Right, but how do I deliver the news that their lease will not be renewed?

The worst lenders I have dealt with are the ones with underwriters in one time zone and origination department in another, branch manager in another that don’t communicate well with each other and end up over-promising while not being able to deliver.

Those two things have ZERO connection with each other.That is why I responded to the original OP.The effectiveness or accuracy of delivering "DATA" has nothing to do with finding motivated seller leads.

I’m considering having a lawyer send them a certified letter, though I know that will still come with a significant fee, which is still preferable to full service.

How are they delivered?

Quote from @Donna Johnson: Quote from @Judy Foster: we too have tried a small investment in their notes and we got the same letter yesterday. 

Have they delivered on their promises, or have the results been underwhelming?

Check county recordsUse online search tools like PropStream, Reonomy, PropertyShark, etc.Use local GIS mapping tools (ask your county)Search online directories for LLC or TrustTalk to neighborsHire a skip tracerSend a letter to the propertyThere are a lot of options.

In fact, he delivered returns “only” in the 11% ROI range.
