Debt-to-Income: The Number That Usually Decides It

Debt-to-income ratio, or DTI, compares your monthly debt obligations to your gross monthly income. It is calculated two ways. The front-end ratio, sometimes called the housing ratio, looks only at the proposed housing payment: principal, interest, property taxes, homeowners insurance, mortgage insurance if applicable, and any homeowners association dues. The back-end ratio adds every other monthly debt on your credit report.

Back-end DTI is the one that most often kills or shrinks an approval. Two buyers with identical incomes and identical credit scores can qualify for very different loan amounts purely because one has a car payment and student loans and the other does not. This is also why paying off a car loan can raise your buying power more than saving another few thousand dollars for the down payment, and it is worth modeling both with your lender before deciding.

Note what DTI uses: gross income, before taxes, and only income the lender can document and count. It does not consider your grocery bill, your childcare cost, your 401(k) contribution or your utilities. That means a buyer can be approved for a payment that feels uncomfortable in practice. Deciding what you actually want to spend is a separate exercise from finding out what you can be approved for, and we encourage clients to do both.

How Do Student Loans, Car Payments and Credit Cards Actually Count?

The details matter here, and they surprise people. Revolving accounts like credit cards are generally counted using the minimum payment shown on your credit report, not the balance and not what you actually pay each month. So a card with a large balance and a small minimum may hurt your DTI less than expected, while a card you pay in full monthly still shows a minimum payment that counts against you. Carrying a low balance and paying it off before applying can help both your score and your ratio.

Installment debts such as car loans, personal loans and furniture financing count at their scheduled monthly payment until they are paid off. Lenders will typically exclude a loan with only a few payments remaining under certain conditions, so ask. Leases generally count for the full payment regardless of how close the lease is to ending, because a replacement vehicle is expected.

Student loans are the most complicated category and the rules differ by loan program and have changed repeatedly over the years. Depending on the program, a payment in deferment or forbearance, or an income-driven payment of zero, may be counted using an assumed percentage of the balance rather than the actual payment. Do not assume that because you currently pay nothing, nothing counts. Bring your current statements to your loan officer and ask specifically how your loans will be treated under each program you are considering.

Also counted: child support and alimony you pay, co-signed loans where you are legally obligated even if someone else makes the payments, and installment debt on a business account if it appears on your personal credit. Not typically counted: utilities, insurance other than the housing-related kinds, cell phone bills and subscriptions.

Employment History and Income That Is Harder to Document

Underwriters want income that is stable, likely to continue and verifiable. A salaried W-2 employee with two years at the same employer is the easy case: recent pay stubs, W-2s and a verbal verification of employment near closing, and it is done. Everything else requires more explanation, and none of it is disqualifying if you prepare for it.

Job changes are usually fine, particularly within the same field or with an increase in pay. What draws scrutiny is a gap in employment, a change from salaried to self-employed, a move into a fundamentally different industry, or a shift from guaranteed pay to variable pay. A written letter of explanation and an offer letter often resolve it. Starting a new job before closing is manageable, but tell your lender immediately rather than letting them discover it.

Variable income is where files slow down. Bonus, overtime and commission income are typically averaged over a documented history and may not count at all if the history is short or the trend is declining. If commission or bonus makes up a large share of your income, ask your loan officer early exactly how much of it will be used, because the answer materially changes your approval amount.

Self-employment has its own path. Lenders generally rely on your filed tax returns and average the net income after business deductions, which is the crux of the issue: the deductions that reduce your tax bill also reduce your qualifying income. Expect requests for two years of personal and possibly business returns, a year-to-date profit and loss statement, and verification that the business is still active. If you are self-employed and planning to buy in the next couple of years, talk to both your CPA and a loan officer before you file, because how you handle deductions has a direct effect on what you can borrow.

Assets and Reserves: Why Lenders Want You to Have Money Left Over

You need funds for the down payment and closing costs, but underwriters also look at what remains afterward. Reserves are liquid assets you still hold after closing, usually expressed as a number of months of the new housing payment. The logic is simple: a borrower with several months of payments in the bank survives a broken HVAC or a gap between paychecks, and one with nothing does not.

Whether reserves are required, and how many months, depends on the loan program, the property type, your credit profile and the strength of the rest of the file. Multi-unit properties, investment properties, condominiums and higher-DTI files tend to draw reserve requirements more often than a straightforward single-family primary residence. Reserves are also one of the most common compensating factors: a file that is weak on DTI can sometimes be approved because the reserves are strong.

What counts as reserves is broader than a checking account. Savings, money market accounts, and often a percentage of vested retirement account balances can be used, though retirement funds are usually discounted to account for taxes and penalties. What does not count is the proceeds of a loan you have not taken, equity in a house you have not sold, or cash you cannot document.

