Because I didn’t anticipate such a time delay on the one I’m buying - only became aware of this recently when trying to set a closing date that could happen reasonably close to my sale (a month or so at most). Had previously worked out both to coincide but now the added delay makes the sale more precarious since I’ll be out of the market altogether on a still uncertain timeline.Why on earth did you agree to sell your house?
If you don't need to sell your house, you should have bought the new house first and then put your own on the market.
It's not fair to pull out of the sale of yours as the buyers have plans around it.
So go ahead with the sale and rent somewhere for the period.
