How will the conflict with Iran affect the housing market?

Honestly, no one really knows. Global conflicts can create some short-term uncertainty, mostly through things like oil prices, inflation, and mortgage rates, but the housing market is usually driven much more by local supply, demand, and interest rates. Historically, events like this tend to cause temporary market reactions rather than major long-term changes in real estate. If you were already planning to sell and buy, it usually makes more sense to base that decision on your personal situation and the local market rather than trying to time global events. The best time to buy or sell will ALWAYS be when you are ready to buy or sell.
