That's just one example of how the technical aspects mesh with government aspects.Even marketing, being able to sell lots, is useful as is being able to get along with others and assess their abilities and motivate them to be part of your team either as employees, vendors, financial supporters, etc., all come into play. 

Our idea so far is a sort of poison pill clause that "if one tenant moves out, landlord reserves the right to cancel or renegotiate the lease" or something along those lines.

This scenario comes up during our continuing education courses to renew our agents license, but Im sure many agents don't think about this sort of thing when showing houses.

Consider working with a list broker who can make some recommendations for some of the new motivated owner occupied lists like; Seniors with Long-Time Ownership and Owners with Low Financial Stability Scores (FSS)

Laughable all the same.When tenants hear that sort of line I know exactly what they are thinking..........."

If they are paying, you can buy a few similar notes and hypothecate or borrow against their value, sort of a BRRRR, though you still don't have a deed, you just have a promise to pay and an encumbrance or lien on the property that will be eventually paid off & now you have a loan to pay back from the homeowner payments.If it's not paying, you will have to foreclose or get them to deed the house to you. 

Is that a requirement or does that provide some sort of benefit?

These are people who share motivational characteristics of people ready to sell, but haven't yet done all the work they think they need to list property. 

I would mostly like to motivate him to take care of it himself, but I would like the pricing to be somewhat reasonable as well.
