A high balance loan Florida buyers in Monroe County can use sits between the base conforming limit and the county ceiling. It keeps agency pricing where a jumbo would apply elsewhere.

A high balance loan Florida buyers can use exists only where the county loan limit exceeds the national base.

In Florida that is Monroe County. Everywhere else, the base limit is the line and above it is jumbo. Our jumbo page covers what sits above.

How the limits work

The FHFA sets a national base conforming limit each year.

High-cost counties get a higher ceiling, up to 150 percent of the base.

The FHFA publishes the limits by county.

Loans between the base and the county ceiling are high balance.

They still go to Fannie Mae and Freddie Mac.

Florida's map

Monroe County, the Keys, is Florida's only high-cost county.

See our guide to Florida Keys mortgages.

Miami-Dade, Broward and Palm Beach sit at the base limit.

A loan above the base in those counties is jumbo, not high balance.

That surprises buyers from California or New York.

Pricing

High balance loans carry an agency adjustment above base conforming.

They usually price below jumbo.

See our guide to jumbo versus conforming in Florida.

The gap moves with the market.

In some periods jumbo has priced lower.

Qualifying

Agency rules apply: automated underwriting, standard documentation.

See our guide to jumbo loan requirements in Florida for the contrast.

Down payment minimums are slightly higher than base conforming for some occupancy types.

Reserves may be required.

Credit score floors are the agency floors.

Down payment

As low as five percent on a primary residence for many high balance files.

Second homes and rentals require more.

See our guide to loan-to-value in Florida.

PMI applies above eighty percent.

Jumbo lenders often require more down.

Second homes in the Keys

Many Monroe County purchases are second homes.

See our guide to snowbird second home mortgages in Florida.

High balance second-home loans exist with a larger down payment.

Agency second-home pricing adjustments stack with the high balance adjustment.

Compare to jumbo carefully.

FHA high balance

FHA limits also rise in Monroe County.

See our guide to FHA loan limits in Florida.

The FHA ceiling is set separately from the conventional one.

Low down payment FHA on a Keys home is possible up to that limit.

Insurance premiums apply as usual.

VA loans

VA has no loan limit for borrowers with full entitlement.

See our guide to VA loan requirements in Florida.

County limits matter only for partial entitlement.

See our guide to VA second-tier entitlement in Florida.

A Keys purchase with full entitlement needs no down payment.

Piggybacks to stay conforming

A first mortgage at the base limit plus a second lien for the rest.

See our piggyback page.

This keeps base conforming pricing on the first.

It works in the tri-county area where no high balance tier exists.

Compare the blended rate to a jumbo quote.

Limits change yearly

The FHFA announces new limits each November for the following year.

Limits have risen most years with home prices.

A loan that is jumbo in December may be conforming in January.

Timing a closing around the change can save real money.

Ask what next year's limit will be.

Refinancing into conforming

A jumbo borrower whose balance has fallen below the limit can refinance into conforming.

See our guide to refinance break-even in Florida.

Appreciation and amortisation both help.

The pricing improvement can justify the closing costs.

Check the current limit against your balance.

Insurance in the Keys

Wind and flood insurance are expensive in Monroe County.

See our guide to flood insurance in Florida.

Both feed debt-to-income.

Get quotes before the appraisal.

A high premium can push a borderline file over the limit.

Property types

Stilt homes, canal-front lots and older construction are common in the Keys.

See our guide to wind mitigation inspections in Florida.

Agency appraisals require comparable sales, which can be scarce.

Unusual properties may end up in portfolio lending regardless of size.

See our guide to portfolio loans in Florida.

Comparing the three tiers

Base conforming: best pricing, lowest limits.

High balance: agency pricing with an adjustment, Monroe County only.

Jumbo: private pricing, no limit, stricter underwriting.

The right one is the cheapest one that fits the loan amount.

Ask for all three where they apply.

Appraisals at the top of the range

Higher-priced homes have fewer comparable sales.

See our guide to low appraisals in Florida.

A low appraisal can push the loan amount down or the down payment up.

Ask the agent for recent sales before the appraiser goes out.

Waterfront and view adjustments are where values diverge.

Reserves

High balance and jumbo files often require several months of payments in reserve after closing.

Retirement accounts count at a discount.

See our guide to large deposits and source of funds in Florida.

Document the accounts early.

Reserves can offset a higher debt-to-income ratio.

Where to start

Check the current conforming limit for the county where you are buying.

Compare your loan amount against the base and the county ceiling.

Then start a conversation and we will price the tier that applies.
