I am following this thread but didn't receive email notifications. not sure what happened.the servicer is saying that they won't allow the homeowner to cure the default, they only want payment in full now.

I was so excited.Then...mid-October, I was going through the inspection process, the remediation process (which he did not cure anything, my agent actually was nice enough to cure a plumbing issue for me out of his commission!)

If she were my tenant, I would have already issued a cure or quit because my rental agreement forbids running a business out my apartments.  

Well, price cures all “slowness” but Craigslist is probably your best bet.

We spoke with the tenant, posted a notice to cure/remedy, and then scheduled follow up inspections of the unit to verify, as best as possible, no one else was living there.

If I could contact the previous owners and they release their interests in the property wouldn't that suffice for curing any encumbrances?

You have to properly notice them (In AZ it is called a Cure Notice), which gives them 3 days to correct, or be in violation (Which you can define terms of consequence in the Cure Notice). 

You might not also be able to start taking depreciating the 3rd unit until the unit was ready and available for rent(which appears to be in December in this case).2) I think you are confusing the terminology of a not-for-profit.A not-for-profit's business goals are to provide a benefit some underlying benefit to society(cure a disease, feed the homeless) with no interest in being paid a profit.

In such event, the Landlord may serve Tenant with a seven (7) day written notice of termination, whereupon the Tenant must pay the unpaid rent in full or surrender possession of the premises by the expiration of the seven (7) day notice period.Furthermore, the Tenant may be terminated with three (3) days notice if the Tenant has committed a substantial violation of the Lease Agreement or applicable law that materially affects health and safety, and the violation is not cured prior to the expiration of the three day notice period.

This cured the issue I had.
