You have to create value....in your ideas Learn a specific market/niche and present your knowledge base here on bigger pockets. If you can create value for an investor in your market or any market they will be more likely to give you guidance and or partner. Forget about your less than desirable credit (WORK ON IT) and don't use it as a stumbling block but a lesson never to repeat.
You have to think about your market or a market and learn the ins and outs until you can sit in front anyone and make them believe that you can be there boots on the ground, their go to guy in the area. That's how you create value and how you can start in this business with no or low money and or poor personal credit.
Start working on business credit and at least you have another avenue for credit. There are lenders who will lend to your business without a personal guarantee from your personal credit. Harder to achieve but doable. I'm working that angle now... Network, go to the local REI meet ups and talk with like minded people. This is a good place to bring your knowledge about a particular market too. Investors attend these meet ups all the time.
Keep your head up and project "business man" not a guy who is looking to find his way. "fake it to you make it." People believe what you project and you have to vision yourself as a successful real estate investor, and you will be. Nobody can't tell me I'm not a multi-millionare!!!!! And I don't have a single property under my belt LOL! But ask me about my market, and you'll think I've been investing for years! We all start from point A.
I'd be happy to share my route with you, PM me as I may have personal experiences that may help you along the way!!! You have to be in it, to win it.
