If you are following the letter of the law....if you own a place here that you are going to use as income producing property you are supposed to have a Mexican bank account and pay the 16% IVA to Hacienda usually on a monthly basis. Properly done your RE sales person can help you establish all of this. The condos since they are governed by an operator usually mandate that this is all set up. If you buy a stand alone house this small detail could be overlooked. There are more than a few homeowners renting their houses and because they are doing it through the internet AirBnB etc...they are probably not collecting and paying the IVA on income and that could be a problem for them in the future. Its not hard to set it up legally.
