You probably wouldn't need a "general" contractor, who (like me), would subcontract plumbing/electrical/HVAC work, though some towns permit HVAC work to be put on a general "building" permit.I'm not entirely sure what plumbing and HVAC work the previous contractor did but you may (sometimes) have issues with plumbers and HVAC guys taking over or signing off on work done by previous contractors that they can't or don't want to put their name behind (or they may charge you more simply for doing this)... depends on the company/person, and on the nature of the work done.

I am OK with water wells but agree that rural areas and lagoons are deal breakers.I would add “lack of sufficient affordability gap” to the list of deal breakers.  

I want to note that I am not interested in taking business away from any investors; simply a connection with a good contractor that experienced investors use but maybe do not have the capital for a deal at this time.

Aside from the lack of ups and downs, there is a lot of opportunity in rental properties.

Most of the stuff I’ve been picking up lately is more on the motivational side which I really don’t lack lol.

Find a private lender that will simply act like a bank with interest rate from 7-12% and keep the rest for you.

Whenever a wholesaler contact me I simply get the information about the property & reach out to the owner myself cutting the wholesaler out of the deal entirely.

Of course, sometimes we simply cannot find actual rents.

It's possible the tenant is better at this sort of work than both of us but you never really know...If I were in your shoes, I'd have a licensed contractor do plumbing and electrical but that will cost you more.I guess it comes down to whether or not you want to pay more or take a chance the tenant is doing it correctly, in which case you can simply be happy that the tenant is happy and also that he's saving you $, at least in the short run.

More than likely this could be fixed by simply buffing the floors and applying another coating.
