If you live in NYC I might suggest looking into Property Shark.

I'm told North Memphis is unwise to be there without a battle tank.

I always say a bigger shark will eat up a smaller shark a store may no longer sell a product when it goes out of business but if the demand remains another store will step up and sell that product

Worst case scenario still doesn't look terrible if everything else is as it sounds (rehabbed, new tank, long term tenants, up and coming neighborhood, price/rent ratio, etc etc). 

This seller would be MUCH better off not dealing with this shark.

Also ask your oil provider to see if they offer a filter change before they fill the tank for additional cost?

This is his action plan:Locate septic tank remove concrete slab between building locate belly in the drain line.

So it’s not too old and 5500 sq ft building with gas pumps(4 MPD, which is 8 Pumps) & underground storage tanks, which are three tanks.

It's a 3/2 and I essentially went over anything and everything that could break - new light fixtures, new plumbing fixtures, p-traps, updated electrical to include GFCIs, new sewer line, cleaning of furnaces/hotwater tanks, new key code door knob, fixed the gutters, paint, flooring, switches, etc.

Looks like you have enough cash you don't even need to...I just wish I had years ago as the market tanked right after we bought our first house.
