You could also try doing a brute force method.I paid a virtual assistant on UpWork (Odesk), $9 to generate a list of contact info for all contractors within a radius of the subject property.This gave me a list of 200 or so contractors.  

I would then have her sign a copy for her and one for me ensuring that she and her parents know that I want to do my best not to evict her, but that the lease is a legally binding contract and that I am forced to follow it.As has been mentioned, this is a people business.

@Deb Merrill I would probably go with natural gas forced hot air.

It seems to be a way to force us to accept pets that we may not want to.Anyway, here is an idea, given that the tenant is a good one.

Many universities (like the UC system’s “concurent enrollment” in California) will let you take classes for credit without even applying for admission.I personally do not think that just reading a book is the same value as taking a university course because when you take a class you will be forced to really study the material, grapple with it, work with it on exams and projects, etc.Economics 101 - macro or micro.

With all the layoff in Oil and Gas right now i was forced to pay more attention to my job while still have to keep an eye on all the current rentals, while expanding the portfolio. 

I'm not a lawyer, nor do I play one on TV, but I've heard of others in similar situations having to go to court to get a partition decision to force the sale of the property.  

I need to force myself to look at the big picture.  

What are the chances they will begin to force connection to the sewer ... perhaps when homes change hands?

Ultimately, if the tenants aren't going to cooperate, then there's not a lot you (as the wholesaler) can do to force them to (even if it's in the lease), and it doesn't sound like the current elderly owner is in a position to get involved.
