The other siblings owned and borrowed against the house.

Skip trace reports may provide info or clues about offsprings, siblings and common relatives and associates.

Contractor found the deal, was part on an estate, I had to walk the seller through the courthouse proceedings because it was part of an estate with 7 siblings that needed to sign off.

In a situation where there are multiple owners (it doesn't matter if they are heirs, siblings, spouses, or just several unrelated friends or partners who own the property), the only real questions you have to answer (aside from whether it's a good investment) are "Who owns it?"

., who are contacting me 'because [son/sibling/parent etc] is busy' (or sometimes away).

I'm curious if anyone has experience partnering with siblings?

Honestly with all the tactics you mentioned and the siblings contacting you etc, it sounds pretty similar to that.

I have three siblings, so each of us were entitled to 25% each.

Additionally, my uncle has brought up his estate and making sure all his siblings and nieces and nephews (including me) get a fair shake should he pass down the road (he’s 75).What’s the best way to deal with a partner passing and paying his estate for his equity because I don’t want to do business with his executor?

Even if only one name is on the deed/ LLC that doesn't mean they don't have a spouse/ siblings to contend with to discuss the sale...
