What Due Diligence Changes When You Buy a $1M+ Home in South Florida?

Buying a $1M+ home in South Florida adds due diligence that a typical purchase may never touch: getting insurance quotes before you are committed, checking flood zone and elevation, inspecting the seawall and dock on waterfront property, confirming roof age and impact protection, planning for jumbo financing and a possible appraisal gap, and reading the HOA and club membership terms line by line. If you plan to take title in an LLC or trust, that is a question for your attorney and tax advisor before you sign, not after.

Why should insurance come first, not last?

In Florida, the cost and availability of homeowners insurance can change the math on a home more than a few thousand dollars of price negotiation. At this price point it matters even more. Citizens Property Insurance, the state-backed insurer, generally cannot write homes with a dwelling replacement cost of $700,000 or more outside Miami-Dade and Monroe counties, so most $1M+ homes in Palm Beach County are insured in the private market. Proposals to raise that cap have been discussed in Tallahassee; check the current rule with your insurance agent.

What I tell buyers: ask an independent insurance agent for a quote during your inspection period, using the actual roof age, construction type and wind mitigation features of the home. A wind mitigation inspection documents roof shape, roof-to-wall connections and opening protection, which insurers use to price the windstorm part of the policy. For older homes, an insurer may also ask for a 4-point inspection. More on this in property insurance for Palm Beach County buyers.

What should you check about flood zone and elevation?

Flood risk is separate from windstorm risk, and standard homeowners policies do not cover flood. Look at three things:

Even outside a required zone, I suggest getting a flood quote. On waterfront and low-lying lots it is often affordable peace of mind.

What changes if the home is on the water?

Waterfront due diligence is its own project. The seawall, the dock, any boat lift, water depth at low tide, and the route to the ocean (including fixed bridges) all need checking by the right specialists, often a marine contractor in addition to your home inspector. Ask for permits on dock and seawall work, because unpermitted marine work can become your problem. I go through the full list in what to check before buying a waterfront home in Palm Beach County.

How much does roof age and construction matter?

A lot. Roof age drives both insurability and price. Ask for the roof permit date, the roofing material (tile, metal or shingle), and whether there are open permits. Impact windows and doors, a whole-home generator, and the condition of the AC systems are big-ticket items worth confirming. CBS construction, elevation and the age of major systems should all be on your inspection list. On large homes, budget for specialty inspections: pool and spa, generator, elevator, and sometimes a stucco or moisture check.

Steve, our Broker, spent 17 years in commercial construction project management before real estate. That background is why our team asks two questions about every major system: when was it done, and was it permitted? Whether it was done is not enough.

How do jumbo loans and appraisal gaps work at this price?

Any loan above the conforming limit is a jumbo loan. For 2026, the FHFA baseline conforming loan limit for a one-unit home is $832,750 in most of the country; your lender will confirm the limit that applies to your county. Jumbo lenders often ask for larger down payments, more cash reserves and more documentation, so start pre-approval early.

Appraisals are the other risk. Luxury homes have fewer comparable sales, so an appraisal can come in below the contract price. That difference is the appraisal gap, and you need a plan for it before you write the offer. As a simple example: if you agree to $1,500,000 and the home appraises at $1,450,000, the lender bases the loan on the lower number, and the $50,000 difference has to be covered by more cash, a renegotiated price, or the appraisal contingency in your contract. Your agent and lender should talk through which of those you are prepared to do.

What should you read in the HOA and club documents?

Many luxury homes in Palm Beach County sit inside HOA communities, and many are tied to golf or country clubs. Before your deadlines pass, read:

Membership rules vary a great deal. At PGA National, for example, club membership is optional. In other communities it comes with the home. Ask for the club's current documents directly rather than relying on a listing remark.

Should you buy in an LLC or a trust?

Some buyers want to take title in an LLC or a revocable trust for privacy, estate planning or liability reasons. Each choice can affect financing, homestead exemption, title insurance and taxes, and some communities have rules about entity ownership. This is a question for a Florida real estate attorney and your tax advisor, and it should be settled before the contract is signed so your offer names the correct buyer.

Once you are under contract, the rest of the process follows a timeline of deposits, inspections, financing and closing. Here is what happens after your offer is accepted in Florida.

Where should you start?

If you are planning a $1M+ purchase in Palm Beach Gardens, Jupiter or anywhere in Palm Beach or Martin County, I can help you set up the inspections, quotes and document reviews in the right order so nothing waits until the last week. Book a buyer consultation or call me at 561-352-3056.

Frequently Asked Questions

Can I get Citizens insurance on a $1M+ home in Palm Beach County?

Generally not. Citizens cannot write homes with a dwelling replacement cost of $700,000 or more outside Miami-Dade and Monroe counties, so most luxury homes are insured privately. Confirm the current rule with an insurance agent.

What is an appraisal gap?

It is the difference between the contract price and a lower appraised value. A financed buyer covers it with more cash, a renegotiated price, or by using the appraisal contingency in the contract.

When is a loan considered jumbo?

When it exceeds the conforming loan limit. FHFA set the 2026 baseline limit for a one-unit home at $832,750 in most of the country, and your lender will confirm the limit for your county.

Do Florida sellers have to disclose flooding?

Yes. Since October 1, 2024, sellers of residential property must give a flood disclosure before the contract is signed, including past flood insurance claims and federal flood assistance.

Should I buy my Florida home in an LLC or trust?

It depends on your financing, homestead, tax and estate goals. Ask a Florida real estate attorney and your tax advisor before you sign the contract.
