In either hyperinflation or greater depression,

her lender financing deal is a bad bets.

Hyperinflation: The rent to own renter can force the buy out to leave the owner loose all price rise potential.

Great depression: The renter can default on the lease to purchase agreement to leave the owner stuck on the ever depreciating asset.

To win the bets, one would hope economy to be stable. Do we have a stable economy?
