“Buying Out” your PMI with a slightly higher interest rate - Usually, the rate bump is around half a percentage point, meaning that the borrower pays about .5% more on his mortgage than he otherwise might in exchange for dodging PMI.

Sometimes the marketing says no MI but its baked into the rate, or the seller is paying for it through seller credit or single (one time) premium, or its lender paid (via higher rate).The other way is the borrower just pays it monthly, split premium, or single premium as well.

You didn't make the choice to borrower from your future self in order to have gratification now.

Or borrowing money from a private source?

Right now assuming 5% borrowing rate. 

Debt service will be about $500/month for each $100k they're borrowing.
