It's an open mishna on BM 65a.  "One may add to rent but not to
a sale price".  The gemara explains that this is because rent is
not due until the end of the period, whereas the price of a sale
is due as soon as the property transfers.

The scheme with the rental property is in SA Harav, Ribbis 50.
