What is a construction loan?

A construction loan is short-term financing used to pay for building a project. The lender releases money in draws as work is completed, and the loan is usually repaid or converted to permanent financing when construction ends.

A construction loan pays for a building that does not exist yet. That is why it works differently from a mortgage. The lender approves a total amount based on the budget, plans, and borrower, then funds it in stages through construction draws as the work is verified. During construction the borrower usually pays interest only on the amount drawn so far.

Contractors are not usually the borrower, but the loan shapes their job. It sets the payment schedule, the paperwork required for each payment, and often how change orders get funded.

How a construction loan works on a real project

Say an owner builds a $2.2 million, 10,000-square-foot flex building. The lender approves a loan for part of the total project cost and requires the owner to put in equity first. The loan documents include:

  • A project budget with line items for hard costs, soft costs, and a contingency line.
  • A draw schedule and draw procedures, with lender inspections before each release.
  • Retainage or holdback on each draw, sometimes separate from what the construction contract holds.
  • Conditions: lien waivers with each draw, title updates, insurance certificates, and a completion date.
  • Takeout or conversion terms: when and how the loan is repaid or rolled into permanent financing.

Halfway through, the owner adds a mezzanine for $140,000. The lender will only fund it if the change is approved and the budget still balances. If the contingency line cannot cover it, the owner has to put in more cash before the lender funds the next draw. The contractor's change order is signed, but payment for it depends on the loan.

What contractors should check

  1. Ask whether the job is financed and who the lender is. It affects your lien rights and payment timing.
  2. Get the lender's budget and draw schedule and match your schedule of values to it.
  3. Confirm how change orders are approved and funded before you start change work.
  4. Learn what the lender requires with each draw: lien waivers, invoices, photos, stored material backup.
  5. Watch the lien priority rules in your state. A construction mortgage recorded before work begins can come ahead of mechanics liens in some states.

Common problems

The usual trouble is a loan that runs short. Overruns, owner changes, and interest costs eat the contingency, and the lender stops funding until the owner adds equity. Contractors who are not watching the loan balance find out when the draw gets denied. Asking the owner each month how much loan is left undrawn is a fair question, and a useful one.

Frequently asked questions

Who takes out a construction loan, the owner or the contractor?

Usually the owner or developer. Contractors may carry their own lines of credit for working capital, but the project loan belongs to the owner.

What is a construction-to-permanent loan?

A loan that funds construction and then converts to a long-term mortgage when the building is complete, often with a single closing.

Why do lenders inspect before each draw?

To confirm the work billed is actually in place, so the loan balance never gets ahead of the building's value.

What happens if the construction loan runs out?

The lender usually requires the owner to put in more equity before funding further draws. Work can stall until the gap is covered.
