Partnership can lead to a lot of headaches in the future especially if you don't have a prolonged history of trust with the individual. Since you served in the Marine Corp aren't you eligible for a VA loan?
If you can find a lender that can qualify you why not buy a multi-family investment (duplex, triplex, quadruplex) and house-hack it to renters while you live in one unit?
Also, you should be very careful before going into real estate with no money. Even with a partner, how are you going to save yourself from repair costs that may come up or disputes between you, your renters, or your partner?
Real estate is a long-term play and the worst thing you can do is to set yourself up for disaster in the beginning. If you are really knowledgeable in investments, I would take a year or 2 or however long it takes you to comfortably afford a home and not have an anxious conscious about constantly trying to keep your head above water.
Stay ambitious but patient,
Best of luck,
