Utilities - does it need city sewer and water, or can well and septic suffice?

We learned early on that:-3 of the 6 buildings are in a flood zone-the current owner has a loan, this lender doesn't require flood insurance-1 building took on a little water at one point during the 12 years the seller has owned the complex. 

And if there is a conflict the court system will bend over backwards for a dead beat tenant or squatter and hold landlords to a entirely different standard. 

he has been running the hot water intentionally to run up my water bill so my tenant dont have hot water to shower. my water bill is now $800 a month.

It’s durable, water-resistant, and easy to clean.Countertops: Laminate or quartz countertops can be more cost-effective than granite but still offer a modern look.Paint: Choose neutral colors to appeal to a broader range of tenants.3.

I once spent all night pumping 3 feet of water out of a basement, in a monsoon, using a DC pump attached to my truck battery because there was no electricity to the house and the sump pump couldn't work.

The stove & hot water heater are currently electric. 

I'm finally looking to get out of analysis paralysis and pull the trigger on my REI journey and i want to start out as a co-host on AirBNB to learn the ropes from someone more experienced, learn enough to where I feel comfortable to host my own and earn a few dollars in the process.The only issue I have is that I have no experience as a co-host and per AirBNB's standard, i currently do not qualify as a Co-Host.

Given my income and credit score it's more than likely I will qualify for any loan program with high standards.

But if all your imagination is able to see happening in the next thirty years of real estate investing is that you will pay off your mortgages slowly and steadily, you're already dead in the water.
