If there is "still contamination" at any level, I would be concerned about that and pass on the deal no matter what.

We have a balance of 266K on the mortgage @ 3 percent interest.

For example:If a wrote up a contract between myself and the LLC for a loan on said money and the LLC was sued and forced to sell the property.

I’ve heard different things like taking a Fannie Mae loan out then converting it to a LLC and the likelihood of triggering a due on sale clause is minimal.

What is there now is a hardwired system on each side but we need one that talks across the property. 

Selling property for top dollar is not as simple as putting it online.

Online options: Many counties have online access to property records through their official websites.

I’m not 100% sure if this is what you are asking, but if you put 10% down at purchase you probably still have about $360k on your mortgage.

That is not a benefit for you, nor any kind of evidence that they are worthy of becoming a resident.That issue aside, I would not allow someone with a recent eviction on my property unless the "unfortunate circumstance" was unlikely to recur AND they otherwise have a strong historical track record of making payments AND they would put down a very large security deposit.

I am considering using them for EMD & LLC on an upcoming purchase.
