Multiple investors with decades of experience, some GP, some LP, some skeptics about the entire business in general sense and some bulls who have gotten rich from investing have all chimed in on this you got links to specific case studies from Brian Burke, a seasoned syndicator, a guy check from Melanie p, who makes it a part time job taking the trash out and exposing the shenanigans of one syndicator after another.Greg Scott has an excellent reputation on these forums, and provides a counterpoint to Melanie’s skepticism.

You'll never pay them fast enough to make it make sense.

It makes sense in places where it has temperature extremes.

The Exclusive Right to Represent makes sense for prospective individual homebuyers, but for real estate investors, it seems unfair and limiting.

It's just common sense, but not really scalable as a business of its own IMO.   1.)

Single family usually doesn't make much sense from a rent/price ratio in A-B areas unless you are doing a rehab.

PM made a couple attempts to collect and then offered to cover the damage because toilet replacements are not that costly and continuing to pursue the damages did not make sense for them.Airbnb is supposed to cover guest damage but if they refuse to pay for guest damage their insurance has reduced value and cannot be relied upon.

Lastly, the price point is still very cheap here in the sense that you can still find investment deals that hit the 1% rule for 120-180k!

So there are definitely times when owner financing makes sense.
