You will have to do an LP unless they qualify under the securities laws.

For future deals, only pay security deposit, inspection, appraisal, and engineer cost up front. 

See what contracts he/she uses in order to secure deals.

What is the security the lender has on these deals? 

For example, maybe tenant couldn't pay rent one month and landlord agreed to use security deposit for rent.

And stepping outside that box is a risky thing these days.So you'll need to watch out for that as well as the extra level of protections necessary to secure the property for you and either provide a profit incentive to the unrelated party or protect them from a taxable event.

---------------------------------------------Understood, but as a seller, I run the risk of some technical breach of the buyer's contract that allows him to void  his own escalated bid, which means that in chasing after your $500 increase, I blew my chance to sell to a solid offer for $275,000.

If you are under value you should NOT reduce your rent.Good tenants are typically good pet owners.In our state we can accept a pet deposit (which I make refundable) and we can charge pet rent.I would keep the rent the same, lock them in for another year and offer them a pet addendum with an additional security deposit (100% refundable) and some pet rent.