Sourcing and Seasoning: Where Did This Money Come From?

Anti-money-laundering rules and agency guidelines require lenders to know the origin of the funds you bring to closing. Two words describe this. Sourcing means documenting where a deposit came from. Seasoning means the money has sat in your account long enough, typically across two or three months of statements, that no explanation is needed.

Practically, expect to be asked about any deposit that is large relative to your normal income pattern. Selling a car, a tax refund, a bonus, a reimbursement from a friend, cash you deposited from a side job, or a transfer between your own accounts will all generate a request for a paper trail. Undocumentable cash is genuinely a problem, no matter how legitimate its origin.

Gift funds are allowed by most programs but must be handled correctly. The donor signs a gift letter confirming the money is a gift and not a loan, and the lender will typically want evidence of the transfer and sometimes evidence of the donor’s ability to give it. Who may give a gift depends on the program, with some restricting it to family or documented close relationships. Do not have a relative hand you cash or deposit money into your account without telling your loan officer first, because unwinding that after the fact is far harder than doing it correctly at the start.

Pre-Qualification, Pre-Approval and Underwritten Approval Are Not the Same

These terms get used loosely, including by agents, and the difference matters enormously when you are competing for a house in Richmond.

A pre-qualification is typically based on information you stated verbally or in an online form, sometimes with a credit check and sometimes not. Nothing has been verified. It is a useful budgeting exercise and almost worthless as a negotiating tool.

A pre-approval normally involves a credit pull and a loan officer’s review of your income and asset documentation, producing a letter with a maximum purchase price. This is the standard document sellers expect with an offer. Its quality varies widely depending on how much the loan officer actually collected and reviewed.

An underwritten pre-approval, sometimes marketed under other names, means an actual underwriter has reviewed your full file and issued an approval subject only to the property, the appraisal and a final verification of your circumstances. This is meaningfully stronger, and in a competitive situation it lets your agent tell the listing agent something specific and credible about why your financing will close. If you are shopping in a segment of the Richmond market where multiple offers are realistic, ask your lender whether they offer this.

The Property Can Fail Underwriting Even If You Do Not

Buyers often forget that the lender is underwriting the collateral as well as the borrower. The appraisal establishes value and, depending on the program, also comments on condition. If the appraised value comes in below the contract price, the lender will lend against the lower figure, which means you either renegotiate, bring additional cash, or terminate under your appraisal contingency.

Condition matters too. Government-backed programs in particular have minimum property standards, and an appraiser may call for repairs before the loan can close: peeling paint on an older home, a missing handrail, an active roof leak, exposed wiring, inoperable systems or a broken window. In Richmond’s older neighborhoods these callouts are not unusual, and they can require negotiation with a seller who did not expect them.

Property type adds another layer. Condominium financing brings project-level review of the association’s budget, reserves, owner-occupancy ratio, litigation and insurance, and an otherwise qualified buyer can be denied because of the building rather than themselves. Multi-unit properties, manufactured homes, homes on private wells and septic systems, and unusually large acreage all carry their own additional requirements. Tell your lender the property type as soon as you identify a house.

How Conventional, FHA, VA and USDA Underwriting Differ

All four programs look at the same pillars but weight them differently, and the right one depends on your specific profile rather than on which has the lowest advertised rate.

Conventional loans follow Fannie Mae and Freddie Mac guidelines and are generally the most credit-sensitive, with pricing and mortgage insurance cost tied closely to your score and down payment. They tend to offer the most flexibility on property condition and are usually the smoothest path when your credit and documentation are strong.

FHA is insured by the Federal Housing Administration and is designed to be more forgiving on credit history and, often, on ratios, which makes it a common solution for buyers with a thinner or bruised credit profile. The tradeoff is mortgage insurance that generally lasts longer and minimum property standards that are stricter.

VA loans, for eligible service members, veterans and certain surviving spouses, are among the strongest programs available. There is no required down payment for most eligible borrowers and no monthly mortgage insurance, and VA underwriting uses a residual income analysis in addition to ratios, which is a genuinely different and often more generous approach. VA also has its own minimum property requirements.

USDA guaranteed loans support home purchases in designated rural areas and can require no down payment for eligible borrowers, but they carry both household income limits and property location limits. This matters locally: while the City of Richmond and the developed parts of Henrico and Chesterfield are not eligible, parts of Goochland, Powhatan, Hanover and outer Chesterfield do fall within USDA-eligible areas. That surprises a lot of buyers who assume “rural” means far away. Check the current eligibility map for a specific address, since boundaries are periodically revised.
