Jumbo Mortgage Loans: High-Balance Financing
Buying higher-end real estate in Florida often means going past the standard conforming loan limit. A jumbo loan doesn't always mean 20% down. Here's how jumbo underwriting, cash reserves and 10% down options actually work.
When does my loan become a jumbo?
What makes it a jumbo?
A Jumbo loan is simply any mortgage where the loan amount is higher than the standard FHFA county conforming limits.
Do I really need 20 percent?
You don't need 20% down to buy a luxury home. We have access to elite Jumbo portfolios that allow as little as 10% down.
How much do I need in reserves?
The biggest hurdle for Jumbo buyers is post-closing liquidity. You must prove you have 6 to 12 months of mortgage payments left in the bank.
What score do I need?
Because these loans carry high financial risk for private investors, most programs require a pristine credit history and a 700+ FICO score.
What actually makes a loan jumbo?
Every year, the Federal Housing Finance Agency (FHFA) sets a maximum "conforming loan limit" for every county in the United States. If your loan amount is under that limit, the loan can be sold to Fannie Mae or Freddie Mac. If you're buying a $1.5 million home and need to borrow $1.2 million, you have officially exceeded that county limit. Your loan is now considered "Non-Conforming" or Jumbo.
Who lends on jumbo loans?
Because Jumbo loans can't be sold to the government-sponsored agencies, they're held by private investors or massive portfolio banks. This means there is no single rulebook for Jumbo loans. Every investor sets their own guidelines. This is where a mortgage broker like AAA Capital Funding becomes invaluable. If one Jumbo investor denies your file due to a strict DTI overlay, we simply route the file to a different investor with looser guidelines.
Is 20 percent down really required?
A lot of buyers assume a jumbo purchase means selling investments to put 20% down. Twenty percent down usually gets the best pricing and avoids mortgage insurance, but it isn't a hard requirement.
Can I do 10 percent down?
For highly qualified borrowers (typically those with 720+ credit scores and strong income), we have access to Jumbo programs requiring only a 10% down payment. This allows you to keep hundreds of thousands of dollars in the market earning a return, rather than trapping it in the drywall of your house.
Will I pay PMI on a jumbo?
If you put less than 20% down, the investor will typically structure the loan in one of two ways to protect their risk: they will either use Lender-Paid Mortgage Insurance (LPMI) built into the interest rate, or they will structure a "Piggyback" loan (an 80% first mortgage combined with a 10% second mortgage) to completely avoid PMI altogether.
What usually kills a jumbo file?
Unlike standard Conventional or FHA loans, which rarely require you to have leftover cash after closing, Jumbo loans are obsessed with "post-closing liquidity." Because the monthly payments are massive, the investor wants a guarantee that a sudden job loss won't trigger an immediate default.
How are reserves calculated?
The underwriter will require you to prove you have a certain number of "months" of mortgage payments remaining in liquid assets. If your new Jumbo mortgage payment (Principal, Interest, Taxes, Insurance) is $8,000 a month, and the investor requires 12 months of reserves, you must prove you have $96,000 safely sitting in eligible accounts after you have paid your down payment and closing costs.
Eligible Reserve Accounts: You don't need to hold this in a standard checking account. Vested 401(k)s, IRAs, mutual funds, and publicly traded stocks can almost always be counted toward your reserve requirement (though retirement accounts may be hit with a 30% haircut to account for early withdrawal penalties).
