Also, the number of collections for your ROI will vary depending on how fast you upgrade. eg: Build a Hot Dog stand, as soon as it's built, upgrade to L1, as soon as it's upgraded, upgrade up to L5. Then the first every subsequent collection will be $70. So add up the construction cost and 5 upgrade costs and divide it by $70 and take into account the repair rate to get the minimum number of collections required. I think that will be the only meaningful number. You could work it out for each level on the basis of upgrading to that level immediately.

When we have the minimum collection ROI numbers, it is up to each individual to take into account the time for each green collection, construction and upgrade times, and our mode of play, to best-guess our ROI real-life time. eg: logging in once a day for 2 mins, ROI on a L5 Cabin will be forever. But playing for 2 hours straight twice a day, it will be returned rather quickly. Whereas the ROI time for a Golf Club or Magnate Hotel will be about the same for either mode of play.
