Zoom forward 2 months - I routed the bathroom fan properly to the exterior (fixing the humidity issue).

You've got mostly mild climate but a bit on the humid side. 

With half of this stuff what really matters is the prep and letting it adapt to the humidity, etc.

Too much heat & humidity = mold.  

Once that's done, modules start rolling in on flat-bed trucks, are lifted into place with a crane and the house can be under roof in less than a week.The construction of the modules does occur in a sheltered environment without precipitation, sun, wind, high humidity or wide temperature swings.

The best months to visit are January through to April, as they are the driest and least humid, and usually a couple of degrees Centigrade cooler than other times of year.

Not specific to your unit but in general it is normal for water to be in the tray of your unit, especially in a high humidity region.  

There is definitely a balance, I would be more inclined on construction quality/non-AC central system/non-insulation (due to humidity), and the typical Caribbean pi~a colada! 

,i'm only saying what i saw on other student housing threads:-concrete/block walls (deters punch-ins)-house built at an angle from the street (bottles impact)-plywood behind the drywall (deters punch-ins)-double sheets of fire-proof 5/8 drywall (deters punch-ins) + happy fire-marshall-everything hosable-bathrooms with fans on timer/humidity separate control-toilets/faucets from plumbing supply with metal internals in a major manufacturer (moen/delta/american standard)-LED fixtures hardwired (no bulbs walking away....)

They were also blocking the hvac vent in the basement because it was cold, but that would raise the humidity - and they understood that as well.
