I'm in an extremely fortunate position where my Mom, upon learning about current mortgage rates and why I haven't bought a house yet, wants to essentially be my bank to buy a house. As in, she wants to fund the house, put it in my name, and I pay her a reasonable down payment and pay a "mortgage" to her at 2-3%. So what would be the best way to do this?She buys the house then transfers the deed? Should she just transfer the cash and I purchase it?

Side note: I know people are usually against doing big purchases with family, but I don't really see a downside since the house will be in my name, and with that 2-3% rate, the payments will be similar to my rent even considering maintenance and property tax.
