Properties with garages (especially those located near highways and main roads) can generate at least $400/month per garage space.

Or are cash generators.  

Then it is a win-win-win situation, investor wins because he does not have to go do a lot of research , invest smaller amounts, get a single K-1, sponsor wins because he can raise larger amounts from a single fund of funds entity and fund manager wins by generating income from the spread.

It also saves you the time from having to do the task so you can have time to do other things that generate a higher revenue / per hour.

Meanwhile hardly any emphasis is placed on the loan administration and even more importantly the relationship component of lending.Far too many investors, particularly those just starting out, are being conditioned to seek out the “easy” lending choice rather than invest time and energy required to cultivate meaningful relationships with lenders who truly value the borrower/lender relationship and are interested in assisting you grow.

Investment income can probably count as well but I'm guessing they would look at your last couple years taxes to see how much income it generates.

From what I've seen though it could be a great way to generate solid cashflow which could fuel an investment strategy. 

Yes, it's just a melding of 2 common things; Turn-Key and Seller Financing, both of which have been around for generations. 

How come more landlords and flippers aren't recording evictions and posting to YouTube to generate revenue?
