However, I talked to someone recently who made $1000 in a week walking dogs through one of those dog services that has an app.

Jonathan reassured me of the value RDU could provide through personal connection and high quality service.

@Andrew LeBaron - which skiptrace or list service are you utilizing?

I don't wholesale but from what I've read on BP some people get $3500 a deal and do one a month and others get $20k on a regular basis and do 3 or 4 a month.

When several of our multi's were originally purchased & had lower rents, we had a woman from a random social services group, (had the ID badge # etc) ask a LOT of questions about the properties.

Your service you provide is housing and that's it. 

I am interested in wholesaling vacant land, however I struggle w/ the math portion as far as understanding how to determine your offering price...I'm sure its similar to regular wholesaling property, but how much difference in price would it be, what is the best math formula to use?

I have two managers (one in state, one out) that are my agents under law and both manage multiple properties with continuous input, regular oversight and ultimate final decision making authority from me. 

I typically don't include a washer and dryer with my units, because they can be a service nightmare.

Its doubtful they will be willing to pay the increased rent (they obviously like the size and price as is).If you are splitting the electrical service, its very, very likely the entire electrical system will need to be brought up to current code.
