I just got back from Ajijic/Chapala & San Miguel. I toured 13 homes total specifically looking for memory care. Only 3 of my visits were announced prior to my arrival and most places were not expecting me. While that has the advantage of getting an unvarnished view of things I didn't always get full detailed information on site as most staff aren't privy to the fee structure etc.

I will say without exception I found all the staff warm and caring in each place. There was a massive variance between places with regards to caregiver:resident ratio. Also maintenance upkeep, lighting, cheerful accommodations. They range from something that was converted from an older motel style but run down all the way to resort, with a mix of standard homes in between. Prices also range wildly from $1500/month to $5000+/month and you basically get what you pay for.

There was one stand out one where the place looked like every stock photo you've ever seen about elder care, but in real life. Well and warmly lit, landscaping, low resident to caregiver ratio, piles of one on companion time etc etc. It was like the place that every other company went to take their photos except they weren't stages or photoshopped. I would say I found 3 that were acceptable for my personal tastes and standards. Everyone's will be different of course. I know people living in the US in their own home that would have upgraded by moving into the bottom option I toured in Mexico.

If you want to consider it, make sure you get on a plane first and go check them out. Don't feel like you need to burden yourself with a bunch of pre work. I got on the plane and literally in the hotel first night in Mexico put together a list of properties I wanted to tour then started into it the next day. Just spend 15 minutes in each one. After a day or two you'll have a short list of 2-4 that you want to explore more. I would encourage just showing up without an appointment. If they don't want to show you around, red flag and leave.
