If it is not on paper it is as good as vapor. 

We were given a 60 day notice but just heard from the owner yesterday about her being willing to sell it to us.

What ended up being the problem was that ground water was getting vaporized by an electrical charge from the the power supply underground servicing the pool. 

It would be my fiance and I living there and I want something that I would feel comfortable with her being alone at.

My question is, if she is in school and their for not paying on her loan how would the lender or underwriter calculate that into my monthly income expenses or would we have to already be paying on the loan regardless of her being in school at this moment.

I'm glad you aren't posting about her being 6 months behind and asking for advice at that point.  

Not knowing the type of "factory" that you are operating, you may also need to keep in mind that vapor intrusion *could* be an issue for an adjacent multi-family residential building.

To give you a bit of background, my girlfriend is a broker as she was able to apply for her license due to her being a lawyer.

This batt insulation should not have any kraft paper or vinyl facing (vapor retarder) on it as this will create a condensation and mold problem. 

I spoke with him yesterday and have him the option to break from lease AS long as I get someone lined up to move in before he leaves,  as I feel he probably won't be the best tenant to keep in the long run especially with him and her being just above the minimum 3x income vs rent.
