How big of a mortgage can I realistically afford?
I bought a house 6 months ago for $240,000 on an $80k salary am getting by just fine and am able to save money (and I live on Long Island, an extremely expensive area to live). I would look at finding a few more interest rate quotes; for instance, Wells Fargo is offering 4.25% right now for FHA (first time home buyers) loan (which only require 3.5% down). A lower interest rate will lower your monthly payment. Make the banks compete with one another - this little bit of leg-work will save you thousands upon thousands of dollars in the long run). Also, try to negotiate to NOT paying a point down on the mortgage - most of the time they are bull, especially in this economy (banks are desperate for new loans).  However, as others have said, do not assume or count on rent coming in to be able to afford your mortgage (unless you are married). What if your friend moves out and you cannot find another tenant?  However, I strongly recommend you talk to a financial adviser and your bank mortgage loan officer to work out the numbers - you will be surprised what you can afford when you factor in your income tax and mortgage interest write-offs.
