ok, this article proved to be a little more challenging them others I’ve done of this type. To start with. These are the full stats of each of the buildings

So, you’re probably wondering which one makes you the most money. Unfortunately, the answer to that question isn’t simple.
If we assume that the only constraint is space then the formula is
Profit per Square day = $ Profit x (24/Time) 
This is essentially then the same as it is for other farm sim type games. However, you can purchase land pretty easily and each purchased plot is fairly large. This means that space isn’t really limited and that for the most part you are only limited by your money. This means you would buy some buildings and then use the profit you get from those buildings to expand further.
This can be calculated recursivley using the formula
Total Profit = # Buildings x (Profit/Purchase Cost) 
Of course the Total Profit value you get represents how much money you make at “collection time”. If we assume that all of this money is reinvested by purchasing more of the same building. We get the following set of equations.
IC = Initial Cash
R = Profit Rate Cost = Building Cost Profit = Money generated at collection Price = Building price 
Profit = (IC/Cost) x Profit 
Now, if we take the Profit Rate to be
R = Profit/Cost 
therefore the first three cycles can be expressed as
Cycle 1 (P1)
Profit = IC x R 
Cycle 2 (P2)
Profit = IC x R + P1 x R 
Cycle 3 (P3)
Profit = IC x R + P1 x R + P2 x R 
If we make the proper substitutions and expand Cycles 2 and 3 we get the
following
Cycle 2
Profit = IC x R + IC x R^2 
Cycle 3
Profit = IC x R + IC x R^2 + (IC x R + IC x R^2) x R
Profit = IC x R + IC x R^2 + (IC x R^2 + IC x R^3) Profit = IC x R + 2 x IC x R^2 + IC x R^3 
Now, since each of these terms contians ICxR we can pull this term out to the side, this gives us
Cycle 2
Profit = IC x R x (1 + R) 
Cycle 3
Profit = IC x R x (1 +2R +R^2)
Profit = IC x R x (1+R)^2 
Using the above method I can expand out cycles 4 and 5, resulting in
Cycle 4
Profit = IC x R x (1+R)^3 
Cycle 5
Profit = IC x R x (1+R)^4 
therefore if we take T = Cycle number we get the following closed form equation
Cycle T
Profit = IC x R x (1+R)^(T1) 
This equation represents how much money would make after T cycles assuming that you reinvest all of the money you make at each cycle into purchasing more of the same building. Using this we can get the following table. The values below are calculated assuming an inviital investment of $15,000 since this is the minimum amount required to purchase the most expensive building

As you can see, something like the spanish home is great for expansion purposes but it’s low on the profit rate per day. Conversely the Corprate tower is awesome in terms of profit output but it’s terrible
in terms of expansion. So ideally, you would use a high expansion building to intiially build up your cash until you’ve maxed out your. Then afterwards you can go back and replace those buildings with ones that generate large amounts of income for the space they take up.
Of course you also need to consider how often you can collect from each building as this can end up limiting your options.
