The land owned by somebody else was not sold at tax sale only the former improvement.I saw a property sold at tax sale that was at the bottom of a man made lake.I saw a property sold multiple times at tax sale that was a bombing range for the Army.I saw a country house sell at tax sale that was a gas station site in the 1930s and still had leaking under ground tanks on the property, and there was an existing lawsuit by a neighbor claiming health damage and birth defects from gasoline tainted wells.I saw a property sell at tax sale that was five acres with road frontage except the road frontage was a fifty foot cliff.I saw a property sell at tax sale that was 2 ft wide, residual from a highway expansion project that took the rest of the property.Properties have sold at tax sale that were no existent due to mapping error, title errors, surveying errors, or some other issue. 

Gas was off for a few weeks, and now that it's back on the water heater isn't working.

A lot of folks use a conventional brokerage IRA to accumulate some savings and then switch to a SDIRA once they have some gas in the tank, so to speak.

I have paid water,gas and electric. 

besides the general walk through of each unit, I'm thinking i'll need to bring on specialists to check out big items including roof, ACs, water heater (one centralized gas unit for whole complex).

For example, oil and gas is even better. https://www.investopedia.com/articles/07/oil-tax-b...Another area is agriculture.I've heard that Steve Newlin is a good accountant in Chattanooga, but I haven't met or worked with him personally.

I worked as a property manager for a time (regular rentals - not VRBO style) and we had a client, Baker-Hughes, the worldwide oil & gas company.

How about water, electric, gas etc.? 

If you're cleaning the gas stove and you bump one of the knobs, odds are good you're going to smell gas.
