These vacation rentals would also be available on a long term basis, you should contact them all and see what kind of a rate you can negotiate by being willing to offer long term occupancy. You could also contact some realtors to see if they know of anything for rent, here is a list: http://yucatantoday.com/en/topics/yucatan-real-estate Also check out yolisto.com where lots of expats exchange info and someone may know of a house to rent. Good luck!
