<prompt> Human: Hello PF,I am looking to purchase a house in US with my girl friend. We will both put down our names on the house. However, GF will be the one with down payments. She is Canadian so she is going to bring the money from Canada.Not sure how this will work. Is there going to be any tax complications? She paid tax on all cash and are all legal. Wasnt sure if we have to pay tax on the money once it arrives in US to be used as down payment.Thank you.Edit:To make things more clear..1. We are getting married soon. Already have a child between us.2. Her name will go under mortgage as well. However she does not work right now. I am the sole income of the family.3. She will be transferring money from her Canada account to US checking account. Wondering if I have to put my name on this account like joint account?I am thinking we are good as long as my name and her name are under all accountsmortgage... no?  <response>: Dont ever buy a home with a girlfriend. If things go south youll be stuck with it. Just rent if you absolutely must live together.
