As long as the investor does not expose himself to negative cash flow for long periods of time, over any 5 year and definitely 10 year period the real estate market in general should recover enough to provide a positive value change for most real properties.  

Also, focus on 2 years of job/income stability.Class D Properties:Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciationVacancy Est: 20%+ should be used to cover nonpayment, evictions & damages.Tenant Pool: majority will have FICO scores under 560 (almost 30% probability of default), little to no good tradelines, lots of collections & chargeoffs, recent evictions.

Be careful of financial items or “investor hours” and travel.Think this way: “If I did not do this (Insert Task) would be STR be negatively affected”?

They do say they have a one time fee for debt collection and I suppose negative reporting with a 30 day delay and dispute process. 

They have made a lot of false advertising claims that their contract you sign with the program specifically negates so you cannot sue for any reason.

I was raised by "Poor Dad (parents)" who taught me those concepts growing up, and is still mostly their values, but they were also lucky enough to have lived in a time where that worked well enough for them as they retired with a very nice nest egg.

Having an agent to help with negations is also beneficial.

It definitely feels like there is a negative stigma around it.

If that’s the experience I had with wholesalers up until now I would not have a negative view of them.  

It's a fascinating concept and I think offering unique experiences is a great way to stand out in a crowded market.
