<prompt> Human: My girlfriend of two years and I are looking to buy our first home. She is a 25 year old making around 45,000 with no debt and a modest car loan. She starts her masters program in the spring so income should fall to around 28-35,000. The schooling is payed for by her employer. I am a 27 year old senior in college making around 25,000 with no debt, other than deferred school loans less than 10,000. Looking to buy a house with an efficiency to rent out. How should the mortgage be set up. She has suggested it all be in her name and I pay rent, due to the volatility of young relationships and my lower income. How much can we afford? I know the latter is a tough question to answer, let me know if any more information is desired.Edit: 40,000 in savings.Assistant: Unless you guys are actually planning to be married soon, Id stay away co-signing on a mortgage. In fact, if you are planning to marry soon, Id just wait until then and use that extra time to save up for a nice down payment you didnt mention how much either of you have in savings.Also, youve got some other things going on that Id personally want to wrap up before going down this road. Youre going to be hit with student loan payments pretty soon. Shes just started a masters program, has reduced income, and is paying off a car.Human: Currently paying rent of near 700 for a studio apartment. The plan is with renting out the efficiency we can live near rent free not including taxes and have something to show for it.  <response>: I just wanted to say that I havent heard of it being possible to buy a large property, rent out 1 room, and have that rented out room pay for the whole property.It sounds like you are massively underestimating the cost of buying this house.
