Defect #2: Worn Roof…most likely it will need to be replaced. If the seller will not do so, negotiate a lower price.
Defect #3: Termite/Carpenter Ant Infestation…the house could be in need of expensive structural repairs. Unless the seller is willing to help pay, it's probably not a good investment.
Defect #4: Outdated Wiring…this can be expensive to correct, and is a dangerous problem. Negotiate with the seller after getting an estimate from an electrician.
Defect #5: Damaged Shower Pan…get an estimate from a contractor if you find water under the shower, and negotiate with the seller to cover costs.
