Here are are few
water stains on the basement floor?
calcium or other mineral deposits on the basement floor or foundation walls?
Anything that appears to be mold on the framing of the house?
Any foundation wall cracks, settling, movement? – Industry standard is up to 1/8″ of seperation. If there is that much, I would be asking a heck of a lot more questions.
Was a proper sill seal foam used or insultaion beneath the sill board to the foundation. If insulation – I would stay away from it. Insulation wicks water from the foundation and will rot the .40 treated sill board
How is the rim insulated? Closed cell? Batt? Min R-21 and iar sealed. – Do you see spider webs flapping in the wind?
Electrical service – fused or breaker? What size service? Will it fit your needs?
Age of water heater, water softener, furnace, well pump…….All have a life expectancy typically of about 10-12 years. How soon to you need to replace?
Exterior –
Roof, condition and age. Avg is 30 years. If its 25 years old, well you’ll be putting out $$$$$
Caulk, flashing, trims, siding, window trims…. If its been neglected for a few years, chances are other things in the home have been neglected. Does the water go out and over on EVERYTHING??? Look for rotten trim edges. If you have rotten spots in the trim, most likely there are other issues.
Condition of windows and sashes? vinyl windows are ok for very short term. The frames warp and move and they all eventually leak air. Wood sach windows =- be ready to fork out some money to replace.
Alluminum clad windows – find the manufacture and approximate year of manufacturing (stamped on tin between glass) and do a search on them. If they had a crappy year or two, you’ll see a lot of blogs blasting them.
Inside – look for any patch jobs in the drywall, stains, discoloration, cracks, bubbles,…..If there are any, there is a story behind it.
If the kitchen has an island, place a clear glass of water filled 1/2 way on it. Walk past it in a couple different directions. If you see water rocking back and forth, you know the builder used the the lowest rated floor joists. If your thinking about adding granite or other stone tops in there…you may over-load the floor in that spot. Fix is web stiffeners.
Are all the bath fans ducted to the exterior? Hard pipe or the cheap accordion springy crap with no insulation.
Remove a few electrical covers and switch plates on the exterior walls. Do you see signs of air leaks? Same for ceiling fixtures.
Attic – how well is it insulated? Energy heels on the trusses or rafter framing with insulation (non-compressed) out over the wall top plate? Spot check a few electrical wire holes in the attic. Were they fire stopped? If not, you have more air leakes from the basement to the attic.
Well, this is about 1/100th of what I look at when I punch list a house
Good luck
