The interest rate that was quoted to you on an ARM vs fixed would have a lot to do with your decision making. If you truly know that it is a 7-10 year stay that you plan and if the interest rate is lower than I would recommend the ARM. Making sure there are no penalties on paying off early and that the closing cost up front are in line with other mortgage programs available.
Curtis Jann,Were you able to get assistance in viewing this home?
Just a little info on the answers provided below. A CMA usually ranges from $100-$150. Some realtors will do a CMA for free in hopes to be able to list your home at some point. While others knowing you just want information and have no intentions of listing through them will charge a fee because a CMA does take time to put together. I hope this helps.
