Infonavit has a portfolio of several thousands of mortgage foreclosed properties. These properties concentrate disproportionately in several municipalities, so the way and the time Infonavit chooses to dispose of them will have a considerable effect on these communities. Beyond the specific approach Infonavit takes on placing its foreclosed properties back on the market, the only monitoring these dwellings receive centers around the legal procedures needed to claim the collateral. No further analysis is performed on this portfolio and the spatial dimension of the issue is hardly being considered. At the moment, Infonavit is unable to locate with reliable precision its foreclosed dwellings.
