Its not yet passive because i choose to spend most of my time on it to make it better, but i bought a cleaning business 10 months ago. I recently took a consulting contract for some additional money for expansion and it does run by itself (in the capable hands of my biz manager), however there are more optimisations i wish to make to it. Its the hardest thing i've ever done, but its at a stage where if i wanted to, i could simply take any time i wanted off and all i'd need to do is spend 15 mins a week entering payroll.
I've written about it before, if you want to look through my history.
Start blogging about it, there's got to be a good handful of stories and advice in that throw-away "Its the hardest thing i've ever done". When you're at a 100-odd pages, make it an ebook for more passive income :)
Mind sharing what the cleaning company is? You appear to be in the UK, and I will soon be in the market for a cleaner.
I plan to launch another cleaning business, utilizing what I learned in my launch 3 months ago and write an e-book, and of course sell it for passive income. :)
I'm actually considering starting a cleaning business, and I'd love to get your perspective. I'm a full time software consultant, and I'm looking for a way to get some semi-passive income flowing. Anyway, if you have time, please reach out to me at sean.d.hi at gmail dot com.
