The property owner uses the money to pay off as much of the mortgage as possible. 

I cannot think of a way that you (the LL who stands to "benefit" by them repairing their own space that they are paying you to use) will come across in a positive way.Plus, the tenant who incurred damage due to the other tenant's leak, may have some legal rights to have the tenant with the leaking pipes pay for the repair in both spaces.Now, beyond the legal side, you also need cognizant that most mom and pop tenants (which I assume these are) are not great with their money.  

They lend you the money you need to buy their house.Subject to - you buy the house subject to the existing mortgage.
