Almost $500k for a house (albeit a large one) in vacaville still seems quite high. This house looks like it is on an end lot near the road as well which reduces it’s appeal (to me).

But, if YOU like it, are not in a toxic loan and can afford the payments, go for it. However, you need to be psychologically prepared to be paying on a house that is worth less than you owe for it cause that could happen quickly.
