Better to Rent or Buy? Check Out Trulia's City-by-City Index

Before you shell out that big down payment on a new home, see if you're better off renting. Trulia.com, a popular website that covers the housing market, has calculated the affordability of renting vs. buying in America's 50 largest cities. Miami and Las Vegas top the list as ideal places to buy instead of paying a landlord. New York City, with its median unit price of $1.3 million to $1.4 million, occupies the bottom of the index, meaning that it can make more sense to rent.
