Jumbo loans in Ohio and California — when the house is bigger than the limit.

Where the line sits in 2026

Fannie Mae and Freddie Mac buy loans up to the conforming limit; anything larger is a jumbo, funded and held by the lender or sold to private investors. That is why jumbo rules vary lender to lender: there is no single rulebook. The 2026 baseline limit is $832,750 for a one-unit home, up 3.26% from 2025, and high-cost counties in California go up to 150% of that, or $1,249,125.

Ohio: jumbo is the exception, not the rule

The Greater Cincinnati median sale price was $329,450 in July 2026. Even Mason, one of the region's priciest suburbs, carried a Zillow home value index of about $513,673 at the end of July 2026. With 20% down, a home has to cost more than roughly $1,040,000 before the loan crosses $832,750. In Cincinnati that is Indian Hill, the top of Hyde Park and Mount Lookout, and new construction in Mason and Loveland. In Columbus it is Dublin, New Albany and Upper Arlington; in Cleveland, Shaker Heights and Hunting Valley.

The practical point: an Ohio jumbo buyer usually has a choice. Put a little more down and stay conforming, or keep the cash and go jumbo. I price both. Sometimes the jumbo is cheaper; sometimes a slightly larger down payment saves a quarter point for thirty years.

California: jumbo is the market

The July 2026 California Association of Realtors medians tell the story. In Orange County, San Francisco and Santa Clara County, even a 20% down payment leaves a loan above the $1,249,125 ceiling. In Los Angeles County, 20% down on the median lands just under the ceiling as a high-balance conforming loan — but the neighborhoods people actually search in Pasadena, the South Bay and the Westside run well above the county median.

What jumbo underwriting actually looks at

Jumbo lenders are lending their own money, so they underwrite the borrower, not just the ratio. Expect these four things to matter more than on a conforming loan:

• Reserves. Six to twelve months of the full housing payment in liquid or retirement accounts after closing. This is the number that most often decides whether a jumbo file is easy or hard.
• Down payment. Ten to twenty percent. Twenty gets the best rate and the most lenders; ten is possible with strong credit and reserves, at a price.
• Credit. 700 or better for most programs; 740-plus for the sharpest pricing.
• Debt-to-income. Usually capped near 43%, with less flexibility than the automated conforming systems allow.

For self-employed borrowers whose tax returns understate what the business really earns, jumbo is where a bank statement loan shines: qualify on deposits, at jumbo loan sizes, without the write-off problem.

1. 1
   Day 1

   Structure conversation

   Price, down payment, reserves, credit. I map whether the loan is conforming, high-balance, or jumbo — and price all that apply.

2. 2
   Week 1

   Full documentation up front

   Two years of income, all asset statements, sourced large deposits. Jumbo underwriters read everything; a complete file closes fast.

3. 3
   Under contract

   Appraisal (sometimes two)

   Larger loans can require a second appraisal or a desk review. I order early so it never delays the closing date.

4. 4
   Closing

   Clear to close

   My closings average about 13 days from application on a complete file. Jumbo adds review, not weeks, when the package is right.

Jumbo, high-balance, or two loans?

Near the line, there are three ways to finance the same house, and the right one changes month to month:

1. One jumbo loan. Simplest. Best when jumbo pricing is competitive and you have the reserves.
2. A larger down payment to stay conforming. Best when the jumbo rate is meaningfully higher and you have the cash.
3. A conforming first plus a second mortgage. An 80% first at conforming pricing with a HELOC or fixed second covering the gap. Less common now, but it can beat both when jumbo pricing is wide.

I run all three on every file that sits within about $100,000 of the limit. It takes fifteen minutes and has saved buyers real money.
