I am hearing from some loan agents that mortgage rates fell slightly this last week. Freddie Mac monthly averages showed a jump in rates in June 2013 to 4.07% followed by a slow rise for the following months including a very slight rise in September to an average rate of 4.49% with 7 pts on a 30 year fixed mortgage as of Sept 27, 2013.

Trulia has estimated that a mortgage rate of 5.2% in the San Jose region would tip the cost of buying to be higher than the cost of renting. Yes, they believe that if you own a home for 7 years (with some other assumptions), it is currently cheaper to own it than to rent it.
