Really depends on what you're looking for, the nature of the project and again, location. 

I also assume a 3-4% yearly rent increase, which naturally increases the vacancy and repair amounts over time.

@Mike Lambert I'm curious about the nature of your investments in Mexico, geo area, type of investment, etc?

I have not had that happen, but natural gas is a lot more reliable than power. 

You want to add value and reduce expenses.Also, it is wise to have a healthy liquid reserve available when buying commercial real estate.I would call commercial real estate brokers and find one with a teacher's heart.

I just checked and it has reservations through the summer already and I'm sure its occupancy rate is close to 90%. 

I have a similar perspective, as I am right on your heels with the same decision, so I'm naturally inspired. 

You could reach out to the folks at The Nature Conservancy and they could provide additional info if that route sounds appealing.  

The buyer would need to show solid financials also of course (good credit, experience operating rentals, proof of funds for down payment and adequate reserves to cover any unexpected cap ex).

Further, I had negotiated 12 months interest reserve; they cut that to 3 months.
