Construction Loans Explained: How They Work in 2026

Everything you need to know about financing a new home build with a construction loan.

What Is a Construction Loan?

A construction loan is short-term financing specifically designed to cover the costs of building a new home or doing major renovations. Unlike a regular mortgage where you receive a lump sum, construction loans disburse funds in stages as building progresses.

Disbursement In “draws” as work completes
Interest Pay only on amount drawn
Rates 1-2% higher than mortgages
After construction Convert to mortgage or pay off

Construction-only Separate construction and mortgage Those wanting to shop rates later
