I have been to the Cayman Islands plenty of times, and love it, but I want to find somewhere else - a hidden gem maybe... that has yet to explode as a tourist destination, but close enough to a major town that airlines can fly into as I need to make it somewhat affordable and accessible to people who would like to rent it out.

It'll be like the airline industry sort of. 

He'll need to set the heads, run the lines, hook up the lines, ensure a vacuum, pressure test, and release refrigerant, perhaps even adding some.The contractor knows he's not making a ton of money, and even though his margins aren't there because you're supplying the units, he needs to factor in you calling him and expecting warranty service if something runs afoul.

Every investor has different criteria for what they are looking at and investing is not done in a vacuum. 

You'll also need storage space for cleaning supplies, change of linens and towels and small miscellaneous items like a first aid kit, extra batteries, flashlights, broom, vacuum, etc.

This is common practice of discount airlines.

They know everything about them and you will come in knowing next to nothing.cash-is he reporting cash/coins from self serve bays and vacuum.

But otherwise, a room just needs new sheets (we have extras ready to go) and towels, snacks, and then we quickly wipe and spray everything down, vacuum (doesn't always need it after every single stay) and we are out.

Year 1 cash flow matters (don't buy a cash vacuum), but price appreciation and rent appreciation is how you get real economic security and build wealth.

If their CF was $10k a year, then it would take them 10 years to recover their cost...and then start making a profit.So you are saying that when United airlines buys a 300M dollar aircraft, they only make a profit when profit on that plane alone exceeds 300M?
