And if your average review score is 4, they will probably boot you off the platform.  

Your roofs might look good, but they might leak later.

Most articles I've read recommend taking a trip to get boots on the ground.

I have done this and then we lost half of our W2 income, then a big HVAC repair, then the ELOC rate drifted up from 4% to 10%, then a storm forced a roof repair sooner than expected.

They will do a slap dash job on a house that still has a bad roof and foundation in a neighborhood that will see zero appreciation. 

Amortize your major repairs (roof, hvac, built in appliances) and add an estimate for small maintenance.This feels not terrible to me.

Any excess proceeds not applied to the investment portion may be taxable as "boot."

There will undoubtedly be blue tarps on roofs for months and months to come.

You will be competing with people who have 'boots on the ground' and can visit any property owner with short notice.While wholesaling from afar is possible, it is recommended to begin closer to home.

Ex:  A roof in my area cost 9,000 and will last 25 years.  9,000 / 25 yrs is $360 a year.
