In short
A jumbo loan is any mortgage above the conforming limit — $832,750 for a one-unit home in most counties in 2026, up to $1,249,125 in high-cost areas and $1,873,675 in Alaska and Hawaii. Jumbo loans need stronger credit, 10–20% down and reserves; when a loan is only slightly over the limit, a conforming first mortgage plus a piggyback second, or a bigger down payment, can be cheaper — compare the monthly payments with real rate quotes.
Who this is for: US buyers in high-price markets whose loan is near or above the conforming limit.
2026 conforming loan limits and jumbo loans
- Baseline: $832,750 for a one-unit home in most of the country (up 5.2% from $806,500). High-cost counties (parts of California, New York, DC, Colorado, Washington, Massachusetts and others) go up to $1,249,125; Alaska, Hawaii, Guam and the USVI start at $1,249,125 with a $1,873,675 ceiling.
- Jumbo = anything above your county limit. Expect 10–20% down, a 700–720+ credit score, DTI under 43–45% and 6–12 months of reserves.
- Three ways to handle a loan just over the limit: take the jumbo, split it into a conforming first plus a second mortgage or HELOC, or raise the down payment to the limit.
- Rates: jumbo pricing swings relative to conforming; when jumbo rates are lower (as they often were in 2025), a single jumbo loan can beat the piggyback structure outright.
- Limits are set each November from FHFA's house-price index and apply to loans delivered from 1 January.

Assumptions
- Limit = county figure entered, else the 2026 baseline, high-cost ceiling or AK/HI baseline.
- Option B splits the loan at the limit with the second at the piggyback rate; all loans 30-year fixed.
- Interest difference = total 30-year payments of A minus B.
Worked example
Loan $880,000 — $47,250 over the $832,750 limit. A: one jumbo loan at 6.45% = $5,533 a month. B: $832,750 conforming at 6.25% ($5,127) plus $47,250 at 8.5% ($363) = $5,491 a month — $43 less, and about $15,300 less interest over 30 years. C: putting $267,250 down (24.3%) keeps a single conforming loan at $5,127. Here the piggyback wins on payment; if the jumbo rate were 6.25% or lower, the single loan would win.
Frequently asked questions
What is the conforming loan limit for 2026?
$832,750 for one-unit homes in most counties; up to $1,249,125 in high-cost counties and $1,873,675 in Alaska and Hawaii.
Is a jumbo loan more expensive?
Not necessarily — jumbo rates have recently matched or beaten conforming rates for borrowers with strong credit, but qualification is stricter.
What is an 80/10/10 loan?
An 80% conforming first mortgage, a 10% second mortgage and 10% down — it avoids PMI and keeps the first loan under the limit.
Do limits differ for 2–4 units?
Yes — multi-unit conforming limits are higher ($1,066,250 for two units, and more for three and four).
Can I refinance a jumbo into a conforming loan later?
Yes, once your balance falls to the conforming limit through paydown or a limit increase — a common strategy as limits rise each year.
Do jumbo loans require reserves?
Usually 6–12 months of payments in liquid assets, more for very large loans or investment properties.
