200% Cash On Cash Return!!?? Time To Go All In!

[Dominic Balconi]

Please tell me what you think about the validity of my deal. 

I just calculated the cap rate for a property I'm going to develop within the next year: 20%

Here are the numbers:

$40,000 to build

$30,000 for the land

2 Units

Annual Gross Income: $24,000

NOI: $14,000 (conservative estimate as expenses will be low, as property will be brand new)

DCR: NA (all cash, no loan)

Cash on Cash ROI: 200%+

These numbers seem unrealistically fantastic. Am I to be worried that I'm miscalculating something somewhere? The property is also beachfront, so insane appreciation is to be expected, but is not a factor in the calculations.

If anyone is astronomically confused, the property is on the coast of Ecuador, South America, not the US! No need for comments about how this isn't possible; those numbers are real. 

Thanks for your input!
