If you do decide to help them out and rent continues to be late simply have a talk wiht them and remind them that rent helps pay your bills and since you did them a solid ask for the same in return.  

@Nicholas DillonI concur with @Vessi Kapoulian comments.Promised or projected returns do not mean actual returns.

This deal leveraged strategic financing, value-add renovations, and market knowledge to deliver a strong return.

The deal did not go through and they never returned my money.

In the event your property does not sell, pivoting to a rental could be your best option and allow you to maximize return.

In general, the higher valuation properties with views or close proximity to water have higher rates of returns.

This means that you will probably need to pay registration and filing fees in at least 2 states if you don’t buy CA property as a CA resident.Be sure to tell your accountant that you may now need to file non-resident income tax returns in each state where you own property as well.

I haven't heard of that company, but if you are looking for done-for-you real estate investing then just know that your returns are going to be significantly lower.

You can certainly find a property for cash flow that may also bring you a strong return on that investment.

This should include potential rental income, expenses (including property taxes, insurance, maintenance, and potential vacancy), and your expected return on investment.
