Conventional Loan Options for a Dentist Who Owns a Practice

The Quick Read: A dentist who owns a practice can usually use a conventional loan, but the file is built from personal income documented through tax returns, not from what the practice collects. Ownership of 25% or more makes you self-employed in the agencies’ eyes, so the lender analyzes your business income, your history, and any practice debt you have signed for. Taxable income, not production, drives the answer.

What Does “Conventional” Mean for a Practice Owner?

A conventional loan is a mortgage that follows Fannie Mae or Freddie Mac rules and isn’t backed by FHA or VA. For a dentist, it is a loan on the home you live in. It does not finance the practice, the equipment, or a freestanding office building.

That distinction trips up many searches. Practice acquisition loans, SBA loans, and commercial real estate loans are business products. They matter here only because they can show up in your personal debt ratio.

Across the wholesale programs Lendmire works with, the conventional envelope on a principal residence is 97% leverage for a first-time buyer (3% down) and 95% for everyone else (5% down). Those figures are subject to lender guidelines and full file review. They are not a commitment to lend. You can read how Lendmire’s conventional loan programs are arranged through wholesale lenders in the states it is licensed for consumer lending.

How Is a Dentist’s Loan Underwritten, Step by Step?

The process runs in six steps. Each one has a place where a practice owner’s file differs from a W-2 file.

1. Classification. The application records your ownership percentage and entity type: sole proprietor, S corporation, or partnership or PLLC. Fannie Mae applies its self-employed rules once your ownership reaches 25% (Fannie Mae Selling Guide). K-1s and entity documents prove the percentage.

2. Documents. The base is signed personal and business federal tax returns, generally for the last two years. Under Fannie Mae’s automated underwriting, the system may decide one year is enough in some files. Fannie Mae’s announcement SEL-2023-09 describes the two-year standard and the one-year allowance for businesses that have existed for five years.

3. Cash flow analysis. The lender completes a written analysis, Fannie Mae’s Form 1084 or an equivalent, and keeps it in the file. It looks at whether income recurs, how pass-through income should be treated, and the trend in gross income, expenses, and taxable income. The Fannie Mae Selling Guide on self-employed borrowers sets this out. Freddie Mac uses an equivalent form and income calculator.

4. Viability. The underwriter considers distributions you have taken or could take while keeping the practice healthy. Pulling more than the business can afford doesn’t help the file.

5. Debts. Practice debt you personally guaranteed, such as an acquisition note, equipment loan, or SBA loan, counts in your ratios unless exclusion tests are met. More on that below.

6. Appraisal and property. The home gets a normal residential appraisal. The loan must be secured by residential property.

Across the wholesale programs we place files with, the automated finding governs most files. The ceiling on the total debt ratio is 50%, and the wholesale floor is a 620 decision score. Subject to lender guidelines and file review, as always.

Why Does Taxable Income Matter More Than Collections?

Lenders review your file on the income that appears on your returns, after deductions. Gross production and bank deposits don’t substitute for it.

That is the central tension for dentists. Equipment purchases, depreciation, and heavy expense write-offs lower taxable income, and a lower figure means a lower coverage figure. Underwriters add back certain non-cash items such as depreciation, and they study the year-over-year trend. Rising income helps. Declining income is a red flag, and a lender may rely on the lower year.

Picture a practice owner whose collections grew steadily but who bought a large equipment package in the latest tax year. The return shows less profit than the prior year. The underwriter will notice the dip, look at what drove it, and decide how much to credit. A CPA’s explanation of the add-backs can help, but the documented numbers decide.

How Do Practice Debts Affect the Mortgage?

Practice debt in your name can raise your ratios, but you can sometimes exclude it with documentation. This is the part most dentists don’t expect.

A personally guaranteed business loan that shows on your credit report generally counts. Fannie Mae allows exclusion when the account has no delinquency history, the business paid the obligation from company funds (for example, 12 months of canceled company checks), and the cash flow analysis already accounted for the payment (Fannie Mae Selling Guide on monthly debt obligations). Freddie Mac has a similar 12-month test, and its returns must show the related business expense.

The practical takeaway: start collecting proof of business-paid payments early. If you are about to buy a practice, think about sequencing. A new acquisition note may land on your credit report right before your home application, so some dentists time the home purchase before the practice deal closes, or at least plan the file around it.

Where Do the General Rules Break?

Six edge cases come up for practice owners. In each, the standard path changes.

