The quick answer

A one-time-close loan combines construction and permanent financing in one closing. A two-closing structure uses an interim construction loan and a separate permanent mortgage after the home is completed. One closing can reduce duplicate steps and establish permanent terms earlier; two closings can offer flexibility but introduce a second approval, closing and rate decision.

How a single closing works

The borrower closes before construction, and proceeds are disbursed through draws. After completion and required documentation, the loan converts or modifies into permanent financing under the program’s terms.

Fannie Mae describes single-closing construction-to-permanent financing, but individual lenders decide whether and how they offer it.

How two closings work

The first loan funds construction. When the home is complete, a second transaction pays off or replaces that interim financing with a permanent mortgage. The second loan may require updated income, assets, credit, appraisal, title and insurance documentation.

The borrower bears the risk that finances, property value, rates or program availability differ at the second closing.

Compare the tradeoffs

Do not assume one closing is always cheaper or two closings always more flexible. Compare written estimates and actual program mechanics.

  • Number of closing events and potential duplicate costs
  • When the permanent rate is established
  • Whether requalification is required
  • Flexibility to change the permanent loan
  • How overruns and change orders are handled
  • Construction-period payments and reserves

Example

A St. Johns County borrower expecting a 12-month custom build may value fixing the permanent structure at the outset. Another borrower may accept a separate permanent closing to preserve product flexibility. The better choice depends on risk tolerance, cost and lender terms—not the closing count alone.

Questions for the lender and builder

Borrowers should also obtain property-specific insurance, tax, HOA and CDD estimates for the completed home.

  • Who approves and controls draws?
  • What happens if completion is delayed?
  • Can the permanent terms change?
  • Is a float-down available?
  • What must be documented at completion?
  • Who covers overruns?
