Looking at buying an older home with abestos siding. Currently it is in good shape, desperately needs a paint job. Questions that I have are: a) What type of sealent needs to put on the siding before it is painted? b)What, as a the owner, will I be responsible for when I sell the house? How difficult will it be to sell with the abestos siding? c) What do I need to do with lead paint inside the house? d) selling factor there too?
