I’m sorry your house sold for less than you were anticipating. Realtors usually have their ear to the ground and know if the offer is a good/fair one or not.
With your known portion of the equity, down payment, you can now determine how much of a mortgage you can be approved for. Hopefully, the lesser selling price doesn’t hamper things too much.

Feelings are fleeting. Be better, not bitter. Love the person, forgive the sin.
