The mortgage valuation (done by computer algorithm, not an in-person visit) valued the house I’m buying at 525k. I’m paying 575k. I’m minded to stick with it, and not risk renegotiating, as the house suits us and is a good school. But, at the same time, I’m feeling worried I’m throwing money away. Have you ever experienced such a big gap between valuation and actual price you were paying? Thanks.
