Tulum, Puerto Vallarta, or . . . Someplace Else?

[Paul Primrose]

Hi. I'm Paul, and I just signed up for Biggerpockets because after years of living frugally and working hard (and a sizable bit of luck), my wife and I are able to seriously consider investing in (read: buy with cash) a winter getaway / retirement spot. I'm trying to head into the process with my eyes wide open, and yet . . . it snowed here today, we're both working from home, and I've been distracted by internet real estate sites and pretty, pretty condo listings. 

We both want to continue working our jobs -- me for 5 years or so, she for another 10 at least. We've done some research and really think Mexico will be the place due to travel time and costs. We'd like to rent (and hopefully cover mgmt. costs and obviously even profit) when we're not using it, which would be 15 - 20 days out of the year, max, until retirement happens. 

I'd love to hear pros and cons of Mexico destinations, particularly Tulum and Puerto Vallarta, or any other suggestions. We don't need something right on the beach, but close enough to hike or bike to the beach would be cool (hey Tulum!), and walking or biking to a local food market will be important. Bangin' nightlife and Instagram types are low on our priority list (there goes Tulum!). We're both outdoorsy and avid cyclists, and we have two kiddos in grade school. Our budget is higher than what someone might expect, but I'd rather not disclose those specifics here. 

Thanks in advance for your advice and insight.
