Taxes, Fees Incurred Selling Mom’s House

[Ana Marie B.]

Hi BP Fam! Have a situation where my mom and her siblings are looking to sell their elderly mother’s single family house (who is alive and moving to a care home).

There is a living trust in place. Wondering what sort of taxes and fees they will incur as a result of selling this house? 

House is located just outside of San Francisco. Bought for $79k in the 1970s and now worth around $1M. 

PS - I would be interested in buying this house, but there are some family issues around jealousy, etc. and my mom won’t inform her siblings of my ability to purchase. Owner finance is tough with grandma’s mental state.

Any advice/input is appreciated. Thanks!
