Thanks for the suggestions. Before I moved in I had the entire interior of the house (including ceilings) painted. Even did a walk-through to sign off on the work. There were no holes after all the painting. So they were created after.
Looking into some of your advice. Been up there myself - I think whoever it is filming/watching me with their camera phone. My dogs even react when they hear the foot steps and they look up to the ceiling! Trying everything within reason to get to solve situation.
After I moved in I noticed a couple different male neighbors had been overly friendly or try to time things to bump into me while walking dogs. I wonder if something posted online and they are in a Facebook /Nextdoor group or group text sharing images of me!
Soon to be ex husband not happy about having to split assets. Don't know if him or some crazy. I haven't dated in 30 years nor do I want to -- so don't know exactly who it could be.
