If by real estate business you’re implying you have little or no money to invest but are contemplating using one of the guru inspired methods (subject to, “wholesaling” , fix n flip) to create cash flow, I’d encourage you to do research on the true success/failure rate of people who engage in these endeavors, the amount of money the successful operators spend monthly on marketing, and the real time commitment and knowledge and experience necessary for success.  

Active engagement in the Real Estate industry.Flipper    Builder  Lender  Syndicator  PM  Agent/Broker etc etc.Here you create your own income streams by working the business its a business its not just being a passive investor of cash flow assets..

I'll say, it's a good sign that the founder/owner is willing to engage questions.

If you engage in a real estate investment program as a means to build wealth, you are going to incur a significant amount of debt early on and likely for the next 30 years, as your holding grow.  

They may even engage in intense, detailed negotiations.

Ask the investor what are his numbers, what does he intend to do with the property, how much is it worth when done, how much does it need in repairs and what repairs will he or she be doing.When you know your market inside out you will feel more confident on moving forward.

That said I'm not 100% confident in this answer so take it with a grain of salt.

Your insight gives me more confidence to invest.
