The only thing that sounds out of the ordinary here is the water bill

Metron and Southern Water Management are two that we've been talking to.

Can fix the water damage in the basement yourself.

.: Quote from @James Jefferson: Hi, I have a family member that had a reverse mortgage on their property it's a 3b 1b 1 acre of land heats by oil no hvac and on well water.

It's hard to say offer amount without knowing the rehab part since that could blow this out the water.  

@Marc Robinson what's the lot rent, who pays what utilities and what's the source of the water and sewer?

Given they are going to damage the walls while moving anyway it eliminates their need to touch up the halls and I can usually schedule to have one painter knock out multiple units in a day but even if its a one off sale, it comes across as good service for a small amount of money.In a storage area within the house or garage I will leave an unopened box of each tile, and flooring used in the house along with unopened 1 gallon buckets of the wall and semi gloss paints and one of each door hardware (kitchen and interior doorway.

I'm new to the real estate investment game and I'm a bit nervous about dipping my toes into unknown waters. 

You said public water was available...would the lots require a septic system to be installed or is public sewer available? 

When i replace water heaters i replace all the short pipes.
