Who would I talk to about multi-person home ownership?

I am looking to buy a home but the only way I can afford it is to have a family member basically go in "halves" with me. I have spoken with numerous agents but all they want to do is sell me house. They give me no info on how to go about owning a home with someone else. I don't have much of a down and my family member would provide a healthy down so I can have mortgage payments that I can afford. Should I decide to sell, they would get their investment back. How do I go about this? Who do I contact? The only info I have found on the web relates to vacation and second homes. I would be a first time buyer. HELP!

A title company such as First American, Old Repiblic, Stewart Title, Fidelity National. You'll need to contact a loan officer for the mortgage payments. If you live in Southern California email me at aurora_sarkissian@yahoo.com. Good luck!
