In addition to the letter, send e-mail and text stating the same thing.

You might get some push back on this from time to time, but generally when you're dealing with motivated sellers, this isn't their priority.

Particularly sellers who are in some kind of financial distress or are otherwise motivated to sell (probate, foreclosure, job loss, divorce, etc). 

I know you can't blast text people but you can send personal texts to anyone.

Motivated seller helped us get a great price and a few concessions.

While these may be normal landlord issues, I think he has other motives or simply is an overly picky tenant.

If you can negotiate seller financing for the deal and the seller is motivated enough to move the property, then you can build in loan terms to protect you and your investors from the dreaded capital calls because the property is in the red.

I'd post some notices, send some texts, maybe even a FB message - do anything to show that you tried to reach them and they didn't respond: "28 days after it reasonably appears to the landlord that the tenant has abandoned the premises, whichever occurs last."
