The Quick Read: Both loans check the same five things: credit, income against debt, down payment, the property, and your paperwork. They differ in how much room each one gives you. FHA is built for buyers with thinner credit or smaller savings, and it allows more flexibility on debt. Conventional loans reward stronger files, and their mortgage insurance can be cancelled later. Every figure here is subject to lender guidelines and full file review, and none of it is a commitment to lend.
Key Takeaways
- FHA allows up to 96.5% financing with a 3.5% minimum investment, starting at a 580 decision score.
- Debt-to-income limits start at 31/43 for FHA and stretch to 40/50 with documented strengths.
- Conventional loans lean on an automated underwriting finding, and the loan can often be priced without FHA’s permanent insurance.
- FHA is for a home you live in. Occupancy decides the leverage on any loan.
- Lenders can set rules stricter than the program minimums. That is why two lenders can give two answers.
Key Terms Defined
Decision credit score: the single score an underwriter uses after looking at every borrower on the loan.
Debt-to-income ratio (DTI): your monthly debt payments divided by your gross monthly income, before taxes.
Front-end ratio: the housing payment alone, as a percentage of gross income.
Back-end ratio: the housing payment plus all other monthly debts, as a percentage of gross income.
Minimum required investment: the cash you must put into the purchase from your own funds, as FHA defines it.
Mortgage insurance: protection for the lender, paid by you, that lets you buy with less than 20% down. The exact numbers vary by lender and program and follow a full review of property, leverage, and credit.
Compensating factor: a documented strength, such as cash reserves, that offsets a weak spot in the file.
Overlay: a lender rule stricter than the program’s published minimum.

How Do the Two Loans Compare at a Glance?
Here is the side-by-side. Each row gets unpacked below.
| Factor | FHA | Conventional |
|---|---|---|
| Max financing | 96.5% | Varies by lender and finding |
| Credit | 580+ through Lendmire’s lenders | Set by lender and automated finding |
| Debt ratios | 31/43 base, up to 40/50 | Total DTI up to 50% via automation |
| Mortgage insurance | Upfront plus annual | PMI, cancellable |
| Occupancy | Principal residence only | Varies by occupancy type |
| Loan limits | County limits apply | County limits apply, usually higher |
Notice that the conventional column has fewer fixed numbers. That is not an oversight. Conventional approval leans on an automated finding, which weighs your whole file at once.
What Does FHA Ask of You?
FHA asks for a 580 decision score, a 3.5% minimum investment, and debt ratios that fit the program’s limits. Across the wholesale programs Lendmire places files with, 580 is the working floor. These FHA loan programs allow up to 96.5% financing on a one- to four-unit home you will live in.
Here is how the pieces fit.
Credit. HUD has a lower tier for scores of 500 to 579, which needs 10% down. The lenders Lendmire works with do not reach below 580. A buyer under that line needs to build the score first. Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
Down payment. The 3.5% is measured against the lesser of the price or the appraised value. Gift funds can help cover it. Seller or interested-party contributions can go up to 6% of the price.
Ratios. The base pair is 31/43. The first number is the housing payment against income. The second is every monthly debt against income. With no compensating factors, that is the ceiling. Documented strengths, such as real reserves or a long, stable job history, can lift the top tier to 40/50.
The automated finding. FHA files run through HUD’s TOTAL Scorecard, which returns Accept or Refer. An Accept means FHA will insure the loan without a manual review, unless a manual downgrade applies. A Refer sends the file to a human underwriter. In practice the automated finding governs most files, and manual review handles the rest.
Mortgage insurance. FHA charges an upfront premium of 1.75% of the base loan, which is financed into the loan. It also charges an annual premium between 0.15% and 0.75% of the balance, depending on term, loan amount, and LTV. That is the program’s mechanics, not a quote. LTV, or loan-to-value, is the loan balance divided by the home’s value.
What Does Conventional Ask of You?
A conventional loan asks for a file strong enough to pass an automated review, usually with a mid-range credit score or better, steady income, and manageable debt. The bar is set by the lender and by the finding, not by a single published score.
Fannie Mae’s Selling Guide lays out the debt limits. In its guidance on debt-to-income ratios, a manually underwritten loan tops out at 36% total DTI. That can stretch to 45% when you meet the credit score and reserve requirements. Loans run through Desktop Underwriter, Fannie Mae’s automated system, can reach 50%. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
Three practical points follow:
- Credit matters more at the margin. A thin file that FHA accepts may get a weaker finding on a conventional loan.
