In this market, buying a home isn't always the best financial move to make. By Cameron Huddleston, Former Online Editor July 29, 2010 Some traditional rules of personal finance need to be tweaked to mesh with these tough times, according to the September issue of Kiplinger's Personal Finance, which hits newsstands August 10. Among Kiplinger's 12 new rules for your money, we suggest that renting may beat buying a home. Buying wins when home prices are rising -- and that's not the case in many places.

See Should You Buy or Rent? for tips on figuring out whether your market still is in the bubble zone. 3. See cities where home prices have held up best and cities where home prices have fallen most to get an idea of whether buying a home where you are makes sense.
