Sign on the dotted line, and you will hate yourself in the morning...
This company Dadson Washer Service will sucker you into signing in 30 year plus lease. Ten years with many AUTOMATIC renewals, that only THEY can cancel. In addition, READ THE FINE PRINT IN THE BACK OF THE CONTRACT they will have the right to increase their "take" every year until you get NOTHING, NADA, ZIP. They will own your ass!
They are not breaking the law, and make it so you agree to give them your money. Their lawyers have fine tuned their "standard" (or screw you lease which is a lopsided as a camel with a freight train on it) so it holds up the best possible way in court.
And keep in mind, that you have to assume that they are in fact giving you your share of the laundry income which even if they do you are still screwed. That's a big assumption with this outfit. A much safer way, is collect the money yourself by either leasing the machines at a fixed monthly rate (around $25.00 a month per machine) from a REPUTABLE company, or finance them to buy them outright. It's a bit of a pain to collect it yourself, but you will make a lot more money.
