While that isn't always easy, in real estate operations and dealings, it is easy......just understand, it's not easy.Find your buyers first, then you could go through lists, mail for interest in selling, if they are, match what they have to your customer's needs, if you have a hit, go talk to them, if they don't meet buyer's needs, put them in a slot for future contacts when you find a buyer interested in that type of property.

Anyone remember playing the penny slots there with other kids way back then?

Next they'll create a sense of urgency saying there are only a few slots available and just because you apply, doesn't mean you will be selected.

Yes, my 401k doesn't send me a check every month, but it returns 6.5% annually and will pay out like a slot machine in my retirement.

Let me put it to you this way, in Las Vegas you can chose to gamble on many different slot machines, all of which the casino keeps a percentage of every dollar poured into the machine. 

This also allows the existing coin slots to be used so if the card reader or wireless has a problem you can still run. 

@William S. lots of large wholesalers and flippers hire assistants that are paid base + commission.Mostly cold calling work though, which is tedious.

We only had to remove lots of plaster in the bath ceilings to fish up the risers, and cut a slot behind the run of cabs and appliances in the kitchen.But finding someone willing to do this kind of work may not be easy, since it's not as simple as just wiring open studs and letting someone else worry about closing up.

Ensure that all holes or slots in panel are open so proper air circulation is acheived.

@Kelly DeWinter that is interesting but I still don’t know how to get them to work since they have a card slot on them.
