That doesn't cure the nonpayment of late fee, so you still have cause for termination.However, if the landlord decides to proceed with termination on that basis alone, the tenant has at minimum 38 days before being evicted (can't give notice earlier than 8 days after due date + you must give 30 days notice) which means there's virtually no chance you're getting a rent check for the next month's rent.

I hurried up and sold it to him before he had a chance to change his mind....

If you have the chance to look up investor clubs then I would highly recommend attending some meetings to meet other investors and vendors here locally.  

I got the sense (since I am in sales) that they panicked when I said I want to stall, which means there is a chance I can find another lender, etc.

@Chance Noffsinger what was the original reason why you received the 15 year mortgage?  

If the CLTV was below 50% a 2nd position might be fine.Ironically, chances are everything would work out just fine no matter how many guidelines you violate, but you just can't count on it. 

Fun fact...if you see your resident list their father's work number on their application for the emergency contact, your chances of collecting that debt drastically increases!

My biggest concern is the same no cause eviction + moving fee would also be applied to the End of the Lease if the landlord doesn't offer a chance for renewal.

What is the chance of sponsors actually deliver the promised %?

Stuff moves fast around here, so be sure to understand your buy box, rehab and exit strategy and, perhaps most importantly, be ready to pull the trigger when something fits because chances are if you like it, someone else will too.
