I recently watched a BiggerPockets podcast on YouTube where both folks made flood insurance mistakes from not noticing something in the disclosure.

If you have a 6 bedroom in an area that does not have a university (students looking for shared space) or is in a family friendly place it may sit vacant longer between tenants.For Capex, try not to use a generic number - look at the roof, furnace, hot water tank, kitchen - when will each need to be done and what will it cost?

The problem is the waters are muddied when a negative occurs with the investment that is in no way the result of dishonesty or incompetence; it’s merely the revealing of the probability of an outcome that has been properly disclosed as a possibility - yet the unsophisticated investor begins crying Ponzi scheme, theft, incompetence and every other accusation they can think of rather than considering the possibility that they made an investor with higher risk than a money market fund. 

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.

If it is, I would do whatever I could to get good paying tenants in there right away,  If it is vacant, you are going to be running through cash like water through a sieve. 

That certificate would show open taxes, water, housing violations, citations, condemnations, receiverships, construction liens and other municipal liens.

Given this is where my major operating expenses fell (beyond taxes and insurance), keeping this cost lower, by average, helps my cash flow.I invest in older neighborhoods, so the 2-4 unit properties, typically have single water meter, maybe single electric, and many have radiator heat with a single boiler.  

I assume it has sewer/septic, water and electric and they 2 tiny homes are plumbed/wired?

A 2 bedroom in town verse a 2 bedroom that overlooks water are completely different things.
