I only did a handful of houses last year, but plan to do (hopefully) a dozen to two dozen homes this year in nicer areas. I don't want to go into a bunch of detail if no one cares. But, if you are willing to spend $100 on a ladder and have a flexible time schedule then putting up lights can be well worth it. Just to give you an idea, I charged about $150 to do a second story roofline and both putting them up and taking them down amounted to about 3 to 3.5 hours. So, if you can do a few houses, you could pay for your season pass! If you want to do it honestly, let me know and I can post more ideas about how to market it.
