My rental condo in Asheville, NC was spared damage from the flood, but when the city finally turned the water back on a few days ago, they somehow overpressurized and blew out a fitting inside a wall. 

Primarily desert washes, but also near a creek....So I would go knock on doors and ask neighbors when it has flooded and what they think about the area......maybe call the County water board and ask then what has happened there in the past.

There's no way I can keep the house above water with that rent let alone consider any positive cash flow...so I need them out!

It covers internet, water, trash, cable, and exterior (roof, siding, etc.).

water heater? 

OP, keep in mind not having access to heating and sharing same water heater and etc will require an easygoing tenant in the nextgen.

Like deferred maintenance, (bad roof, worn out water heater/AC Unit, warped flooring, water damage) etc, unpaid utilities,  unpaid taxes, a second loan, unpaid HOA fees, a bad pool, bad reputation, sometimes squatters, sometimes they were drug houses, and so on.

The licensed plumbers do not get permits for water heaters, I have never heard of one being red tagged solely for not having a permit so I do not get permits (and know no one that does) for swapping a water heater.  

Purchase price: $275,000 Cash invested: $45,000 Sale price: $400,000 Contributors: Adam Schooley This townhouse, which had gone through probate, suffered from significant water damage to the drywall and required updates throughout.

For example, I have a subject property that has 1682 SF on the main floor and 810 SF of finished basement (the majority of which is about 8 feet in height with the exception of some bulkheads to hide the mechanicals) and 271 of semi-finished basement that is a utility room basically (washer/dryer, freezer, hot water heater, furnace, some storage).
