HOME REMODEL FINANCING · UPDATED SEPTEMBER 2026

How can you pay for a remodel or ADU?

Start with one simple idea: the house may help you borrow, but every loan has a different rate, payment, fee structure and risk.

What is home equity?

Home equity is the part of the home you own after subtracting the mortgage balance from the estimated property value. Example: if a home is worth $1,000,000 and the mortgage balance is $600,000, the owner has about $400,000 in gross equity. A lender will not normally let you borrow all of it.

Home equity loan

A home equity loan is usually a second loan secured by the house. You receive one lump sum and make regular payments. It may have a fixed rate, but interest normally begins on the full amount immediately.

What is a HELOC or home credit line?

HELOC means Home Equity Line of Credit. Think of it as a credit line secured by your house. During the draw period, you can borrow money as invoices become due, up to the approved limit. You pay interest on the amount drawn—not necessarily the full limit.

Main risk: many HELOC rates are variable. The payment can rise. Some offer interest-only payments during the draw period, followed by a larger payment during repayment.

What is a construction loan?

A construction loan is designed to fund work in stages. The lender normally releases money in draws after reviewing progress. It may require plans, permits, a signed construction contract, budget, contingency, contractor information and inspections. Some loans convert into a permanent mortgage; others must be paid off or refinanced when construction ends.

Renovation loan

A renovation mortgage can combine a home mortgage with approved improvement funds. Programs such as Fannie Mae HomeStyle Renovation, Freddie Mac CHOICERenovation and FHA 203(k) are offered through participating lenders—not directly by those agencies.

Cash-out refinance

A cash-out refinance replaces the existing mortgage with a larger new mortgage and gives the owner cash. Compare the new rate on the entire mortgage balance. Giving up an older low rate can make this option expensive even when the project portion looks attractive.

What interest percentage will you pay?

There is no honest single number. Rates change with the market and with credit, income, equity, term, loan size, property and fees. Get written offers on the same day and compare APR, points, fees, monthly payment, fixed vs. variable rate and total interest.

Easy stress test: if considering a variable HELOC, calculate the payment at the quoted rate and two percentage points higher.

What to prepare for a lender

  • Estimated property value and current mortgage balance.
  • Income, monthly debts, credit and cash reserves.
  • Project scope, early plans and realistic budget.
  • Design, permit and construction schedule.
  • Construction contingency—not only the contract price.
