<prompt> Human: My grandmother wants to buy a home. But she doesnt qualify for the mortgage. She is now asking my sister and I to put the house under our name. I am recently married and trying to start my family. Can this ruin me financially? What will this do to my future? What are the pros and cons? Are there any alternatives to the situation?  <response>: If your grandmother cannot take a mortgage out on her own, the lender has made the determination that she likely cannot pay the mortgage back. Being a cosigner means you would be 100 financially liable if she were to default, so yes this can absolutely ruin you.Do not cosign this loan, and make sure your sister does not cosign this loan.
