I'm not sure exactly how homes are appraised, but from what I can tell the values have continued to rise in my neighborhood. Price per square foot is about 10-15$ more for recent sales than what I paid for my home and I have the addition of a 2 car garage where most of the homes have no garage (older neighborhood) so I would think that would be worth something, maybe not though.
The 30 year fixed at penfed is 6.125%. I'm pretty risk tolerant, but I don't necessarily see the 5/5 ARM as that much of a risk... worst case is that the loan adjusts up 2% (max) after 5 years and stays there for another 5. Using simple math, this would give a 10 year interest rate of (5.125 + 7.125) / 2 or 6.125... so after 10 years, there is no real risk. If it went up another 2% after that we would have (5.125 + 7.125 + 9.125) / 3 = 7.125 for 15 years. This doesn't really seem highly risky to me... and this is simple math assuming the worst case. I would expect the actual effective rate to be lower than the simplified version because the loan value will be less as time goes on, and more principal will be paid down during the first 5 years with the lower rate. I may be missing something though
I'm really looking for 4.75 or so to push me over the edge. If it gets much closer to that my trigger finger will be very itchy.
