What is Blend-and-Extend?
A blend-and-extend mortgage is a refinancing option where a borrower combines their current mortgage rate with a new, typically lower, rate and extends the mortgage term. The new blended rate is a weighted average of the old and new rates.
Why Blend-and-Extend Matters in Real Estate
Blend-and-extend matters in real estate because it allows borrowers to take advantage of lower interest rates without breaking their existing mortgage contract, which would otherwise trigger penalties. It can help reduce payments and extend loan stability.
Example of Blend-and-Extend in Action
A homeowner with a mortgage at 6% blends it with a new 4% rate offered by the lender. The resulting blended rate is 5%, and the mortgage term is extended, lowering monthly payments without penalty.
