I'm sorry to hear about what you're going through, but things will get better! They always do!
In terms of getting started, my best suggestion would be to seek out a mentor that has done what you are interested in doing so that you can bounce ideas and get your questions answered. Are you interested in using hard money for your deals? If so, it might be a good idea to speak with a hard money lender and find out how much you might qualify for and how it might affect your finances before you really start looking at properties to invest in.
Also look for local real estate groups in your area (if available) where you can connect with all types of investors that can provide a wealth of knowledge. Hope that helps! Good luck!
My steps for getting started:
1. Get your financial life in order. This means debt-free and you've got money saved up for your purchases. Don't buy into the hype of no-money-down peddled by get-rich-quick gurus.
2. Start your education with books that provide a solid overview of real estate investing, finding deals, funding deals, and managing rentals.
3. Once you have the basic foundation, build a game plan. This could be as simple as purchasing one single-family home a year. Get a taste for it, gain some experience, and then build a more robust plan later when you have a clue.
4. Get started! You can fill in the blanks as you go. Don't get "paralysis by analysis" waiting until you have complete knowledge of all things real-estate related. Most mom-and-pop investors bought their first property without really knowing what they were doing and they muddled through it and survived. You can do it. Just do it.
