Burlington, Vermont is home to one of the best real estate investment markets in the country. In Burlington, you can purchase a multi-family investment home for significantly less than you can in other U.S. cities, and the rents are just as competitive. A duplex in downtown Denver, for example, might sell for just under $800,000, but the average monthly rent is $1,634. In downtown Burlington, however, it is possible to buy a duplex for under $400,000 and the city’s average monthly rent is $1,770. Needless to say, Burlington real estate is an excellent place to invest if you want to see large returns.
