You should check out Lisa Phillips 30k And Under RealEstates Investing blogs and videos here on BiggerPockets or on youtube.

Check out the blog, ask questions, and be sure to check out the resources area too.

I discovered this great site awhile back verifying info I heard in a Sean Terry podcast.

Spend some quality time on the new bat site; listen to pod cast, read blogs and forums. 

I would follow all of the above suggestions and discover what niche fits your investing/personality/goals the best.

I had a similar situation and discovered this.

I would try using this calculator and input conservative numbers for your pro forma rents, repair budget, taxes, insurance, vacancy, and other misc costs.Also, I was listening to the blog, reading posts, and previewed 100 homes over a 6 months process before I pulled the trigger.

Bigger Pockets is a great start and there's a wealth of information to be found through the forums and blogs.

Make sure to listen to all the BP podcasts, read the articles on the main blog and be active in these forums to learn a ton very quickly about any topic in real estate you want to know more about.This is also a great place to meet people that can be assets to your business.
