FHA and conventional mortgages are not universally better or worse; the right choice depends on your credit profile, down payment, property, and the actual offers lenders give you. FHA financing can be advantageous when your credit is weaker or your down payment is small. A conventional loan often costs less for a borrower with good credit and a medium down payment. The reliable way to decide is to request both Loan Estimates for the same home, price, down payment, term, rate-lock period, and closing date, then compare mortgage insurance, lender charges, cash to close, and the projected cost over the time you expect to keep the loan.
This guide explains how each program works, where the biggest cost differences arise, what current credit and down-payment rules actually say, and how to compare offers without relying on generic rate advertisements.

Which mortgage is better for my purchase?
Choose FHA when its lower credit and down-payment requirements produce a lower overall cost or make approval possible. Choose conventional when your credit, down payment, and debt profile qualify for better pricing and a lower or shorter mortgage-insurance burden. Neither rule guarantees the best result: lender pricing, property eligibility, loan size, and how long you keep the loan can change the answer.
The Consumer Financial Protection Bureau (CFPB) says FHA can often be the least expensive option for borrowers with lower credit scores or smaller down payments. It also says that for borrowers with good credit and a medium 10%–15% down payment, FHA loans tend to be more expensive than conventional loans. These are tendencies, not promises. Your own Loan Estimates are more useful than a national rule of thumb.

What is an FHA mortgage?
An FHA mortgage is made by a private lender and insured by the Federal Housing Administration. FHA insurance protects the lender against certain losses; the federal government is not sending the borrower a direct loan. HUD describes Section 203 mortgage insurance for eligible one- to four-family homes, generally for a borrower’s primary residence. Start with HUD’s mortgage-insurance program information and the applicable lender requirements for the property you want.
FHA rules include program limits for credit, loan-to-value, mortgage insurance, property condition, and loan amount. A lender still reviews income, assets, debts, occupancy, the appraisal, and its own underwriting standards. Meeting an FHA threshold therefore does not create an approval entitlement.
FHA loan limits are not one national number. HUD publishes limits by county and property type and updates them periodically. Before assuming a purchase price fits, check the current HUD limit for the county and the number of units; do not rely on an old online example.
What is a conventional mortgage?
A conventional mortgage is a private loan that is not insured or guaranteed by a specific federal housing program. Conforming conventional loans follow eligibility and loan-limit rules associated with the major housing-finance agencies, while other conventional products may have different underwriting and pricing. The CFPB’s conventional-loan overview explains the broad category, but your lender must identify the exact product.
There is no single universal conventional minimum credit score that applies to every borrower and every automated or manual underwriting path. In the cited April 22, 2026 Fannie Mae Selling Guide, manually underwritten fixed-rate loans have a 620 minimum and manually underwritten adjustable-rate mortgages have a 640 minimum. The same guide states that Desktop Underwriter casefiles have no minimum credit-score requirement in that guide’s stated context. Lenders can apply overlays, and other conventional programs can set different conditions, so treat those figures as product-specific guidance rather than a blanket rule.

How do FHA and conventional down-payment and credit rules differ?
FHA links its maximum financing to a decision credit score. CFPB consumer guidance describes FHA down payments as low as 3.5%. HUD Handbook 4000.1 says a minimum decision credit score of 580 or more can be eligible for maximum financing, while scores from 500 through 579 are limited to 90% loan-to-value. That means a borrower in the 500–579 band generally needs at least 10% equity under that rule, before considering lender overlays or other requirements.
Conventional down-payment and score requirements depend on the specific product, automated findings, property, occupancy, and borrower factors. A lender might offer a low-down-payment conventional option, but the rate, PMI, reserves, and eligibility conditions can differ materially from another lender’s product. Ask which underwriting path produced the quote and whether any lender overlay applies.
Do not compare only the minimum cash percentage. A smaller down payment leaves more money available for reserves and closing, but it usually increases the loan balance and can increase mortgage-insurance charges. A larger down payment may lower the balance and insurance cost while reducing liquid savings. CFPB’s guidance on deciding how much to put down supports evaluating the trade-off rather than treating the largest possible down payment as automatically best.
Which mortgage-insurance costs should I compare?
FHA financing requires mortgage insurance with an upfront premium and annual premiums collected through the loan’s payment structure. The exact amounts depend on the FHA loan terms and current rules shown in your disclosures. The upfront charge may be financed or paid at closing under the lender’s offer, so inspect both the amount and how it changes your principal balance.
Conventional loans typically require private mortgage insurance (PMI) when the down payment is below 20%, although the precise requirement and pricing depend on the product and risk profile. Borrower-paid PMI is subject to federal cancellation and termination provisions when applicable, but the timing and eligibility conditions depend on the loan and payment history. The CFPB’s Homeowners Protection Act examination procedures describe the federal framework.

