This will get you out of paying PMI, and of course the interest on both loans is tax deductible - PMI is NOT tax deductible.
Actually, yes it is. New tax laws which went into effect stated that on your 2007 taxes, if you closed on a mortgage during the calendar year you can claim ALL of your PMI if you make less than $150,000 (I believe) as a single person. This tax "break" has been in effect for a few years actually and I believe was recently renewed for the 2008 calendar year. So what it means is that your PMI will be a nice tax deduction.

One other thing regarding buying a house that you should be prepared for are the unexpected "surprises". When I had my house inspected, the inspector let the water run out back for hours on end and there was no water problem in the basement. We had TORRENTIAL rains in our area during October and November, and yet the basement drainage system worked perfectly and everything was nice and dry. Recently, we've had some really cold days and the ground froze solid. On Wednesday, we had a massive snow and ice storm hit the area followed by a few inches of rain on the same day. The ground, however, was still frozen underneath and all around my neighborhood there were HUGE lakes forming in the low lying areas as the water wasn't draining.
Well, the water has drained and it drained right into the middle of my basement. It's seeping up through the concrete and into the low lying part of the basement. Wherever there is a crack or chip in the floor, water is seeping up and there is about 1/2 to 1 inch of water in the center. The drainage system is still working and the amount of water being pumped out is remarkable, but the insane amount of water in the ground is just overpowering it. I just need to pray that the moisture problem will be covered in the Lifetime Guarantee of a completely dry basement that this drainage system has, and that the water won't rust the boiler which is right where the puddle is.
The ONLY way this could have been detected during an inspection would be if they took a few thousand gallons of water and poured it all around the foundation. I guess the water table has just risen slightly above the floor level of my basement and it's now forming puddles.
