Hey @Josh Ball, so unique for unique's sake could be hit or miss.

Hi,Unique scenario.

Any laws against repaying the loan in stocks instead of actual cash?

Like Jay said, there can be more flexibility in repayment options. 

In this situation we have a former-tenant  hyper sensitive to return of full security deposit (when unit wasn’t returned in good condition) and we are  experiencing a few unique damages.

Real estate transactions with non-profit organizations like nursing homes or religious entities can indeed be unique, but they’re often manageable with the right approach.

Early repayment will mean a 2% fee being assessed. 

.: Quote from @Jennifer Turner: Has anyone ever sold a property with seller financing then later extended the repayment period or modified the terms of the loan with the buyers?

Not only do they not repay funds, they claim we owe them additional funding for renovations that never actually happen. 

First step for you is to study investing in income properties.Generally a rental property will have in the range of 4% -50% of rental income going toward expenses to maintain the investment before debt repayment (mortgage).
