I agree with everything here but also want to emphasize talking to other residents on the block, and observing the block at different times of the day (if you can). Our block is great and we have a nicely knit community- except for the house directly next to mine. Had I spent time checking out the neighborhood I might have seen the residents nodding out on their porch, dumping huge amounts of trash out of their cars into the street, having stoop parties and doing drugs openly. These neighbors had a busted pipe in their home that flooded my basement for a week until the city finally intervened. I get roaches, from these neighbors. They are the bane of my existence.

Also, make sure to check around the transome. Ours wasn’t sealed correctly and now the entire door frame needs to be replaced because of water damage.

Good luck!!
