I bought mine at a Very Unique time, Closing on Oct 28 2008. It was after the housing prices initially fell and during the time Banks were closing left and right. Lenders would give loans like candy but only to those with Excellent Credit and would still do the crazy ARM loans but not even look at you if you had middle of the road or worse credit. I bought the townhome for 150K. During the bubble the same place would have sold for 200K+. My loan was FHA, no ARM BS, but had a high interest rate of 6.75%, and only 3K down (basically 0% down). I was only making 38K a year at the time. The day of the closing the Sellers Bank announced it was being bought out which lead to the Lawyers freaking out and doing everything via paper with triplicate copies of everything. It was not easy as I spent a couple years struggling to keep up with payments as I took a pay cut at my job and did work a night job to make ends meet but I always paid my bills on time.
A couple years later my place appraised for 89K with foreclosures dragging the prices to the floor which put me way underwater on the loan. I had excellent credit still and refinanced, I think through one of those government funded programs, with a low interest rate saving me $400 a month. Since then the prices rebounded nicely with several units in the neighborhood selling for 130K-140K so I'm no longer underwater on the loan and have a great interest rate. It was not easy but worked out well and have gotten a couple promotions at work too so I'm getting paid considerably more than I was in 2008 and have been looking at getting a single family house and renting the townhouse to family.
I've been told in todays market I would have never gotten that loan like I did in 2008 so I was lucky as Fuck to get the place.
