Some insurance companies are asking to see the home inspection report in order to give you insurance or to install a $750 water shutoff valve if the home is older than 20 years old.  

In regards to having a EV charger, Id seen a lot of people install the outdoor rated ones in their STR and it helps to draw the people that may be renting a EV during their trip. 

- How can I estimate expenses for installing utilities and creating roads, sidewalks, and drainage systems?

Lol.....Maybe I should develop a business model that installs them...for a slight additional fee. 

Are you installing new smoke alarms?

RJ Gullo advertises everywhere about 1031 exchanges - I've never used him, but I know he does them.From what I understand about what you said it looks like you are trying to do an installment sale (downpayment now, then payments overtime).

Or should I have Ring cameras installed outside.

By installing our own, we remove the wear and tear and damage the tenants do by moving W/Ds in and out and hooking them up wrong (which is common) and using cheap components that cause leaks and destroy floors and walls.

You can use a card reader on the coin-op feature to address that, but you are into micro-issues at that point that I wouldn't want to deal with.A proposal: Tenants, installing separately metered water and electric lines that I pay for, then bill you for, will cost me $5,000 (or whatever).
