Jay P123, don't let him get you paranoid at all, outside of people in your own area recognizing the houses you have little to worry about.
His photo's contain no exif data of any sort, which means no geo location data (this makes it difficult to locate), no time of shot (lacking gps this makes it near impossible to locate), not even the make of camera that took the photo. There are folks out there who could if they know time of day photo was taken, deduce roughly what region the photo was taken using shadows and trig, likely down to what neighborhood he resides in, those people have better things to do than rip off some cannabis because those people tend to have degrees and careers though.
If you believe me mistaken then I urge you to prove me wrong, pm him where he lives and the calculation showing how you arrived at that address (I say pm because it is no one else's business where he is).
