Do you expect to live long past that time frame and be healthy enough to fully enjoy that great cash flow and deal with the landlord stresses?

Now, I can't pick for you, but consider what suits your budget and lifestyle better.

I've been able to get a healthy combination of both cashflow and appreciation from all my properties after a little TLC.

When I started I scaled back my lifestyle, sold stuff, and got debt free to fund my first rehab. 

Or changes in lifestyle? 

I've been able to get a healthy combination of both cashflow and appreciation from all my properties after a little TLC.

Im seeking some advice to motivate myself into making the jump into the investing lifestyle.  

It would only make sense to me if it’s a lifestyle decision and, even in that case, you could most likely find a much better deal.

Beware that 1) some lenders might not lend in Tulum because they deem it too risky given the oversupply situation and 2) other lenders won't lend if the purchase price is below $750k because you can't get title insurance in Tulum specifically.Finally, beware also that there's a huge difference between a lifestyle purchase and a (profitable) investment purchase, the latter being all about numbers.

Even with the possible down payment gap, it's imperative to thoroughly review the figures to make sure the investment is still financially healthy.
