Conventional Loan and FHA Options for a Dentist With Strong Credit

The Quick Read: A conventional loan is a mortgage that no government agency insures or guarantees. For a dentist with strong credit, it often costs less over time than FHA, because conventional mortgage insurance responds to credit and FHA’s premium does not. FHA still wins in a few files, mostly where student debt is heavy. Run both before you pick one.

What a Conventional Loan Is

A conventional loan is a mortgage made by a private lender and not backed by a federal agency. Most follow Fannie Mae and Freddie Mac standards so the lender can sell the loan afterward. A loan within the size limits those companies set is called conforming. Every conforming loan is conventional, but not every conventional loan is conforming. Loans above the limit are jumbo or portfolio loans, and each lender sets its own rules for them.

Conventional loans work for a primary home, a second home, or a rental.

What FHA Offers a Dentist

FHA loans are insured by HUD and made by approved lenders. Lendmire is a mortgage broker, so it arranges them through wholesale lenders and does not lend. The FHA loan programs the network places run up to 96.5% financing, with a 3.5% minimum investment at a decision score of 580 or higher. Across the wholesale programs Lendmire places files with, 580 is the floor.

Strong credit doesn’t change that picture much. A dentist with a 760 score and a dentist with a 640 score both pay the same FHA mortgage insurance structure. The upfront premium is 1.75% of the base loan, and it is financed into the loan. The annual premium runs from 0.15% to 0.75% of the balance. It depends on term, loan amount and LTV, not on credit score. That is the key point for a strong-credit borrower.

HUD’s published rules for FHA premiums tie the annual premium’s length to the original LTV. On a thirty-year loan above 90% LTV, it lasts the full term. At 90% LTV or below, it ends after eleven years. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.

How the Loan Is Underwritten, Step by Step

1. Application and Loan Estimate. The lender gives you a Loan Estimate after you apply. It shows estimated costs. It is not an approval.

2. Credit review. Conventional files run through automated underwriting. Fannie Mae’s system dropped its hard 620 minimum for new files, and it now weighs the whole risk picture. Individual lenders can still add their own floors. For FHA, the decision score tiers set the minimum investment. A strong score clears both. Credit is rarely what stops a dentist’s file.

3. Income documentation. This is where dentists get tested, and the next section covers it.

4. Debts. Student loans and practice debt enter the ratio. Both programs cover this differently.

5. Appraisal. An FHA appraisal sets value and also checks that the home meets HUD’s minimum property standards. The appraiser may flag repairs that must be done before the loan is insured. A conventional appraisal focuses on value and condition.

6. Underwriting decision and closing. The lender issues a Closing Disclosure before closing. Everything above is subject to lender guidelines and full file review.

Where Dentist Files Get Tested: Income

An associate dentist on W-2 pay is a simple file. Pay stubs, W-2s and an offer letter or employment history carry it.

A practice owner is different. Both programs qualify a self-employed borrower on net taxable income after the lender’s analysis, not on collections or bank deposits. Heavy deductions lower the income a lender can use to qualify. That surprises owners who show strong cash flow but report low taxable income on their tax returns.

For conventional files, Fannie Mae’s self-employed guidelines call for signed federal returns, typically for the past two years, with all schedules. The lender then completes a cash flow analysis and keeps it in the file. If you own part of a partnership or S corporation, that income counts only when you can document access to it. A history of cash distributions, or enough business liquidity, does that. Income that stays inside the practice may not count.

FHA is similar. HUD has required two years of individual returns and, in many cases, business returns too. Confirm the current handbook language with your loan officer, since HUD updates these rules.

A dentist who just bought or started a practice has a short history. Some conventional flexibility exists for established businesses. Ask the loan officer before assuming either way.

Student Loans Can Move the Ratio

Large professional-school debt is common for dentists. FHA and conventional can treat the same balance differently, especially when the loan is deferred or on an income-driven plan with a low or zero payment. HUD changed its deferred-loan treatment over time, and the details are in the handbook.

On FHA, the base ratio pair is 31/43 (housing to total debt) with no compensating factors. Documented compensating factors can reach 40/50 at the top tier, and the automated finding governs most files. Conventional automated underwriting can approve higher ratios than manual review, depending on the file.

The practical move: ask the loan officer to run the same file both ways. The program that counts your debt more gently can decide which loan you can carry.

Loan Size: The First Filter

Price often decides the product before credit does. County loan limits apply to both programs, and they are not the same. HUD sets a floor and ceiling for FHA limits. The floor covers lower-cost areas, and higher-cost counties get limits between the floor and the ceiling. FHFA sets the conventional side, and its conforming loan limits also vary by county.

In many counties, the conventional limit is larger than the FHA limit. A dentist buying in a higher-priced area may find FHA too small for the home. Look up your county’s figures before you shop. Above the conforming limit, you are into jumbo territory, where lenders set their own credit, reserve and down payment rules.

Conventional vs. FHA at a Glance

Mortgage Insurance: How It Ends

Conventional private mortgage insurance has an exit. Under federal law, the servicer must end it automatically when your balance is scheduled to reach 78% of the original value, if you’re current. You can ask for cancellation at 80%. The CFPB’s examination procedures lay out the 78% rule. That law covers private mortgage insurance, not FHA.

FHA premiums follow HUD’s duration rules above. With a small down payment, they can last the full term. Some borrowers later refinance into a conventional loan to remove them.

Where the General Rule Breaks

• Strong credit, small down payment. Conventional mortgage insurance still applies under 20% down, but a high score lowers its cost. FHA’s structure gives you no such credit. This is why conventional usually wins for a strong-credit dentist.
• Strong credit, heavy student debt. If FHA counts your loans more gently than conventional does, FHA can be the loan that fits the ratio. Strong credit doesn’t always mean conventional wins.
• Owner with thin returns. Both programs use net taxable income. Neither will credit deposits or collections.
• Buying the office. FHA needs at least one borrower to live in the home as a principal residence within 60 days of signing and intend to stay at least one year, per HUD’s occupancy guidance. It is not available for a practice property or a second home. A practice purchase is a separate financing decision.
• Refinance later. If you start in FHA, an FHA-to-conventional move is possible. Lendmire’s piece Does an FHA-to-Conventional Cash-Out Refinance Need Better Credit? covers how the credit side works.

What the Decision Looks Like in Practice

Picture a dentist with a high score, a modest down payment and a large student balance. On conventional, the credit helps the insurance cost, but the loan balance may push the debt ratio. On FHA, the ratio may pass, but the premium stays the same regardless of the score.

Now picture an associate on a W-2 with a high score and 10% down. Conventional is likely the better fit, since mortgage insurance can be cancelled later and the score earns a better price.

Neither answer is automatic. The loan officer should run both programs on your real file, then compare the full monthly picture: principal and interest, mortgage insurance, taxes and homeowners insurance. The actual numbers.

Key Terms Defined

Conforming loan: A conventional loan within the size limit that Fannie Mae and Freddie Mac will buy.

Jumbo loan: A loan above the conforming limit, with rules set by each lender.

Private mortgage insurance (PMI): Insurance on a conventional loan with a small down payment, which can be cancelled.

Mortgage insurance premium (MIP): FHA’s upfront and annual insurance charge, set by HUD’s rules.

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

Loan Estimate: The disclosure that shows estimated loan terms and costs. It is not an approval.

Documents to Have Ready

• Two years of signed federal tax returns with all schedules
• K-1s for any partnership or S corporation share
• Year-to-date profit and loss if the file calls for it
• Student loan statements showing balance and payment status
• Recent bank statements and the source of your down payment
• Pay stubs and W-2s if you’re an associate

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