It would be like opening a restaurant that limited it's clientel to one generation.You seem deadset on it though and don't really want or need our validation/approval...best of luck to you....

However, for me, I would do NOTHING except issue them a lease violation warning and use their uncorrected lease violation as another valid reason to evict them.

I am contacting you to formally request validation of the alleged debt concerning this account and to inform you that I hereby dispute the validity of this debt.

Your lease was with the tenant, not that LLC and anything that LLC sends you might not be valid. 2: Your lease was with the Tenant.

I found the county criteria which reads as:"Property must be minimum of 1 acre, meet the underlying zone district, have adequate parking, meet the requirements set for by the Wildfire Hazard Overlay District, have valid water and sanitation, have legal access, use the primary dwelling unit, be free of violations, and have no substantial detriment to the intent of the Zoning Resolution."

Their inspection contingency is still valid a week from closing?

That may be valid in situations that you have been in, but that mindset doesn't apply to every deal so the blanket opinion to just "cut losses" and "move on" is useless.Wrong. 

The tax transcript is a little abnormal, but I would assume it is to validate a lien or judgement on the background report is paid off.

You can say firt 30 days, warranty and later its on them may be.

It is your responsibility to have a legal, valid lease and understand exactly what it is in it.