- Down payment is flexible. You do not need 20% down. Putting down less simply means mortgage insurance.
- Strong files get rewarded. Higher scores and larger down payments mean less cost for the insurance. Leverage, reserves, and pricing vary by lender and program; the final terms follow the full file review.
How Do Lenders Calculate Debt-to-Income?
Lenders divide your monthly debts by your gross monthly income, which is the pay before taxes. The CFPB’s definition is the same one both programs start from, and it notes that limits differ by product and lender.
Here is the mechanic, using percentages instead of dollars. Picture gross income as 100%.
1. Add the proposed housing payment: principal, interest, taxes, insurance, and any mortgage insurance or HOA dues. Say it equals 28% of income.
2. Add your other monthly debts: car loan, student loan minimums, credit card minimums. Say they total 12%.
3. Front-end ratio: 28%. Back-end ratio: 40%. Written as a pair, that is 28/40.
That file clears FHA’s base 31/43 pair. On a conventional loan, the 40% back-end sits above the 36% manual limit. It would need the higher 45% tier, which depends on credit score and reserves, or an automated approval, which can reach 50%.
Now add a new car loan during the process. If the other debts jump from 12% to 18%, the back-end lands at 46%. That is past the base FHA pair and past the manual conventional limit. The file might still work with compensating factors or an automated approval. But it now needs help.
Which debts count? Anything with a required monthly payment on your credit report. Utilities and groceries do not count. A debt with only a few payments left can sometimes be handled differently, depending on the lender.
What Documents Will You Need?
Both loans verify the same things: who you are, what you earn, what you own, and what you owe. Lenders ask for pay stubs, traditional personal-income documentation, bank statements, and ID. They also ask for a history of your employment and an explanation for any large deposits.
Two points trip people up:
- Large deposits. Money that appears from nowhere needs a paper trail. Gift funds need a gift letter and proof of transfer.
- Self-employment. Income is usually averaged from traditional personal-income documentation, after business deductions. Lendmire’s piece FHA vs Conventional for a Self-Employed Buyer walks through how that changes the math.
The Loan Estimate you receive after applying shows the terms. Compare it to the Closing Disclosure you receive before closing. Differences should be explainable.
What Are the Property and Occupancy Rules?
FHA is for your own home. At least one borrower must move in as a principal residence within 60 days of signing, and must intend to stay for at least one year, per HUD’s owner-occupant definition. The property can be one to four units, provided you live in one of them.
The home also has to be in decent shape. HUD’s standard is that it must be safe, sound, and secure. An appraiser checks that along with value. A leaking roof, peeling paint on an older home, or a missing handrail can all become repair conditions.
Conventional loans are more flexible on condition. They still require an appraisal. They are also not limited to a primary residence. If your plan involves a second home or a rental, occupancy decides how much leverage a lender allows. That is a different conversation from the one here.
Loan limits matter too. Both programs set limits by county, and they change every year. FHA’s limits sit below conventional limits in most counties. A buyer in a high-cost county who needs a large loan may find that conventional or jumbo financing is the only fit.
FHA Mortgage Insurance vs. PMI
The biggest difference over time is how the insurance ends. FHA’s annual premium lasts for the loan term when you start above 90% LTV on a thirty-year loan. At or below 90% LTV, it ends after eleven years. The upfront 1.75% is paid at the start and financed in. Terms vary by lender guidelines, property type, leverage, credit profile, and full file review.
Conventional PMI works differently. Per the CFPB’s guidance on removing PMI, you can ask to cancel when your balance reaches 80% of the original value. That takes a written request, a good payment history, no junior liens, and evidence the value has not dropped. Servicers must generally end it automatically when the scheduled balance reaches 78%.
So the question is not which loan has insurance, since both do. The question is which one you can shed. A buyer who plans to stay long term should weigh that carefully. A buyer who expects to refinance within a few years may weigh it less.
Where the General Rules Break
The numbers above hold for most files. Here is where they bend.
No credit score. Some buyers have no usable score. HUD’s manual underwriting guidance puts borrowers with no score, or a score of 500 to 579, on the 31/43 manual ratios. The lenders Lendmire places with start at 580 regardless. With no score, only income from borrowers who live in the home and sign the note counts.
A co-borrower who won’t live there. FHA allows a non-occupant co-borrower. Conventional rules usually tighten the ratio for the occupying borrower in that case. The exact limit depends on the lender.
