(cinematic)
I was chatting with the owner of a house in Playas. The house rents for 400.00 per month. To lease the house I had two options.
(A) co-signer (Mexican citizen that owns a business or property in Mexico) plus first and last months rent. Total $800.00
(

no co-singer. Move in fees were 3 months rent (as security deposit), plus one months rent. Total $1600.00
Is this standard?
Three months rent for the deposit is too much money to put down. Sounds to me like this person renting the house might be planning on pocketing some of the deposit when you move out.
If you don't have a fiador to guarantee the lease then most rental companies here in playas will ask for 2 months rent as a deposit. I don't have a fiador as well, so for 2 of the 3 houses that I've rented here I had to put down double the normal deposit. Also, if another party is renting the house or apartment for the owner you will have to pay a commission fee to the third party. Normally the commission is half of one months rent.
