The condition period is where most of the time sits. Your lender needs the financing condition window to underwrite and appraise, and a home inspection, typically $400 to $600, needs to happen and be reviewed before you can responsibly waive that protection.
Once the offer is firm, your lawyer and the buyer's lawyer coordinate the ISC title search, mortgage discharge and payout figures, then set possession day, which is when keys and funds actually change hands rather than when the contract was signed.
A seller with a flexible possession date and a buyer with financing already arranged can close faster than a file working through both conditions from a standing start. Get your hand-reviewed valuation from Joel Dyck.
