My recommended next steps are:
0. Set goals. Clearly outline what you want to accomplish, by when, and why. This will keep you focused.
1. Get educated by digging into the resources above. This will take time to build your comfort level.
2. Start connecting with others who currently do what you aspire to do. Understand how you can help them and/or obtain guidance on how to get started.
3. Build a team of brokers, lenders, and property managers.
4. Take daily action: analyze deals, make offers, talk to owners/investors/brokers, drive for prospects, help others. Whatever it is just focus on taking meaningful action every day toward your goals. The power of small daily action is tremendous.
