I would read up on "Squatters Rights" laws and how long a typical eviction takes to execute.

They want to keep the note long term but want to leverage or recapitalize using hypothecation (similar to #3 on Chris's list but with notes rather than homes). 

Divide the long-term vision into manageable steps.

My biggest aim is to ensure that my long-term success aligns with whoever I invest with's long-term success instead of making their money on the upfront sale and leaving me on my own. 

Then do a thorough research on tenant applicants (note: leaving this to a PM may be hazardous to your financial health) and choose the one that is most “stable” with the best potential for long term tenancy.This advice is contrary to maximization of rental income, but IMO will reduce expenses of tenant turnover, property damage, property management fees so much that the difference in bottom line income will be quite small.  

These small conveniences can save you time and money in the long run.For rent collection, you can try Rent.app, which is easy for tenants to use and keeps everything streamlined.

It doesn't take long to learn how to spot a good deal.6.

This approach does not work on every deal, but if they are doing 1 out of 3-5 deals like this, it really helps the fix & flipper to develop long term wealth, rather than just chasing the next deal for chunks of money. 

I have STR, MTR, and Long term rentals.

While the prices are attractive, I'm concerned with its long term viability.
