Some investors will continue to earn a healthy return on their investments while other will not be able to survive.

I'm sure that, as @Bruno Demarco Quiroz mentioned, you'll be the first to agree that getting a double-digit return today or in the future will likely be the exception rather than the rule, at least until the municipality stops giving building permits to anyone and their mother like and decide to reign in supply like they've done in other parts of Mexico like Cabo for example.Not long ago, I met with a real estate agent on the ground who mentioned that, given the changing market, Tulum had become a lifestyle market rather than an investment market.

I didn't need cashflow to survive on, just as it appears that you have a healthy career outside of real estate.

The city's diverse neighborhoods cater to various budgets and lifestyles, enhancing its appeal to a broad tenant base.

I prefer a well manicured Green properties as we attract long term Tenants with well maintained landscaping in California people who consider lifestyle will pay higher rents.. 

Look for properties that offer good rental potential and fit your lifestyle. 

Create a community about how you will change their life or lifestyle.As someone once told me:in absence of a product, an idea will usually be sold; when the idea is lacking, a lifestyle is pushed.

If your goal is to become financially free and ultimately leave your W2, the $850k home and the accompanying lifestyle is going to be your biggest obstacle.

I took me 10 years to build up the consistent cashflow that I needed to live the lifestyle I wanted and quit my day job as an engineer.

The reason this is very dangerous is because not only does it impact your cash flow, but it also impacts your ability to exit as pricing is typically based off of the NOI approach.2) Natural Appreciation: Currently there is some healthy appreciation in the market, however, is that going to continue at today's rate for the next three years?
