A little help?

Elderly Mexican couple (my in-laws) searching for a house to rent. They require 3+ bedrooms and a fenced yard for their small pets (dog & cat). They are being forced to leave their home by May. Their income is very limited because they are 80 & 84 years of age. They are devoted church members (protestant) and prefer to remain in their Chapala-area, but is not necessary. Please respond if anyone knows of a possible rental....the rental needs to be for a permanent arrangement. They are a very gracious and low-key family! Thank you!
