I'd suggest avoiding it. They pay will be low. The management company will likely treat you poorly. If you're going to do commercial work like that, I think you should be compensated well. There's a higher likelihood of damaging something at a Walgreens than at a typical residential property. By that I mean, more cars, pedestrians, etc. Damage one car or hit one pedestrian with a stone and there goes a season or more of your profit. If you proceed, do so with extreme caution!
