Getting mattresses, couches and other large items picked up is expensive.If you caulked holes from the tv installation, it sounds like the patches were done incorrectly and will need to be redone.

It seems they want to be fully protected if by some wild series of events they ended up owning the property.

I would have lessons with his daughter after school, while he would be in the next room of their very nice home drinking, watching sports, and throwing things at the TV.

Point is, if I were to purchase the property, legal as it may be, that leaves me the buyer with a large problem on my hands (not to mention all the clutter that was apparent (old frig, busted up TV, two wrecked cars, etc.). 

I currently use a Texas series LLC for my TX houses, and I use a FL LLC for my Florida houses; I also have an S-Corp which manages the two LLCs.

I have heard of setting up a series LLC.

We were thinking of adding an accent wall on the wall our TV hangs on, but we weren't sure if that would even matter on selling the house? 

Assuming I had the experience, I would only buy a place with structural issues if I had 1) an experienced and trusted structural engineer telling me a clear, and verifiable explanation of the cause(s) of the problem and a viable and affordable solution, 2) trusted and experienced tradespeople who would be implementing the solution (carpenter, mason, etc.) confirming with me that they could fix the issue (with 90% or higher confidence that the issue could be resolved within budget), and 3) confirmation from city inspectors that the issue (and an inability to fix the issue) would not result in condemnation/revocation of occupancy permits. ...and even then, I'd only proceed if I had the cash reserves to ride out a major series of unexpected problems (e.g.; time overruns, budget overruns, unexpected revocation of occupancy permits from the city, etc.) 

I have a series LLC for my rental properties in Utah, but I am not sure how effective it would be for holding a property out of state.2 - I do subject to deals in Utah using a General Warranty deed.

I had a great series of interactions with a local financial planner but several months into our relationship he admitted he was just too busy to get to me for at least another 6 months.
