What makes a mortgage "jumbo"

A jumbo loan is any mortgage above the conforming loan limit set annually by the FHFA. For 2026, the baseline conforming limit is $832,750 in most counties, rising to as much as $1,249,125 in high-cost areas like parts of California, New York, and Hawaii.

Jumbo threshold check: if your loan amount exceeds the conforming limit for your county, you need jumbo financing, which is not eligible for purchase by Fannie Mae or Freddie Mac and follows different underwriting rules.

How jumbo loans differ from conforming loans

Jumbo loans typically require higher credit scores (often 700+, sometimes 720+), larger down payments (often 10-20% minimum, though some lenders now offer less), more cash reserves, and historically carried higher rates — though the rate gap has narrowed significantly in recent years and jumbo rates are sometimes competitive with or even below conforming rates.

Down payment expectations

While conforming loans can go as low as 3-5% down, most jumbo lenders require at least 10-20% down, with the best rates typically reserved for 20%+ down payments. Some private banking relationships offer more flexible jumbo terms for well-qualified borrowers.

Frequently asked questions

What is the jumbo loan limit in 2026?
The baseline conforming limit is $832,750 in most US counties. Any loan above this amount is jumbo. High-cost areas have higher limits, up to $1,249,125 in the most expensive counties.
Do jumbo loans have higher interest rates?
Historically yes, but the gap has narrowed significantly. In 2026, jumbo rates are often comparable to or only slightly above conforming rates, particularly for well-qualified borrowers with strong credit and larger down payments.
How much down payment do I need for a jumbo loan?
Most lenders require at least 10-20% down, with the best rates reserved for 20%+ down payments. This is notably higher than the 3-5% minimums available on many conforming loans.
What credit score do I need for a jumbo loan?
Typically 700 or higher, with many lenders preferring 720+. Jumbo underwriting is generally stricter than conforming loans since these loans cannot be sold to Fannie Mae or Freddie Mac.
Can I avoid jumbo financing on an expensive home?
Some buyers use a "piggyback" structure — a conforming first mortgage plus a second loan or larger down payment — to keep the primary loan under the conforming limit, though this adds complexity and is less common than it once was.
