As a buyer it is super important that you pay attention to red flags when you’re touring homes. Some of these things could be: a lot of homes for sale on the street; really busy streets; railroad tracks in front of the house or nearby; damp and musty smells in the home; strong odors or air fresheners; water stains on the ceiling of cracked foundation walls or stains on the foundation walls as well. As well as missing downspouts or downspout extensions or any standing water in the yard or sloping back into the foundation. Any of these things that you find may be red flags, and they might also not be a problem. So just pay attention to them and look into them.
