@Dan GrossmanSecurity cameras and Jersey barriers to block vehicles.

Make sure you get a sewer camera run.

I leave my doors unlocked with a security camera inside. 

It's still important for trash if you have a big dumpster to have locked access, lighting, and possibly a camera to help prevent illegal dumping and running up your trash bill.The water department if you have a leak the process typically is to get a plumber or similar to find the leak and repair it.

I had to repair the driveway, new fence, do the roof suffice, new kitchen cabinets for one of the units, fix the front and rear decks/porches, installed security cameras, eviction cost of 3k, dumpster cost, paints, interior door

The places i've seen has the plumbing/electrical/HVAC so its a fair simple go.I will admit I spend $2000 on cameras, and exterior lighting.  

I have the equipment to test the pan with, moisture meters, FLIR camera etc.

I tell them to plug in the security camera, leave the keys on the table, and leave the front door unlocked (because they will forget something and be locked out of the house).  

I also had the idea of placing a home security camera in front of the thermostat and simply view it on an app from time to time.  

Also "before" pictures were taken with iPhone camera which can't be compared to a 5K-6K professional camera.
