@Terry Hershberger is on the money ... here is my thought:
Alyssa, start saving. Whatever your rent is, figure you can have a nicer or equal place for what you are paying in rent. Like Terry said, go start talking with community banks, and most importantly (community or not), banks that do their loan underwriting IN HOUSE. This is vital. You go several months chatting with bankers while you are saving like a mad woman. Once you find the right fit you explain to the highest person in charge (and I would suggest dressing in your best professional outfit and setting a meeting with the highest person at the bank) and explain that you are a real estate investor, currently working with other investors, but looking to group your business.
Next, you explain you have $2, or $3, or $5k, (this is important) to put into the bank, and its part of your current money. The banker will say they appreciate having all people, and yes, its nice you have deposits. You explain you will have thousands more as you grow your salon business, as well as your real estate business.
Step Three, buy a house/duplex. Make sure the bank does FHA loans, or something similar, unless you want to be prepared to do 20% down ... make sure you understand exactly how they structure their loans, and be ready to make a move once you have the funds to do it. If you get a duplex, get the best renter possible, and pay your rent just as you were, paying yourself, and letting the tenant pay your mortgage/utilities.
Now you own a property, you have established a relationship with the bank ... and you have your first "deal" under your belt...
Go get em!
