What is a conventional loan?

A conventional loan is a mortgage that isn't backed by the government. Most follow guidelines set by Fannie Mae and Freddie Mac, which buy mortgages from lenders. A loan that meets their guidelines and stays under their loan limit is called a conforming loan.

Because these loans are easy for lenders to sell, they often come with competitive rates, especially for borrowers with strong credit and a solid down payment.

What are the 2026 conforming loan limits?

For 2026, the baseline limit for a single-family home is $832,750, which applies to most Oregon counties. In a few designated high-cost areas around the country the limit can reach $1,249,125. If you need to borrow more, you'd typically use a jumbo loan.

What do you need to qualify?

RequirementTypical guideline
Credit score620 minimum; better pricing as your score rises
Down payment3% to 5% minimum, depending on the buyer and property
Debt-to-income ratioOften up to the mid-40s, sometimes higher with a strong file
IncomeSteady, documented income, usually with a two-year history

Guidelines vary by lender and your overall file.

How does PMI work on a conventional loan?

With less than 20% down you'll pay private mortgage insurance (PMI). It's priced on your whole file: credit score, down payment, debt-to-income ratio, and even the number of borrowers. With strong credit it's often lower than people expect. I recently had clients buy a home for about $540,000 with 10% down, and their PMI came to about $52 a month.

PMI is also priced in brackets. Putting 5% down and 7% down often cost the same, so if you put more down, it usually pays to reach the next bracket. More on choosing a down payment.

Benefits of a conventional loan

  • Lower cost with strong credit. Rates and PMI reward a stronger file.
  • PMI goes away. Unlike most FHA loans, conventional PMI ends once you build enough equity.
  • Flexible property use. Primary homes, second homes, and rental properties.
  • Term options. Fixed or adjustable rates, with terms commonly from 10 to 30 years.

Is a conventional loan right for you?

If you have a solid credit score and some savings, a conventional loan is often the most affordable way to buy. If your credit is still recovering, an FHA loan might have the lower payment. I run both side by side and let you decide.

Frequently asked questions

What credit score do you need for a conventional loan?

Usually at least 620. Pricing and mortgage insurance keep improving in steps as your score rises, up to about 780.

Can I get a conventional loan with less than 20% down?

Yes. Some buyers can put as little as 3% down, and 5% or 10% down is common. With less than 20% down you’ll pay private mortgage insurance (PMI) until you build enough equity.

What is the 2026 conforming loan limit in Oregon?

For a single-family home, the baseline limit is $832,750 in most Oregon counties, including Multnomah, Washington, and Clackamas. Above that, you’d typically need a jumbo loan.

When does PMI go away on a conventional loan?

You can ask to remove it once your loan balance reaches 80% of the home’s original value, and it ends automatically at 78%. Rising home values can also let you remove it early with a new appraisal or a refinance.

Is conventional better than FHA?

It depends on your credit and debts. With strong credit, conventional usually wins. With a lower score, FHA can have the lower payment. Here’s how to compare them.
