We are planning to buy a resale Lennar home (built in 2008) in Behren's Ranch. Is anyone aware of any issues (foundation etc.) with Lennar homes in this area?

Also, the first floor of the house is stone. The backside of the house has stucco on the second floor and the inspector said that the stucco wall was missing "Weep Holes" to keep the moisture out. How big of a problem is this? We have been searching over the internet but haven't found any definitive answers.

Weep holes regulate moisture content in your wall cavity to prevent mold issues. Think of your exterior wall as a soda can on a warm day. The layers of your exterior wall (masonry/vapor barrier/sheathing/studs/insulation/drywall) will form condensation or "sweat" from the cooler temperatures inside during the summer - and outside during the winter. Weep holes allow evaporation of this condensation. If you have weep holes where the masonry meets the slab, then you should be okay. You don't need them on the second floor. I would be more concerned with whether the stucco has control joints - spaced 20 feet on-center usually, as you would with brick. This is why it's important to run your A/C even when you are out of town, you want to keep that "sweat line" outside the vapor barrier. Vapor barriers keep out the mositure, but it can accumulate inside a hose as well. This is why public schools in Texas had huge black mold issues a few years back - especially in South Texas. During summer break, the A/C was turned off, and the campuses being spore factories. I also would not run a humidifier for extended periods in your house during the summer either, or sweat could form on the interior side of the vapor barrier and form mold. Sorry for the tangent, but if you have weeps at the masonry where it meets the slab, you'll be okay.

The house has a stone wall above foundation (for the first floor) and above that (on the second floor) the back wall has stucco. There are weep holes where the stone wall meets the foundation. But none at the bottom of the stucco portion of the wall (where it meets the stone). Do you think this is a big issue?
