Lack of economic profitability in many commercial buildings

[amir77a]

We are all buying commercial buildings in order to... gain coins.

I've investigated little economic profitability calculations in many commercial buildings and found that many commercial buildings are just doesn't worth the investment.

Some examples:
Business center. Costs 1,200,000 coins, earns 240 coins per 8 hours. In 1 day, and only if we will collect the coins every 8 hours sharp, we can earn 720 coins per day. That means ROI of 1,666 days or about 4.5 years. So, only after 4.5 years, you really start to earn.
High rise hotel. Costs 610,000 coins, earn 66 coins per 20 minutes. In 1 day, and only if we will collect the coins every 20 minutes (and really... no one can do that) sharp, we can earn 4,752 coins per day. That means ROI of 128 days or about 4.5 months.
Courthouse - Costs 825,000 coins, earns 720 coins per 2 days. That means ROI of 2,292 days or about 6.3 years. So, only after 6.3 years, you really start to earn.

So... Why shouldn't we just keep our coins to ourselves?

Excellent analysis. My gut told me these high cost buildings would never pay out but I didn't do the calculations. Thanks.

Helpful.

Because of the items they drop and never because of the coins they return.

Business Centres - 33 mystery bonuses still to collect....

And when you have more coins than you know what to do with, why not?

Don't forget about booster buildings that will make the profit bigger and also side missions that require to build some buildings.

Invest in the airport facilities? upgrades?

Just invest it to get it back after a long while...

That could be a point...

Because they look pretty . Or it’s a side quest?

These are reasons I can understand, but I refer to the economic side of it.
I would expect a much better ROI.

The ROI is in the collections that the buildings drop.

Which of these buildings drop items and Etsy collections are associated with them?

Edit:
Just managed to find the following.
Private School - Cards On The Table
Courthouse - More Precious Than Gold
Business Centre - Liquid Assets.
Basically they give mystery bonuses.
