Why don't THEY buy it themselves? (a Q re: Turnkey 'deals')

[Chris Collins]

My question is this, and it applies to Turnkey companies, as well as other investors selling properties.

"Why don't they buy it themselves if its such a great deal/ROI?"

If a turnkey company actually believes in the product they're marketing as a great ROI for the potential client and has such great cash flow potential, why don't they just get a loan and put the 20% down on the property themselves? Why sell it and get their small 1-time commission?

Thanks,