FHA mortgage insurance and conventional PMI are not interchangeable labels. Compare the upfront amount, monthly amount, projected duration, and any conditions for ending coverage. A conventional quote with a lower rate can still cost more after PMI and lender fees; an FHA quote with a lower cash requirement can still cost more over a long holding period because of its insurance structure.
Which is cheaper, FHA or conventional?
There is no universal lower-cost winner. CFPB says FHA can often be cheaper for lower-credit or smaller-down-payment borrowers, while conventional can often be cheaper for good-credit borrowers with a medium down payment. The comparison must include interest, mortgage insurance, lender charges, and the time you expect to keep the loan.
For a borrower with strong credit and 10%–15% down, test conventional particularly carefully because FHA may be more expensive in that situation. For a borrower with weaker credit or only a small down payment, include FHA because its pricing and eligibility may be more favorable. A lender’s advertised rate is not enough to establish the winner; rates may assume different points, insurance, lock periods, or borrower qualifications.
How do county loan limits and property rules affect the choice?
Both FHA and conforming conventional loan limits vary by location. FHA limits also vary by property type, such as one-unit versus multiple-unit homes, and HUD updates them annually. Conventional conforming limits likewise depend on county. Use the current official HUD and applicable conventional-limit lookup for the property’s county before relying on any example.

Conventional eligibility depends on the particular program and property rules. A home’s unit count, occupancy, condition, appraisal, and intended use can change which offers are available, so tell each lender the same facts at the start.

How should I compare FHA and conventional Loan Estimates?
Request both estimates for identical assumptions. The CFPB’s Loan Estimate explainer is the reference for the form and its sections.
- Give each lender the same scenario. Use the same purchase price, down payment, loan term, occupancy, property type, desired closing date, and rate-lock period. Different assumptions produce a misleading comparison.
- Ask for both programs. Tell the lender you want an FHA estimate and a conventional estimate, not a generic quote. If the lender cannot offer one option, request the reason and seek another qualified lender.
- Check the loan terms. Confirm fixed versus adjustable rate, term length, interest rate, points, prepayment provisions if any, and whether the rate is locked. Do not compare a locked FHA quote with an unlocked conventional quote as if they were equivalent.
- Separate lender charges from pass-through costs. Review origination charges, underwriting or processing fees, discount points, appraisal, credit-report, title, recording, and other disclosed costs. Some third-party charges may be similar, but they still belong in the cash-to-close comparison.
- Identify every insurance charge. For FHA, locate the upfront and annual mortgage-insurance amounts. For conventional, locate PMI, the assumed cancellation or termination conditions, and any lender-paid PMI trade-off reflected in the rate.
- Compare cash to close and payment. Look at the amount needed at closing, principal and interest, mortgage insurance, escrowed items, and the total projected monthly payment. A lower cash requirement is valuable only if the ongoing cost fits your budget.
- Run a holding-period comparison. Compare the projected total paid over the period you realistically expect to keep the loan. Include the starting balance, upfront insurance, monthly insurance, interest, and lender charges. If your plans are uncertain, ask the lender for more than one payoff or refinance horizon rather than relying on a single break-even date.
- Verify the assumptions before choosing. Ask what credit score, debt-to-income calculation, reserves, appraisal conditions, and property rules the quote assumes. Obtain revised estimates if the down payment, rate lock, purchase price, or closing date changes.
What numbers matter most on each estimate?
| Item | Why it matters | What to ask |
|---|---|---|
| Interest rate and annual percentage rate | The rate affects principal-and-interest payments; APR incorporates certain finance charges but is not a complete lifetime-cost measure. | Are both rates locked for the same period, and are points included? |
| Upfront mortgage insurance | FHA’s upfront premium can increase cash needs or the financed balance. | Is it financed or paid at closing, and what balance does the estimate assume? |
| Monthly mortgage insurance | Insurance can dominate the difference between otherwise similar payments. | How much is charged each month, and under what conditions can it end? |
| Loan amount and cash to close | A lower down payment preserves cash but usually increases borrowing. | Does the cash figure include all required funds, credits, and prepaid items? |
| Lender and discount charges | Fees and points can erase an apparent rate advantage. | Which charges are optional, and what rate would apply without points? |
| Projected cost over your holding period | The cheapest first-year payment may not be cheapest over several years. | What is the estimated total paid and remaining balance at the date you may sell or refinance? |
Use the same comparison horizon for both offers. Do not add speculative future refinance savings or assume home-price appreciation; those outcomes are not established by the Loan Estimate.

