How does pml get paid back from buy and holds

[Kenny Lewis]

Want to get a better understanding about paying back a pml from a rental property buy. I know for flips that once the property sells that the pml gets paid back from the sale price. But how would I pay a lender back with a rental property since I won't have the purchase amount back with a sale. What's the process? Is it monthly with the cash flow of the property? Advice for pursuading a lender to invest in rental property when the lender wants to be paid back quickly or full payment...
