This comes up when a seller's own purchase or move does not line up neatly with the sale's possession date. Rather than force a rushed move, both sides agree in writing to a short overlap, with the seller effectively renting back the home from the new owner, under a contract a Law Society of Saskatchewan-regulated lawyer reviews before it is signed.
That same lawyer, part of the closing process that runs $800 to $1,500 in legal fees on a typical Saskatoon sale, drafts or reviews the terms: the rent amount, the end date, who covers utilities and insurance during the overlap, and what happens if the seller does not vacate on time.
It is a useful tool for a tight timeline, but only when it is in writing and reviewed before possession day, not agreed on a handshake. Get your hand-reviewed valuation from Joel Dyck.
