When you gain experience as an investor, you'll begin recognizing issues when you do your own walkthrough and an inspector or contractor can confirm it for you.If you want to proceed with an offer on a potential property, you should include an inspection contingency in the offer to give you the opportunity to back out of the deal should you find something in the inspection report you are unwilling to deal with or if the seller is unwilling to address through a satisfactory concession or repair.Good luck!
