Interest rates will probably go up at some point in the next 12 months. I don’t expect them to skyrocket all of a sudden; the most likely scenario seems more like they will creep up by 0.1% at a time.
The downside on a 104k house is probably pretty low right now. That and a 5% further loss on a 104k house is barely over $5,000.
If you really like the home and can see yourself there for 7+ years, why not buy at this price?
