To my knowledge, there are no city ordinances prohibiting domesticated animals but you can always contact the City.

.: I don't charge deposits for animals because deposits are fully refundable.

When speaking of a strictly commercial loan that is a different animal as is not 2 units purchase first time buyer which @Thomas Lebens states he is. 

Let me steer you in the right direction.Imagine you buy a list with the address of vegans, that are also animal rights activists.Your company sells baby-cow burgers.

It also sits on 2 acres with separate buildings for animals and a nice storage shed.

Multifamily (5+ units) is a different animal than SFR, but there agents (or brokers, as they uniformly call themselves) clearly add value, in my opinion.

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.

The tenant is responsible for the animals and what they bring in, not you. 

Now, buying at auction is a whole different animal since they are typically sight unseen.

I think if people were a little more aware of/ comfortable with the fact that these human psychological booby traps not only exist, but are very easy to fall into even for the educated/experienced/professionals - it's how we're wired as animals - maybe fewer investors would get taken for these rides.
