How To Calculate True ROI in Mob Wars?

This is regards to the Mob Wars game on Facebook, specifically the 'City' mechanic. It seems to be assumed that there is no benefit in investing in 'land' vs. 'buildings'. I want to know if that is valid.

For those unfamiliar, it works like this:
First you can buy any of five types of land (listed here with initial price, and income provided):
Empty Lot :: $5K :: $0.1K
City Block :: $50K :: $0.3K
Downtown Square :: $1M :: $2K
Beach Front :: $4M :: $8K
Container Yard :: $6M :: $12K
The income per unit of land is static. As noted, the price is an initial price. The price charged for a given transaction is P=I + ( n * 0.1I )
Where P is the actual price per unit for a transaction, I is the initial price, and n is the number of units owned at the beginning of the transaction.
Additionally, you can buy land (and buildings) as units, or in groups of 5 or 10. Since each transaction increases the cost of the next transaction, it is ALWAYS more efficient to buy in groups of 10.
Example: You own 700 Empty Lots. Your income from this land is $70K. The next group of 10 will cost $355K each, for a total cost of $3.55M
Next buildings. The mechanic for buildings is almost exactly the same, with one change: Any given building will 'consume' a land. For example, Villas consume Empty Lots, so you must already have 10 Empty Lots to purchase 10 Villas. This almost means that the price you paid for that land is effectively added to the price of the building.
Because income per land/building is static while cost goes up, the return on investment (ROI) decreases as you purchase more units. All other things being equal, it would be efficient to purchase from all land types and building types to keep ROI as high as possible for each purpose.
However, as noted above, land cost adds to building cost, decreasing the ROI of the building cost more than just the normal cost increase.
So: The actual question. Is it ever effective to invest in land, or will the hit to building ROI /always/ counteract the income from land.
For reference, the details on buildings are below
Building :: Initial Price :: Income :: Land Used
Villa :: $10K :: $.3K :: Empty Lot
Restaurant :: $30K :: $.7K :: Empty Lot
Apartment :: $200K :: $5K :: City Block
Hotel :: $400K :: $10K :: City Block
Highrise Apartment :: $5,000,000 $50K :: City Block
Office :: $16M :: $150K :: Downtown Square
Luxury Hotel :: $20M :: $200K :: Downtown Square
Beachfront Hotel :: $30M :: $220K :: Beach Front
Casino :: $40M :: $300K :: Downtown Square
If there are any additional questions, I will answer them the the best of my ability. If the answer varies based on amounts of this or that, I will be happy to have a formula that describes a true ROI for land.
