Last I talked with CoinMax, they didn't do service plans if your complex has fewer than 100 (or maybe it was 25) units in one place. Otherwise it wasn't worth their time and effort to service it, etc. They may have a program to help smaller companies but I doubt it gets a lot of attention.
[size=18]If you want to make money on W/D, let's run some numbers on buying the appliances and installing them yourself:[/size]
Install used W/D set ($200-$300 total) and charge $10/month for unlimited use as an option per rentable unit. Most tenants will pay that amount to avoid having to go to the laundromat. Make sure they also pay the utilities (depends on how utilities are metered in the building) or you'll lose money.
By doing this in a 4-unit complex for one year with 100% participation, you would receive revenues of 4units*$10/mo*12mo = $480/yr. Discount that cash flow at 8% (just for kicks) = $460.02 present value. If you pay out $300 for used appliances, your net present value = 460-300 = $160 NPV in the first year.
Now, because I'm a nerd, look at the useful life of these appliances. Let's say these pieces of junk will last for 3 years before they require maintenance. Then PV of cash flows from tenants = $480*3yrs = $1,640, discounted = $1,278 - initial investment $300 = $978 NPV. If you therefore expect (in PV terms) to spend less than this amount in unforseen expenses (like repairs!), you will make your minimum return of 8%.

NOTE: That doesn't mean you will make $978[/u]...it means that you will make an 8% return on your initial investment PLUS $978. My read on this is that it's worth it; the business model is great. You do have to balance how much you want to be in the business of fixing crappy old washers and dryers...OR you just buy nice new ones and extend the expected life out to 10-15 years. Both projects make money but cheap appliances have lower vandalism/theft risk.
It all boils down to numbers and we're in this business to make money. If it makes enough money to pay you for your opportunity cost, pain, and profit, then do it. Your Internal Rate of Return (IRR) on this project is 31.9%; not bad!
