Two of us and a dog live next to Ajijic for about $1,750 a month plus car insurance and health insurance, so $1,500/month is very doable. Rents are higher during the high season (Nov to early May) so renting at other times is less expensive. Ajijic is generally more expensive than surrounding towns. As already said, Jocotepec is less expensive not just for rent but for just about everything. There are few expats who live there and only the easternmost end of the town is on the lake, though. Chapala, the first city on the lake from Guadalajara, has great lake views and a lot of expats. Rents there are generally less than around Ajijic and you are only about 5 minutes drive away. Renting short term to find a Mexican landlord with no realtor involved will save you a bundle over time, even in Ajijic and environs.
