Its kind of hard to find a place where an investor hasn't gotten ahold of yet.
At the same time your not the same person.
For instance. When I go to areas or neighborhoods I am interested in. I will just talk to random people working in their yard or what have you.(assuming they don't look to busy or come off as angry or irritable) I tell them I am interested in buying property in the area and then just chat for a minute and give them my card.
My most recent deal worked out this way. I had one woman tell me about her and her husband getting a divorce about a year ago and was looking to get a different home. (too many bad memories) She said that she had talk to a few people about selling the house but stopped because they seemed "sleazy". She took a card and we sat down and talk at her house the next week. We were able to work out a deal and are closing on the home in about 2 weeks. Obviously I am not the most seasoned of best investor out there. However, me and this woman were able to work out everything just because I seemed genuine and simply took the time to talk to her while I was in her area.
Let everyone that you know, know that your an investor. Talk to bankers, realtors, brokers, handymen, even other investors! Anyone that might help you down the road and develop a relationship with them. If they know your serious they will be sure to help you down the road. Go into the neighborhoods you drive in. Talk to people give out cards. If you are genuine it shows and people will take to that.
Also how much money do you have to invest with? What is your credit looking like? Want to make sure to build those up so that when you do start to make relationships with agents and bankers they know you can close on a deal. If they know that they will be more confident to call you with possible deals.
Theres a lot more, but in short don't focus on other investors so much. Deals are out there for everyone. Focus on yourself and your relationships with professionals and other investors and go from there.
Good luck!
