IAFarmer after rereading your post I see you have boys,if you remodel this old house there will be lots of dust and most likley lead paint dust this is very dangerous for your boys,lead effects kid's and pets more than adults. At the very least have a lead inspector check were the lead is. Many state now make you remove all lead paint before you sell and many more are headed in that direction, once they pass that law you have to hire a lead abatement contractor to remove, and if that sounds like lots of money you are correct. I hope this helps you with your problem. 42 yrs swinging a hammer. And I still say RUN. JMD
