After heavy rainfalls you will have a problem to enter that area. It starts on the corner where the "NUEVA VIDA" tent is (church/School)
On the other side: that happens maybe 1-2 times per year. If the price is ok, you construct the house a little bit higher... and get a real 4x4 high enough, no problem. Think about security! Hotel Voramar has their own, some houses have problems!