Lower credit score: FHA’s published score-linked financing rules may allow a structure that a conventional lender will not price as favorably. A score of 580 or higher can be eligible for maximum FHA financing under HUD’s rule, while 500–579 is limited to 90% loan-to-value. The lender still evaluates the full application.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Small down payment: CFPB describes FHA down payments as low as 3.5%. If preserving cash is important, compare the resulting FHA insurance and financed balance with a low-down-payment conventional option rather than assuming the smaller check at closing means lower cost.
Property or occupancy that fits FHA: For an eligible primary residence within the applicable county and property limits, FHA may be worth including. Confirm unit count, condition, appraisal, and occupancy rules before treating it as available.

Which borrower profiles should examine conventional first?
Good credit with a medium down payment: CFPB specifically cautions that FHA tends to be more expensive than conventional for good-credit borrowers putting down 10%–15%. Compare PMI, rate, points, and total cash rather than looking at the rate alone.
Ability to reach a lower insurance burden: A larger down payment can reduce or eliminate conventional PMI, subject to the product’s rules. Weigh that saving against the liquidity you would give up and any emergency reserves you need.
Eligibility through automated underwriting: The cited Fannie Mae guide has different score treatment for manually underwritten loans and Desktop Underwriter casefiles. Ask the lender which path applies and what additional requirements it has; do not assume the guide’s automated-underwriting statement guarantees approval.
What mistakes make this comparison unreliable?
- Comparing different loan sizes: A 3.5% FHA down payment and a 10% conventional down payment create different balances. Match the down payment dollars or clearly model the difference.
- Using an old loan-limit example: Limits change by county and year. Verify the current official limit for the property.
- Treating a score threshold as approval: FHA’s 580 and 500–579 parameters are eligibility rules for financing levels, not a promise that a lender will approve the file.
- Ignoring insurance duration: Compare when PMI may end under applicable rules and how FHA insurance is disclosed for the offered loan.
- Focusing on the advertised rate: Points, lender credits, mortgage insurance, and lock periods can reverse the result.
- Requesting estimates at different times: Market pricing changes. Request both close together and record the date, lock status, and assumptions.
- Failing to disclose occupancy: FHA generally concerns primary residences, and conventional terms vary by intended use. Give accurate occupancy information.
- Assuming one lender represents the entire market: Lenders can apply overlays and price risk differently. Compare multiple actual offers while keeping the scenario identical.
What should I ask the lender before choosing?
- What exact FHA or conventional product is this, and is the rate fixed or adjustable?
- Which credit score and underwriting path did you use?
- What lender overlays apply beyond the published program rules?
- How much is the upfront FHA mortgage insurance, and is it financed?
- What is the monthly FHA insurance or conventional PMI amount?
- When and how could the conventional PMI end under this loan’s terms?
- What county and property-type loan limit did you use?
- What property, appraisal, occupancy, reserve, or debt conditions could change the estimate?
- How long is the rate locked, and what happens if closing is delayed?
- Can you provide a revised Loan Estimate if I change the down payment or points?
Bottom line: compare the offers, not the labels
FHA is often the better starting point for a buyer with lower credit or limited cash, while conventional deserves priority testing for a buyer with good credit and a medium down payment. Those are evidence-based starting points, not universal verdicts. The decision should come from side-by-side Loan Estimates using the same assumptions, with mortgage insurance, cash to close, lender charges, and your expected holding period included. Verify current county limits and product rules, then choose the offer that fits both your approval profile and your total-cost horizon.
Frequently Asked Questions
Does a 500 credit score guarantee FHA approval?
No. HUD’s 500–579 range limits the loan to 90% loan-to-value, and the lender must still underwrite income, debts, assets, property, occupancy, and its own overlays. The score rule sets a financing ceiling; it is not an approval promise.
Can an FHA Section 203 mortgage be used for any property?
Section 203 generally covers eligible one- to four-family primary residences, but county limits, unit count, condition, appraisal, and occupancy requirements apply. Ask the lender to confirm the specific property before making an offer.
Why do two lenders show different FHA or conventional costs?
Lenders can use different pricing, points, credits, overlays, underwriting paths, and rate-lock periods. Give both lenders identical purchase assumptions and compare the dated Loan Estimates line by line.
What does ‘conforming conventional’ mean?
It generally means a conventional loan that follows the eligibility and loan-limit rules associated with the major housing-finance agencies. The applicable county limit and the exact agency or product rules still need to be verified for your application.
