FHA vs. Conventional Loans: A First-Time Buyer's Guide

If your credit score sits below 620, choose an FHA loan — it accepts a 580 score with 3.5% down and is your realistic route to approval (Compass). If it clears 620, choose conventional — it starts at 3% down and its private mortgage insurance (PMI) cancels at 20% equity, while FHA's mortgage insurance (MIP) can stay for the life of the loan (Channing).

As a branch manager who has walked Michigan buyers through both programs, I've seen the decision turn on two numbers: the credit score and the down payment you can actually put together. The tables below lay out how each loan stacks up on credit, cost, and property standards.

FHA vs. Conventional at a Glance

The table below lays out the four numbers that determine which loan you can actually get, and which one will cost less over time. Use it as a quick reference, then read the sections below for the context behind each row.

Here is the rule of thumb I give every client: your credit score is the deciding factor. Under 620, FHA is your realistic route to approval. At 620 and above, run the numbers on conventional — the insurance that disappears after a decade of payments is the single biggest long-term difference.

Conventional Loans: The Strong-Credit Route

A conventional loan is a mortgage not backed by a government agency — it's underwritten to standards set by Fannie Mae and Freddie Mac, the two companies that buy most conforming mortgages from lenders. Because there's no government insurance cushioning the risk, lenders demand a stronger borrower profile: a minimum 620 credit score and enough income to keep your debt-to-income ratio in line (Mortgages by Channing).

The down payment barrier you've probably heard about — 20% — is a myth for first-time buyers. Fannie Mae's HomeReady and Freddie Mac's Home Possible programs let qualified buyers put down just 3% with reduced PMI rates, though both cap qualifying income at 80% of the area median income for the property's location (Channing). Fannie Mae's Standard 97 program also offers 3% down with no income limit, but it requires at least one borrower to be a first-time buyer and a homeownership education course (Gustan Cho).

Bottom line: if your credit clears 620 and your income fits the program caps, conventional's 3% down plus cancellable PMI beats FHA's 3.5% down plus life-of-loan MIP on total cost over the life of the mortgage.

FHA Loans: The Lower-Credit Door

An FHA loan is a mortgage insured by the Federal Housing Administration, a division of the U.S. Department of Housing and Urban Development. The FHA doesn't lend you the money — it insures the loan so approved lenders will take on borrowers who don't clear conventional standards (Compass). That government backing is what opens the door to a 580 credit score with just 3.5% down, and even scores as low as 500 can qualify with 10% down.

FHA is built for the two barriers that stop first-time buyers most often: limited savings and thinner credit. The entire 3.5% down payment can come from a gift from a family member, with a signed gift letter and a clean paper trail (McGowan). And where conventional underwriting caps debt-to-income near 45%, FHA routinely approves files at 43% and higher when the borrower shows compensating factors like cash reserves or a stable work history (Lower).

Bottom line: FHA is your approval route when credit is below 620 or savings are thin — accept the life-of-loan MIP as the price of getting in now, and refinance to conventional once your equity and credit improve.

The Hidden Cost: Mortgage Insurance Compared

Mortgage insurance is where the two loans diverge most sharply — and it's the cost most first-time buyers don't see coming. Because both loans let you buy with a tiny down payment, both require you to pay for insurance that protects the lender if you default. The difference is how long you pay it — and whether you can ever stop. FHA's MIP is removable only by refinancing, so a buyer who builds equity and raises their credit can escape it by moving to conventional later.

On an FHA loan, you pay two premiums: an upfront MIP of 1.75% of the loan amount (typically financed into the mortgage) plus an annual MIP paid monthly, and on most FHA loans today the annual premium stays for the life of the loan unless you refinance (Compass). On a conventional loan, private mortgage insurance cancels automatically once you reach 20% equity — typically seven to ten years into the mortgage (Channing).

The dollar gap is significant. A conventional 3% down loan on a $300,000 home with a 700 credit score carries roughly $125 a month in reduced PMI that eventually disappears, while the same home on FHA costs about $133 a month in MIP that never goes away — pushing total mortgage insurance over 30 years from roughly $12,000 to about $52,000 (Channing). Those are illustrative figures that vary by lender and credit profile, but the structure is the point: FHA's insurance compounds over decades; conventional's ends.

Property Standards: What the Appraiser Looks For

The house itself can decide your loan type. FHA carries stricter property requirements, because the FHA wants to protect against borrowers defaulting on a home with serious safety or structural problems. The appraisal focuses on safety, soundness, and security — meaning the home must be livable and structurally safe, and it must be your primary residence within 60 days of closing (Compass).

Conventional loans take a more flexible view of the property. Their appraisals still check value and condition, but they're less rigid about safety defects — a conventional loan can finance homes with fixable issues that would fail an FHA appraisal. Conventional loans also open the door to second homes and investment properties, which FHA does not allow (Compass). If you're eyeing a fixer-upper or a home with cosmetic damage, this is a real point in conventional's favor.

Choose FHA if... / Choose Conventional if...

Choose FHA if your credit score sits below 620, you have limited savings for a down payment, or your down payment will come entirely from a family gift. FHA is also the stronger pick when your debt-to-income ratio runs high but your other signs — steady employment, cash reserves — are strong. The trade-off you accept is a mortgage insurance premium that may follow you for the life of the loan.

Choose conventional if your credit clears 620 and your income fits the 3% down program caps (or you can put 5% or more down). The 3% down programs like HomeReady and Home Possible pair a small down payment with reduced PMI that cancels at 20% equity — a combination that saves tens of thousands of dollars over 30 years (Channing).

Either loan can get you into a first home. The number that matters is where you stand today on credit, savings, and income — and the honest conversation to have with your loan officer is about which of the two gets you the best monthly payment now without costing you a fortune over the decades.
