Joint Loans for Unmarried People

We aren't married. How do we buy a house together?

Basically, the same way that married people do. The qualifications are exactly the same, provided that you both will be living in the property. If not all of the people who will be buying will also be living in the property, they have to show that they can afford both the place where they are living and their share of the expenses of the property. The only real difference in the paperwork is that unmarried parties cannot submit a single loan application - they must fill out separate applications. Most lenders will require that all of the disclosures also be signed and submitted individually. But that's just to keep the lumberjacks happy killing trees.

Now it is highly advisable that you consult an attorney as to how you want to hold title, and that there be some kind of partnership agreement that gives the other parties rights to recover any extra they paid to keep the partnership out of trouble, if one or more of the partners can not or do not make their share of the payments on time. But that's not a part of the purchase process, and you can certainly buy a property with basically anyone. It's one of the most basic of rights here in the United States. Convicted felons, jail inmates, illegal aliens, and people who have never set foot in the United States can all buy property here, as long as they have the money or can persuade someone to lend it to them.

The fact that people are not married means basically nothing to the loan qualification process, either. The guidelines are exactly the same either way. Yes, there are complex variables as to how you qualify, and what loan you qualify for. But people who are married but aren't going to be living together are treated the same as two random business partners, except that they can put all of their joint information on one application. You can have any number of people on title to a property, or responsible for a mortgage. The major thing to watch out for is that they must qualify as a group, and almost always under the same set of qualifications. If one person has to do stated income, they all might as well be stated income, because they're not going to get full documentation rates anyway.
