I believe there is a younger sibling but Im not sure if there are more.

My grandmother passed away and now my father and his siblings own the house.

If you can't locate children, then go wide and try to find siblings or their children.

I have a sibling who was awarded a large sum of money in a lawsuit.

Can anyone put me in the right direction of tapping into this equity to reinvest it in a rental property for me and my siblings to house hack in Sandiego, my whole family understands the immense benefits and is on board, I just want to see if it will be efficient or if using the equity of the house will come back to bite me.

Siblings?

If you could rehab for 100k to add 100k in value, you'd be working for free...there is a lot of work unless you hire a gc 101% trustworthy...for the opportunity to hold the property, be responsible for loan, taxes, insurance and upkeep and take the risk of another hurricane (or fire or other low probability but very expensive incident) or low occupancy and negative cashflow or partners (siblings) not playing fair or wanting out or even you wanting out in a down market with only 20% equity and no buyers.

The 5th bedroom allows two siblings plus kids and the grandparents to have a pleasant vacation.

Two siblings purchased the property years ago only adding one to title, but a year ago the one not on title moved in.Any way around waiting an additional two years if a quitclaim deed is now completed.

My 3 siblings just received their 1099's for 53,300 each.
