<prompt> Human: So my girlfriend and I are getting jobs in the San Diego area and she wants to buy a house, preferably Escondido, San Marcos, Vista and Oceanside. She will be making 38kyear in her position and I will make 55kyear.We are both 24 no kids and been renting our whole adult lives.Her credit score is 630she has one medical collection 1k. Mine is about 540 bad credit a couple collection and late payments.Her debt to income ratio is really good shes only 17Mine is not bad but I think its 20 we dont have rent currently as we are staying with my mom and she isnt charging us at all and she provides groceries. We only have the bills we owe. Anyways we want to get a house but we both know my credit isnt good at all but fortunately my GF is decent. Also her Grandparents want to help us out by paying the down payment on what ever house we get. Plus her aunt who has really good credit said she would cosign for the house as well. So my question is what should we do first? Look for a realtor? How does my GF qualify for a FHA loan? Whats the highest loan she can get? What are some things we should be worried?  <response>: Id strongly advise not buying a house with a girlfriend. Disaster waiting to happen.
