Agents are paid one month's rent by the owner when a one year lease is signed and that is split with the real estate company. There is little money to be made by agents handling rentals, especially low end rentals, which is why most of the agency rentals are mid to upper price homes. It is not because the prices are higher than for a similar home not using an agency. If that was true rental agencies would not exist. If you are looking for a low end home where you will be expected to take care of most maintenance and repair issues then finding a Mexican landlord is the way to go. Of course, there may be some exceptions if you have the time, patience, knowledge and ability to find them.
