No permanent conversion.

Who lends

Hard money and private lenders.

Equity required

The lower governs.

Underwriting the builder

The builder is the borrower in every practical sense.

Underwriting the project

Lenders want margin between cost and value.

Thin margins are declined.

Interest reserve

Most spec loans include a reserve to pay interest during the build.

It adds to the loan and reduces the cash the builder needs monthly.

Runs out if the build or the sale runs long.

Then the builder pays from cash.

Size it to a conservative timeline.

The carry

Interest, taxes, insurance, utilities and maintenance from completion until sale.

See our guide to Florida homeowners insurance cost.

A finished home that sits for months erodes the margin.

Price to sell at completion.

The carry is where spec projects fail.

Presales

A buyer under contract before completion turns a spec into a presale and lowers the lender's risk.

See our guide to new construction mortgages in Florida.

Deposits held in escrow under Florida law.

Some lenders require one presale before funding a second spec.

Taxes

A spec home is inventory; the sale is ordinary income for a builder.

Holding it as a rental changes the treatment.

A CPA structures the entity.

See our guide to LLC mortgages in Florida.

Budget discipline

A spec budget with a thin contingency is where projects turn.

Material price swings in South Florida have been sharp.

Fixed-price subcontracts where possible.

Track the budget against draws weekly.

The lender's inspector will; be ahead of them.

Reading the term sheet

Loan-to-cost, loan-to-value, rate, points, interest reserve, term, extension fees and release terms.

Ask what happens at maturity if the home is unsold.

Extension pricing decides whether a slow sale is survivable.

Personal guarantee language should be read by counsel.

The term sheet is the deal; the pitch is not.

Where to start

Assemble the licence, financials, prior projects, plans and budget.

Get comparable sales that support the finished value with margin.

Then start a conversation and we will match the project to a bank or hard money spec lender.
