Sorry to hear about this for you, although I don’t really understand how it happened - real estate transactions seem so different in the US than here in Canada. Did you at least get the deal you wanted on your sale? I’m a little confused there too, that anything is still being negotiated. Here, all stipulations must be written into the offer and it’s DONE once conditions are removed and the deal is firm - usually 30 to 60 days prior to possession. If a buyer can’t or won’t close at that point, the entire deposit is forfeit. I wish you well.
We closed on our new place on Sept. 6 and ran a quick reno before moving in, which turned out to be a nail-biter, with labour and material shortages. Possession on our sale was this past Monday. Everything got done, but boy - moving was easier that last time we did it. We’re getting too old for this ...
