permits are not often pulled for a lot of what he is talking about.. subs are not required to be licensed that's a huge problem Also building codes in TExas are weak  one really needs to be aware of what your buying there.. next thing will be soil and foundation issues.

For example, we had a client that's home was on a ton of clay and during a drought the home literally split in half because the soil shrank and no insurance would cover it so the bank of course foreclosed. 

If cold air eventually works it's way in through the exterior siding due to wear and tear, you will start to have issues like drafts coming out of outlet covers, from underneath baseboards, and from behind window trim/molding.

Bring a hose and run the water outside the bathroom soaking the soil.

Of course it is not fail proof, but for instance, if I have just one company with everything underneath it, then it can easily be sued for everything.

I invest in Toledo Ohio, Just beware of Expansive soil.  1/2 the houses that folks want to sell to us have foundation issues and they will tell you "now issues with foundation".  

But, in the Denver market I study/invest, I can show you examples where the land underneath is appreciating like crazy and the neglected 100 year old or 50 year old house is worth zero.

Soils near swampland are often nonhomogeneous and mixed with organic matter which decomposes over time.

It is the opinion in Texas that you must treat a Series LLC and the Series underneath it as if they were separate LLC's.

I own 4 units in 100 unit building...there is a garage underneath..potential for carbon monoxide problem ...as far as upkeep and repairs ..
