Check Craigslist or Renter's Warehouse if you are looking at buying rentals.

If you want to check, maybe buy a couple of daylight and a couple of 2700 K ones at the store, and try them out at your house.This rating (the color temperature) is not always on the front of the LED lamp box. 

The fourplex that I am looking at does not have electrical conditioning system, but instead evaporative coolers on all 4 units.I have not experience with this cooling system.Is it possible to bring the temperature below 80F when the outside is above 110F?

I would stay away from Renters' Warehouse. 

There's no exact science to it but like you said it's only usable about half the year (due to temperature, I presume) and then even when the weather is warm, it could be raining, so truly only available likely somewhat less than half the year - maybe an extra $0.15 - $0.20 psf/mo added to the $1 psf/mo sounds reasonable.

Warehouse jobs are $18 per hour. 180 price reductions in the last 14 days of 868 listings or 20% of listings.

I told him about how high my electric bills were at my warehouse where I use a portable AC for the office.

Heraklion Has a little more warehouse available as it's the 4th bigger city in my country.We have some phase 1 areas in my country but I cannot step in as I am a novice investor and didn't even bought my first property/apartment.

A friend of mine who is selling on Amazon, needs a warehouse because his business is growing.

The progress I've seen to date has bee positive (Costco, luxury apartment builds, bike share, park improvements) and the progress announced has been exciting (ferry, additional luxury complexes, trolly, commercial development for higher streets, warehouse jobs, connected parks).
