Not sure if you are still interested in a 4 bed/3200sqft/3 car garage home in Farmington, but, 15480' rented on 9/1/12 for $4000 per month and I got a couple into a 3519' rental for $3000 per month on 7/1/12. For 2013 three properties rented and the highest was 2412' for $3000 per month in February. I hope this gives you an idea.
However, rates seem to be inching their way up to 4%. The usual indicators are not working. Meaning, when equities go up the 10 yr goes down and rates go up. There have been inconsistencies here as of late. It takes 6 months for a fed change or rally (or whatever makes the market react) to resonate through the economy. I have a feeling the rates will be climbing by June. I hope I am wrong! I, too, own a home and would like to refinance again should the rates go into the 2% range. That said, it is a great time to buy if you are in a position to and if you are not here on short-term basis.
