Buyers do not deduct repair cost, they deduct repair cost plus hassle plus a margin for whatever else might be lurking.

Get quotes on the two or three biggest items even if you never intend to do the work. A written number from a contractor for the furnace or the shingles replaces a buyer's imagined figure with a real one, and imagined figures are always worse.
