Buying my deceased grandparents house

[Andrew Scott]

Hi all,

My grandmother passed away last year, and I'm buying the house that they built in 1965. It's also the house my mother and her siblings grew up in. They've spent the last year being nostalgic about the place...having sleepovers and whatnot. And they can continue doing that for as long as they want (within reason). However; I'd like to go ahead and buy it now while rates are still low. They had an attorney take care of probating the will, and selling the house is the only thing left. Everything passed to them equally including the house, and they are each co-executors.

 My lender said I'll need to have a contract signed before I can lock the rate. My question is on the contract, do we write in my mother and her siblings as the Seller, or "the Estate of Grandmom" as the seller? I don't think the title has been put into each of their names, as the appraisal district still listed it with Grandmom's name, and mail is addressed to the "estate of Grandmom". This is located in Texas.

I know this is a question for the attorney, but he's very expensive and would charge a whopping amount for this simple answer over a 1 minute phone call.

Thank you!
