I can get a system installed for $4500.

There is a significant expense in siting, engineering, and installation that most companies do not want to incur jumping from one pole to another.There has been a trend in the industry to buy out the landowners with a perpetual easement.

Both need some minor rehab (new carpet, install appliances), but nothing crazy.As an out of state investor, how can I get contractors inside and screen for tenants and give them the keys while out of state? 

Also, only licensed electrician can request them and inspections done after installation.

After hurricane Michael, we rebuilt our fence, carport, added a drain field line, and installed a new front door.

Now the landlord says i need to cover the cost since i installed it.

@Susan Ali I would start with installing ceiling exhaust fans they wire in fairly simple. 2nd I would remove the water damaged area and see if there is any moisture damage above it indicating a leak from up stairs.

The units have badly installed cheap damaged linoleum floors.

We installed a new kitchen (fixtures, appliances, some plumbing upgrades), new baths (wall/floor tile, vanity, fixtures) and paint/minor carpentry.

Can I add a addendum to a lease to include the electric payment to me rather than Edison on a newly installed solar system?
