Call owners directly and send letters/mailers.  

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – so, they often select the first PMC they call or that calls them back!

@Kyle Carter, The strategy you're looking at would be what is called a "consolidation exchange". followed by a conversion to your primary residence. 

Letters, post cards even calls are useless to this owner class. 

I asked a lender company through BiggerPockets to call me.

My best recommendation would be to find someone who is doing something similar to what you hope to do in the space and have a coaching call or two.

Also there is a new thing called "novation" and I am not an expert on this and can't comment on it.

The buyer of course believing he had purchased the house paid a visit to the tenant, who of course called me.  

finally a guy who knows this guy and calls him a scammer haha.
