I am currently house hacking my primary residence in California and just bought a rental property in Indiana. 

From talking to locals, there's a couple of issues than need to be addressed, some are the non-ecological practices that some of those developers have, unfortunately, our government profits from this investors and allows them to destroy manglers (which are the natural water purifying system of that area) dismantling hectares of mangroves and degraded the habitat of resident and migratory species burying animals alive.There's proof of fecal material floating beneath the city of Tulum, only 20% of the water is sent to the water treatment plant, there's no infrastructure for the exponential growth.The landfills in the middle of the jungle that is leaking hazardous pollutants into the freshwater system and that something that developers won't tell you.I love my country and it would be a disaster for everybody if this place ends up like some other great beaches around the world, that are completely ruined by greedy investors not following the rules.There's no urban or comprehensive master plan, and one of the risks is that Tulum will be like Playa del Carmen is today, overgrown and with environmental devastation.I will advise doing a lot of research before getting something in Tulum, different country, different rules, and practices.

AND you’ll need to be living in the home as your primary residence WHILE it’s rented out. 

Never had a problem with mine at my personal residence then again I'm sure tenants run it hard. 

Quote from @Donald Hatter: Pros:- Builders have many homes to sell at one time so it is easier to negotiate a better deal than with a home owner in the same neighborhood who is trying to sell their primary residence - Buyers bust out of deals all the time and builders don't like holding completed homes- Lower maintenance which leads to easier property management expenses.

@Mary Lopez I'm also a California resident investing the mid west. 

And why is it that every single home - whether its a rental cabin or primary residence - doesn't have to have a sprinkler system?

There are companies that buy properties, renovate them, place a resident in the home, sell to an investor then property manage for the investor as well on the back end.
