Alazar,
I recommend that you tell everyone that you interact with that you are a real estate investor and tell them what kind of properties you are looking for. Everyone knows someone and you would be surprised how quickly you can start getting leads. To increase the effort others put into building my business I offer a 1,000 referral fee to anyone who tells me about an unlisted property that I buy. This has worked well for me. As suggested you can also knock on doors located next to properties that look like they meet your criteria for buying. For me I focus on distressed properties so they are pretty easy to spot.
Whenever you buy and rehab a house make sure you talk to the neighbors and tell them that you are always looking for more properties. If they see what you do to a distressed house in their neighborhood they will be a great advocate for you going forward. I've got many deals from people that lived next to houses I have rehabbed.
Oh, and just my two cents Never buy a property with the intent to break even, even if you are just trying to learn more about the business. You can learn the business while making money too and it is a lot more fun. You are in the real estate investment Business and as such the numbers will have to make sense for you to get involved. People will understand that. Good luck.
