I am sure that you will find the weather here a large bonus...Your life style will most likely improve as the cost of living is reasonable... We are Ajijic returnees having lived here for four years and then returning to the US... We came back for the weather and a better life style... I would recommend spending a number of months here and check out the various communities... As mentioned above, Tom Barsanti is an excellent person to speak with buying a house or not...
You will find that things are a bit different here but if you are open minded, have a sense of humor, and not time driven, you will find it most wonderful place to live...
