@John R Bongiovanni Aside from those services, I have done a lower security deposit in exchange for a higher rent on a long term tenant and they were fine with that.

Why not 30 year term with a conventional loan?  

If you have scorable US credit, you'll get better terms.

Overpromising and under-delivering in terms of expectations at times.

In some cases, federal tax credits like those for low-income housing or economic development might also apply if the project aligns with certain goals.Instead of buying the land outright, developers often lease it from the tribe, which can reduce upfront costs and sometimes come with favorable lease terms.

On the bright side, you kept your integrity and made a genuine effort—something they sadly missed out on appreciating.

I wouldn’t want to hold the loan for too long, so ideally it would be a 5 year term, presumably ballon payment at the end.

Rent would probably be a short term nightly basis. 

These low interest rates make financing property purchases more affordable and appealing, enabling investors to secure favorable mortgage terms.2.

If you don't want that, I would sell it or put it into storage (which may not be financially feasible), but long-term renters are hard on furniture that is not theirs.
