Construction Loans: A Complete Guide

A construction loan is a short-term loan used to finance the building of a home or other real estate project. These specialized loans typically have variable rates and convert to permanent mortgages once construction is complete. Our construction loan calculator helps you estimate all costs associated with your building project.

How Construction Loans Work:

  1. Short-term financing: Typically 6-18 months during construction
  2. Interest-only payments: You pay only interest during construction
  3. Draw schedule: Funds are released in stages as construction progresses
  4. Conversion: Loan converts to a traditional mortgage after completion

Key Features of Construction Loans:

  • • Higher interest rates than traditional mortgages
  • • Typically require 20-30% down payment
  • • Require detailed construction plans and budget
  • • Lender inspects progress before releasing funds
  • • May require builder approval
  • • Shorter approval timeline than traditional loans

Types of Construction Loans:

Construction-to-Permanent

Converts automatically to a mortgage after construction. One closing, lower fees.

Stand-Alone Construction

Requires separate permanent financing. Two closings, more paperwork.

Renovation Loans

For major renovations on existing properties. Similar structure.

Owner-Builder Loans

For homeowners acting as their own general contractor. Higher requirements.
