Nice to meet you! I've never been to Puerto Rico. How long have you been there? Spanish will come easy if you just practice a little everyday. I was fortunate enough to learn some from family...I'm half Colombian. Mexico is definitely very affordable if you are earning dollars. I was when I first moved, but have transitioned to working freelance, so I miss the dollar lol. But also the cost of living is very low in most parts...Mexico City being the exception depending on what neighborhood you want to live in. There is a very high influx of foreigners/immigrants living in the central zone, causing rent prices to go up quite a bit each year. It's actually cheaper to live in Playa del Carmen or Tulum...but not so much to do work-wise, unless you sell crap to tourists haha. You will love it. I was say try to see plenty of cenotes (sinkholes), they are pretty impressive. Lago Bacalar is also a beauty to see due to all the colors in the water. I definitely prefer Tulum to Cancun or Playa, but the party is good in Playa if that is your thing. Cheers, hope I was helpful!!