Recent credit events. HUD’s waiting periods are two years from a chapter 7 discharge and three years from a foreclosure. Those are HUD’s rules, not a promise about any particular lender’s file. Some lenders wait longer.
Energy-efficient homes. HUD’s guidelines allow stretch ratios of 33/45 for energy-efficient homes. That is a HUD rule, and lender guidelines decide whether it applies.
Stricter lenders. HUD sets the floor, not the ceiling. Some lenders set a higher credit minimum than the program requires. This is why one buyer gets a yes in one place and a no in another.
Refinancing later. FHA is not a life sentence. An FHA Streamline refinances an existing FHA loan with no appraisal and a limited credit review. It needs a net tangible benefit, and the premium continues. An FHA rate-and-term refinance with an appraisal reaches 97.75% on a home you have lived in for the previous twelve months. An FHA cash-out reaches 80% LTV after twelve months of owning and occupying it. Moving from FHA to conventional means a new loan with its own qualification. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Which Loan Fits Which Buyer?
Think in profiles, not in rankings.
The lower-credit buyer. Score just above 580, modest savings, steady job. FHA usually fits better here. The 3.5% minimum and the flexible ratios give room that a conventional finding may not.
The strong-credit, low-savings buyer. A high score and little cash. Conventional may bring a smaller insurance bill and cancellation later. FHA may still work if the down payment is the sticking point. Compare the two on the Loan Estimate.
The high-DTI buyer. Debts are heavy relative to income. Here FHA’s ratio structure helps, since documented factors can lift the pair to 40/50. A conventional file would need a strong automated finding to reach 50%.
The veteran. Eligible veterans have a third option that can beat both. Lendmire’s piece VA vs Conventional vs FHA Loan for a Veteran Buying a First Home covers that comparison.
The FHA-versus-conventional choice is a genuine toss-up for many mid-range buyers. The monthly cost can look similar early on. The difference shows up in how long the insurance sticks around.
How Does the Process Run, Step by Step?
1. Application. You give the lender income, asset, employment, and debt information. You receive a Loan Estimate.
2. Credit pull. The lender finds your decision credit score.
3. Automated underwriting. FHA files run through TOTAL. Conventional files run through an automated system like Desktop Underwriter.
4. Manual review, if needed. FHA sends Refer findings to a human underwriter. Strong compensating factors matter most here.
5. Appraisal. The appraiser confirms value and, for FHA, that the home meets minimum property standards.
6. Insurance set-up. FHA gets its upfront and annual premiums. Conventional gets PMI if you put down less than 20%.
7. Closing. Compare the Closing Disclosure to your Loan Estimate before you sign.
Between steps 1 and 7, do not change anything. A new car loan, a job change, or an unexplained deposit can reopen the file. Skip the financing on that new couch too.
What If You Don’t Qualify Yet?
Falling short is usually fixable, and the fixes are specific.
- Score under 580. Pay down revolving balances and correct errors on your report. Then wait for the score to update.
- DTI too high. Pay off small installment loans or lower card balances. Each removed payment helps the back-end ratio.
- Not enough cash. Look at gift funds and seller contributions, which can go up to 6% of the price on FHA.
- Recent credit event. Check HUD’s waiting periods against your discharge or foreclosure date.

Frequently Asked Questions
Which is easier to qualify for, FHA or conventional?
For buyers with thinner credit or smaller savings, FHA is usually easier. It starts at a 580 decision score with a 3.5% minimum investment, and its ratio structure leaves room for documented strengths. Conventional can be easier for strong files because it can cost less over time. Lender guidelines and the automated finding decide the outcome.
Do I need 20% down for a conventional loan?
No. Putting down less than 20% is common. The tradeoff is private mortgage insurance, which you can ask to cancel at 80% of the original value, subject to conditions. Servicers must generally end it automatically at 78%.
Can I use FHA for a second home or rental?
Not as a stand-alone property. FHA is for a principal residence you occupy. A multi-unit property works if you live in one of the units.
Can I switch from FHA to conventional later?
Yes, by refinancing into a new loan. That new loan has to qualify on its own: credit, income, DTI, and equity. Some borrowers do this to end FHA’s annual premium. The right timing depends on your balance, your value, and your score.
Why do different sources give different DTI numbers?
They are describing different paths. Automated approvals, manual underwriting, and lender overlays each use different limits. Some sources also quote front-end ratios and others quote back-end. Always check which ratio and which path a number refers to.
