Conventional Loan Requirements in 2026
Plain-English breakdown of what you usually need for a conventional mortgage in 2026: credit score, down payment, debt-to-income ratio, conforming loan limits, PMI, and the real-world reasons conventional financing can be a great fit — or the wrong fit.
Quick answer
A conventional loan is a mortgage that is not insured or guaranteed by the government. In 2026, many conventional borrowers will still need a 620+ credit score for common low-down-payment options, can sometimes buy with as little as 3% down, usually need PMI if they put less than 20% down, and must stay within the 2026 conforming loan limit of $832,750 in most counties unless they are in a high-cost area or using a jumbo loan. Your debt-to-income ratio matters too, and lower is better, even though some eligible files can stretch higher. Official sources: CFPB, FHFA, Fannie Mae, and Freddie Mac.

What a conventional loan is in plain English
A conventional loan is simply a mortgage that is not backed by a government program. That means it is not an FHA loan, not a VA loan, and not a USDA loan. The CFPB explains it that way directly. Conventional loans can be conforming or non-conforming. Conforming loans follow the size and underwriting rules used by Fannie Mae and Freddie Mac. Non-conforming loans go outside those rules, and the most common example is a jumbo loan.
Conventional = the standard mortgage lane. FHA = the government-backed lower-barrier lane. Conventional often costs less over time for stronger borrowers, but FHA can be easier to get when your credit score or down payment is weaker.
Conventional loan requirements in 2026
1) Credit score
There is not one magical universal number for every lender and every conventional product. But in real life, 620 is still the most important baseline to know. Fannie Mae’s general credit score rules still show a 620 minimum representative credit score in many standard cases, and Fannie Mae’s HomeReady consumer pages still show a 620 minimum credit score. That does not mean every 620 borrower gets the best deal. Higher scores usually mean better pricing, easier approval, and lower PMI costs.

2) Down payment
One of the biggest myths in housing is that you always need 20% down for a conventional loan. You do not. In 2026, some conventional programs still support 3% down for eligible borrowers. Fannie Mae HomeReady and Freddie Mac HomeOne / Home Possible are examples of low-down-payment conventional paths. But putting less than 20% down usually means private mortgage insurance (PMI), and it can tighten the approval math.
3) Debt-to-income ratio (DTI)
Your DTI is how much of your gross monthly income is already going toward debt payments. Fannie Mae’s selling guide says a manually underwritten loan that recalculates above 45% is not eligible for delivery, and a DU casefile above 50% is also not eligible. That does not mean 49.9% is comfortable. It just means some files can reach higher than the old-school “36% rule.” For normal people, lower DTI still gives you more breathing room and less risk of becoming house-poor.

4) Conforming loan limits
In most of the United States, the 2026 conforming loan limit for a one-unit property is $832,750. In high-cost areas, the one-unit limit can go up to $1,249,125. If your loan amount is above the limit for your county, you are usually moving into jumbo territory, which often means stricter approval and reserve expectations.
5) PMI if you put less than 20% down
On many conventional loans, putting less than 20% down means you will typically pay PMI. The upside versus FHA is that conventional PMI is usually removable. CFPB says borrowers on many covered mortgages can generally request cancellation at 80% of the home’s original value if current, and automatic termination generally happens at 78%. That removability is a big reason stronger borrowers often prefer conventional financing.
6) Property type and occupancy matter
Primary residences get the easiest path. Second homes and investment properties usually require more down, stronger credit, and sometimes more reserves. Low-down-payment conventional options are generally targeted toward principal residence buyers, not vacation homes.
7) Lender overlays are real
This is where a lot of buyers get confused. Fannie Mae or Freddie Mac may allow something on paper, but your actual lender may still want more. That can mean a higher minimum score, more reserves, lower DTI, or stronger documentation. So the “official rule” is only part of the story. Your lender’s overlay is the part that hits your actual approval.
| Requirement area | What to know in 2026 | Plain-English takeaway |
|---|---|---|
| Credit score | 620 is still a major baseline for many conventional options | 620 may open the door, but stronger scores usually improve rates and PMI |
| Down payment | As low as 3% is possible on some eligible programs | You do not always need 20% down, but less than 20% often means PMI |
| DTI | Some eligible files can go up to 50%, while lower is safer | Approval and comfort are not the same thing |
| Loan size | $832,750 baseline one-unit conforming limit in most counties | Above your county limit usually means jumbo rules |
| PMI | Typically required under 20% down on many conventional loans | Unlike FHA, conventional PMI may be removed later |
Who conventional loans are best for
Conventional usually makes more sense if…
- Your credit score is solid and improving.
- You can comfortably handle the payment without stretching your budget.
- You want the chance to remove PMI later.
- You are buying within conforming limits in your county.
- You want long-term cost efficiency more than easier short-term approval.
Conventional may be the wrong fit if…
- Your score is weak and FHA gives you a cleaner path.
- Your DTI is already tight and the approval is shaky.
- You have very little cash for closing and reserves.
- You are shopping above conforming limits and really need a jumbo comparison.
- You are trying to buy before your budget is actually ready.
Conventional vs. FHA in real life
The cleanest difference is this:
- FHA is often easier to qualify for if your credit or cash position is weaker.
- Conventional often costs less over time if your file is stronger.
- FHA mortgage insurance can stick around much longer depending on LTV and term.
- Conventional PMI is often removable, which matters a lot if you plan to stay in the home.
That is why a borrower with decent credit, a manageable DTI, and a real plan to build equity often ends up better off with conventional financing. But someone trying to get approved with a weaker file may find FHA gets them in the door sooner.

A normal-person example
Let’s say you are buying a $350,000 home.
The right answer is not automatically “buy with the lowest possible down payment.” The right answer is the one that leaves you with enough breathing room for maintenance, closing costs, moving costs, repairs, and life.
That is why I’d pair this page with the Cash to Close Calculator, Closing Costs Calculator, and Down Payment Calculator before choosing a loan type.
Common mistakes to avoid
- Thinking 20% down is always required. It is not.
- Thinking approval = affordability. A lender may approve more than your life can comfortably support.
- Ignoring PMI removal rules. Conventional PMI is a cost, but it is often not forever.
- Forgetting county loan limits. The payment may work, but your loan amount may still push you into jumbo rules.
- Shopping one lender only. Conventional pricing and overlays can vary.
- Looking only at principal and interest. Taxes, insurance, HOA, PMI, repairs, and cash-to-close matter too.
