Here is another interesting map of the United States, this one presented by Trulia real estate search. This time the map indicates which major cities are cheaper to rent in and which major cities are cheaper to buy in. Topping the list of cities that are cheaper to rent in should come as no surprise: New York City is notoriously expensive to buy a home in. On the other hand, major centers such as Phoenix and Miami are far better for buying a home (perhaps because housing prices fell so drastically in these cities?). The numbers are bit more confusing than the colours and are the result of some complex calculation to determine what is cheaper. But the main point is that the lower the number, the more it makes sense to buy within the city.
