The results you got don’t look surprising to me at all.
BUT be alerted…since you are divorced and remarried, and there is also a non-custodial parent, the net price calculators will only be a decent estimate IF they actually ask about your marital status, AND get info from the non-custodial parent where required. Otherwise…don’t really expect them to be accurate in your situation.
Yes…schools consider home equity in different ways. Yes, some schools consider non-custodial parent and some don’t. Yes, some schools count ALL of the parents and step parents.
If the college has a net price calculator of their own on their website…use that…but again…accuracy will depend on the breadth of questions asked.
