Furthermore, some installations, such as his antennas on a pole, are on my land.I am a reasonable person and don’t have any issues with this.

@Joshua Melero We had vacant property that were remodeling and considered installing cameras inside the property.

I asked her to get it installed.  

I’m waiting on a contractor to come install an egress anyways, so the extra month it’s taking me to do minor repairs and paint  hasnt affected the schedule yet, but it’s definitely an important lesson.

I would have required that a professional install it.

After moving out, we re-stained the front porch posts with a darker stain (photo is pre-stain), replaced the front door, did touch-up painting on walls and trim, installed new keyed-alike locks on front/back door, and installed a vented bathroom exhaust fan that wasn't there prior. 

I had them installed during the remodel up there.The first floor where my wife and I currently occupy is also recently updated with a new kitchen, all new appliances and is also a 2 bedroom with a fully finished basement.

Keep in mind, you will likely have to install a sprinkler system, among making other changes for the home to be used for that purpose.

I know someone who installs security systems.

After a thorough review of systems, we had plumbers troubleshoot and repair/replace a couple of small chronic bathroom leak issues, and electricians installed a number of end-runs back to the panels so that rooms could each have window A/Cs running without tripping circuits and other such issue.
