costs about 25 percent more than a standard homeowners policy because tenants and turnover increase risk. If you convert a home to a rental, insurers expect you to convert the policy too.

Taxes add another layer. Only your main home can qualify for the federal home-sale exclusion that shields up to 250,000 dollars of gain for single filers or up to 500,000 dollars for joint filers, provided you meet the ownership and use tests. You cannot have two main homes at the same time for this purpose, and whether a property is your “main home” turns on your actual use and facts on the ground.

State and local residency rules look at similar facts. Authorities often ask where you spend most of your time, where you vote, and where you are domiciled for income-tax purposes. Those factors do not replace what your mortgage documents require, but they tend to point in the same direction.

The core problem arises when a borrower represents in writing that they will occupy a property as a primary residence to get better pricing, while actually intending to use it as a rental or second home. In legal terms, that can become a false statement relied on by a lender, which is why prosecutors and regulators treat it as a species of bank or mortgage fraud in serious cases. The federal bank-fraud statute carries maximum penalties of up to 30 years in prison and a 1,000,000 dollar fine. Those are statutory caps, not typical outcomes, but the point is that the law takes false statements to financial institutions seriously.

Two things are easy to confuse. First, changing your mind after closing is not the same as lying. Life happens. Job relocations, illness, divorce, or other bona fide disruptions can make a move-in timeline unrealistic. Your documents contemplate extenuating circumstances and lender consent. Second, buying a second home this year does not retroactively turn last year’s purchase into a lie, so long as your original intent and occupancy met the contract. What gets borrowers into trouble is a paper trail inconsistent with the occupancy promise at the time of origination.

Academic work using administrative data shows that occupancy misrepresentation has been a persistent feature of the mortgage market, not just a relic of the pre-2008 boom. A 2023 Philadelphia Fed study identified more than twenty-two thousand likely misrepresentations in a large sample, and it found those loans tended to be larger and to default more often. The authors also noted that detection is often delayed because intent at the time of application is hard to observe.

At the same time, federal sentencing data suggest that the number of people sentenced for mortgage fraud each year is much lower than in the mid-2010s, even though the statutes remain on the books. Enforcement is real, but targets tend to be clearer cases or broader schemes rather than ambiguous life-events.

In the real world, your pattern of living usually decides the question. Mortgage underwriters document where you intend to live through affidavits and supporting records. If you say you will occupy within 60 days, they expect to see that happen, or to hear from you promptly if something beyond your control prevents it. For taxes, the IRS looks at whether a home was your main home for at least two of the five years before the sale, and state rules on domicile and voting reinforce that one-home-at-a-time principle.

If you are buying for a family member who cannot qualify on their own, ask early about programs that legitimately treat that purchase as owner-occupied. Lenders know the rules, and they will steer you to the right documentation when it applies.

Start with intent and timing. If you are relocating for work and truly plan to move into the new home, your occupancy promise should match your move-in plan. If you are buying a place that you will not live in most of the time, call it what it is and price it accordingly. A slightly higher rate now is cheaper than a misrepresentation that breaches your contract later. Market primers and consumer guides explain that lenders design lower rates and lower cash requirements for true primary homes because the risk is lower.

Then align your paperwork with your lived reality. Where you vote, register your car, file state returns, and receive your mail should point to the same place you call home on your loan. Consistency is not window dressing. It is what investigators and auditors check when they reconstruct intent. Finally, match your insurance to the use. If you convert a home to a rental after a year, convert the policy too. Insurers are explicit that landlord coverage costs more because it covers different risks.

Life does not always respect a 60-day clock. If a job falls through, a parent needs care, or a medical issue upends plans, communicate with your lender before the occupancy period expires. Lenders can permit deviations when circumstances are genuine and documented. If you move out permanently within the first year, the safest course is to seek written consent or to refinance into a product that matches the property’s new use. The goal is to keep your contract, your insurance, and your tax position aligned so that your intent remains clear.

News coverage can make it feel like every discrepancy is criminal. The reality is more nuanced. Media accounts describe a Justice Department focus on alleged misstatements by several political figures, while the individuals involved deny wrongdoing and frame the claims as politically motivated. That is a reminder to keep your own records clean rather than a reason to panic. For typical households, clear intent, consistent documentation, and transparent communication with the lender are what keep an honest life change from being misread as deception.

Treat the occupancy promise like a budget. Write down your move-in plan with dates, keep copies of utility starts and mail forwarding, and keep a short note on why the home is your main home. If a second home becomes your main home later, update the paper trail and talk to the lender about any promises still running. The phrase owner-occupancy mortgage fraud may sound abstract, but it is ultimately about whether your words and your life matched at the moment you signed. If they did, and you document it, you are doing the right thing.
