Every year Realtor.com releases its list of Hottest Zip Codes For Prospective Homebuyers. For the second year in a row, a quaint Texas suburb took the top spot. Realtor.com's Chief Economist Danielle Hale reveals the winner and the rest of the top 10. She also explains what factors go into making the list. Many of the zip codes on the list are suburbs to major cities. We know that cities across the country have seen a population boon, but it turns out the suburbs outside of those cities have, too. Since these zip codes are seeing an increase in demand, median home prices are higher than the national average. However, they are relatively less expensive than many surrounding zip codes in their respective areas.
