Maybe need some deep piers and consider seeping water/radon/methane/natural gas or whatever else was mined there. 

Hi BP,I'm writing this post because I'm neck deep in analysis paralysis and trying to claw my way out.

Its a deep passion of mine and I'm thankful that it was recommended to me by the GAREIA.  

The principal broker had jumped in and dug deep into the situation.

But this being my first experience of a rental property owner, I took a breath, and figured out how this could work.

Take a breath and vent here, not at the tenant. 

Very helpful and I will be deep in study as you read my reply!

If as I suspect you have not included all expenses the property is likely deep into negative cash flow and you would be miles ahead to sell and take advantage of the opportunity value of cash.If you could pull out the equity and still cash flow (unlikely) it may be worth keeping otherwise it is a loser.

Well sealing,  just to let you know depending on how deep is how much.. recent bid was 2000 to seal and 800 to remove the large holding tank..I using one of the companies listed above for the work. 

Here you leverage experts that already know what markets to be in, where the best deals are, structure the best deals and have an experienced team....ride it to profits if you don't have time or the inclination to learn at a deep level.
