You get a captive audience that discount all apartments that don't have them. 

These are the people that are riding the chair lifts every day and have a captive audience with whom ever they happen to sit next to. 

I have gotten a few business cards and contact info (not REI related), however, if I felt like I was being solicited, in a captive environment nonetheless, I think I may complain to Uber/Lyft about said driver.  

Refrain from having speakers try to upsell a captive audience.

About two years ago my accountant mentioned "Captive Insurance" as a way to avoid paying a lot of taxes.

But at least you have some captive renters, in theory.

As the tenants pay off the MH you can then slowly raise rent as well B/C they now own them and there is no place to take them you have a captive audience. 

Seeing a home in its worst state, and then watching someone renovate and practically make a whole street better is just captivating to me.

Then, in theory, you can pull your money out and let the rent income pay down the mortgage without any of your investment capital being held captive in the property.If I am off base someone please let me know.

so we will be looking forward to hearing back from you after the freebie, but I really want to caution everybody about how easy it is to get sucked up into seminar hype when their audience is 'captive' meaning all the information is controlled and filtered to ensure that their promoted services and products always come up roses and "I'd better buy NOW otherwise the opportunity will be lost forever"!
