First of all welcome to Bigger Pockets.
Having purchased 2 homes you probably have as much experience as some of the RE gurus out there. Bigger Pockets is a great place to learn about REI. You can attend REI groups in your area as well some of them are very good and some are highly commercialized.
Starting out with limited capital is very challenging for a newbie even more challenging if your credit is poor. Challenging because it hard to attract partners with no experience. As a newbie you may not be familiar with some of the creative strategies that might close a deal with little cash. Also financing can be a greater issue.
You may want to network with others here that may have started in a similar position and find out how they overcame this.
