It would just need to be a situation where they have great contact with the person doing that managing of the project (I.e. have known the person for years, great reputation, person has experience in flipping etc.).

One of them I have used personally. 

Yikes I am almost afraid to jump in on this one, however, I know Joe personally and he is not a scammer.

A person doesn't have to like these new realities but realities they are none the less.

I personally am interested in creating a long-term rental portfolio but I'd be interested in hearing any strategy, ie. house flipping, short term rentals etc.

Definitely a personal question. 

Personally I pay $300 commission to get the new tenant, 8% of rent collected, and $150 for renewals.

I know some will differ here but I will offer my personal opinion like many others have.

@Travis Timmons thank your for sharing these details in your personal experience.

I do know that unless a person knows what they’re looking for and how to close, it can take a lot of leads to get a deal to the finish line.
