Interest Rate and House Prices

The Interplay Between Interest Rates and Residential Housing Prices

This document explores the fundamental economic relationship between interest rates and the valuation of residential properties. Understanding this dynamic is crucial for market analysts, policymakers, and potential homeowners.

The price of housing is highly sensitive to the prevailing interest rate environment. In the residential market, the primary mechanism for this sensitivity is the cost of securing a mortgage.

Mortgage rates are directly tied to the Federal Reserve's monetary policy and the overall credit market. When central banks raise the federal funds rate, borrowing costs across the economy, including mortgage rates, typically increase.

When interest rates rise, the following effects occur:

1. Increased Monthly Payments: A higher interest rate on a fixed loan amount leads to a larger monthly payment.
2. Reduced Purchasing Power: For a buyer aiming for a fixed monthly budget, a higher rate means they qualify for a smaller loan amount, effectively reducing their maximum affordable house price.

The table below illustrates how changes in interest rates impact a fixed monthly mortgage payment.

Interest rates serve as a gatekeeper for housing demand. Lower rates broaden the pool of potential buyers by making mortgages more affordable, which pushes demand up and contributes to price inflation. Conversely, higher rates shrink the pool of qualified buyers, reducing demand and placing downward pressure on prices.

While the impact on demand is the most immediate and visible, interest rates also affect the supply of housing in several ways.

Higher interest rates increase the cost of financing for construction loans. This can lead to:

• Slower development timelines or cancellation of planned projects.
• Increased final costs for new homes, which builders must pass on to consumers.

High interest rates can lead to a "lock-in effect" for existing homeowners with low-rate mortgages. They may be reluctant to sell their current home to purchase a new one at a significantly higher rate, which limits the inventory of available properties and can partially offset the downward pressure on prices from reduced demand.

In the short to medium term, an inverse relationship generally exists between interest rates and house prices, assuming all other economic factors remain constant.
