Seller doesn't want to sell to LLC

[Ahsan Faheem]

Me and my friend/contractor put a all cash offer to buy my neighbor's house in Los Angeles. I created a LLC for which me and my friend are 50% owners. We have a proper operating agreement. provided proof of funds and offer letter. Everything was provided to the seller the way she wanted

After 2 weeks of silence, seller is saying they don't want to sell their home to a LLC. they will sell if both of us are buyers

What is the best way to do this transaction ?

What is additional cost of moving the title from us to the LLC ?

is this a big deal or easy fix ?
