I know that there's some discussion of this topic on BiggerPockets, but one specific issue I don't see being addressed as much as I would like is the repair cost issue when you're wholesaling virtually and therefore can't actually walk the house.I know the general answer is "get boots on the ground," but that, I think, still leaves a lot of questions.

This is clearly specific facts and circumstances based but I’m curious to know whether based on historical returns you would have decided on a go vs. no go on a property when you were on the fence due to these variable assumptions such as repairs and capex and your historical experience is tipping toward a lower % than the assumptions being used when analyzing.
