Transferring title to relative

[Shawn Strain]

Hello everybody! My name is Shawn Strain, I am from southern New Mexico! 

My parents moved to a new town a few years ago, but didn’t have the credit to purchase the home they wanted. In order to get their house my grandparents bought the house for them, and my parents have been making payments on it. Basically my grandparents have been treating this as a second residence, while my parents make the payments and all taxes.

Now that my dads credit is better he would like to take over the deed to the house. 

They went to a lawyer and a mortgage contract was brought up? I am not too familiar with this process. I figured some kind of seller financing deal would make most sense. But would like to get an opinion from you all! 

Thanks again! 

Shawn