A recent practice purchase or startup. Fannie Mae can consider income when the latest signed returns show a full 12 months of self-employment from the current business, and the file documents prior income at the same or a greater level. Freddie Mac asks for a combined two-year history of the current business and a prior job in the same or a similar occupation, with at least one year of self-employment on the returns (Freddie Mac Guide §5304.1). An associate who becomes an owner is a natural fit for this path, since the prior work is in the same field. That is our read of the rule, not an agency statement about dentists. The tax filing cycle matters: a practice bought mid-year may not show 12 months on a filed return until the next one.

Associate with a small ownership stake (under 25%). Fannie Mae treats this as K-1 income, not self-employment. The lender may use your proportionate share of earnings on the K-1, with two years of signed personal returns and the K-1, plus a verbal verification of employment. For a borrower who recently acquired nominal ownership in a professional services partnership, such as a medical practice, after an established employment history there, an exception to the two-year requirement may apply (Fannie Mae on K-1 income).

Using practice cash for the down payment or reserves. If you qualify on self-employment income and also use business assets, the lender runs a business cash flow analysis to confirm the withdrawal won’t hurt the practice. Personal funds avoid that step. They also keep one more option open: Fannie Mae can waive the business returns when personal funds cover the down payment, closing costs, and reserves, you have been self-employed in the same business at least five years, and your individual returns show rising self-employment income.

Home and practice in the same building. Fannie Mae will purchase loans on properties with some business use, including a doctor’s office, but the property must stay residential in character. A freestanding dental office, or a building where commercial use dominates, is outside this consumer program. Confirm the specific conditions with your loan officer before you write an offer on a live/work property.

A loan above the conforming limit. Jumbo loans fall outside the agency framework and follow lender-specific rules. Don’t assume the flexibilities above carry over. Among the wholesale jumbo lanes Lendmire places, the decision score starts at 660 and leverage reaches 90%, with a 50% ratio ceiling on the fixed lanes. County and national limits change, so check your county’s current limit before you set a price range.

A co-borrower’s self-employment income. If it isn’t used to qualify, the lender doesn’t have to document it. Business debt the co-borrower is personally obligated on still counts.

Key Terms Defined

Self-employed (agency definition): A borrower with an ownership interest of 25% or more in a business.

Form 1084: Fannie Mae’s cash flow analysis form that lenders use to turn business returns into qualifying income.

K-1: The tax form showing your share of a partnership’s or S corporation’s income, which also verifies your ownership percentage.

Add-back: A non-cash expense, such as depreciation, that a lender may add back to your taxable income.

Debt-to-income ratio (DTI): Your monthly debts divided by your monthly gross income.

Jumbo loan: A mortgage above the conforming loan limit, underwritten to lender-specific rules.

How Does Mortgage Insurance Work on a Low-Down-Payment File?

Mortgage insurance is required when leverage is above 80% of value. On a conventional loan it can come off. You may request cancellation at 80% of the original value with a good payment history, no subordinate liens, and no decline in value. The servicer must end it automatically at 78%, under the Homeowners Protection Act. Published typical annual premiums run from 0.58% to 1.86% of the balance. That is a range, not a quote, and your actual figure depends on score and leverage.

A dentist with strong cash may put more down to avoid mortgage insurance, but a large down payment from practice funds can bring the extra analysis described above. It’s a genuine trade-off. Putting 20% down from personal savings can keep the file simpler. Putting 5% down and preserving cash for the practice may be wiser if the practice needs a working-capital cushion.

When Is Conventional the Right Call, and When Isn’t It?

Conventional tends to fit when your returns show strong, stable taxable income and your loan sits at or below the conforming limit. It becomes less comfortable when heavy deductions shrink your taxable income, or when the loan is large.

If your returns understate your cash flow, a bank statement loan reads income from deposits instead. Lendmire’s piece How to Qualify for a Bank Statement Loan as a Dentist Who Owns the Practice walks through that path. It usually trades a higher cost or lower leverage for easier income documentation, so it isn’t automatically better. It’s a flip point, not a default.

Here is the decision in practice. Gather two years of personal and business returns, K-1s, and a list of every practice debt you’ve guaranteed. Ask your CPA what the returns show after add-backs. Then compare the conventional number to what you want to borrow. If the gap is small, a conventional file with a clean debt-exclusion package may close it. If the gap is wide, look at other structures before you shop for a house.

Tax treatment can depend on your situation; borrowers should speak with a qualified tax professional before relying on any deduction or credit.

Common Reasons Practice-Owner Files Stall

• Returns not signed or missing a schedule or K-1.
• Business returns that don’t match the application.
• Practice loans that appear on the credit report with no proof they are paid by the business.
• A recent acquisition that leaves under 12 months on the return.
• Practice cash used for the down payment without supporting statements.
• Income that fell in the latest year with no explanation.

Self-employed files need more paperwork, so they ask more of you early. Pulling everything together before you apply is a more affordable way to avoid delays.
