My stepdad owned a few rental properties when he and my mother first met, so I was exposed to some variety.

Electrical; illegal and exposed wiring on exterior, knob & tube wiring in the attic, galvanized plumbing, old roof and mold in the one tenant occupied unit.

These can be cracks in the walls/ceilings, exposed openings under the slab, Windows and doors sticking, etc. but overall, we look at the signs and form an OPINION of what we think the foundation is doing at the time.I personally use a method that takes a lot of the guess work out but I'll get to that later.One of the EASIEST signs of a failing foundation is the separation of the frieze boards on the corners of the home.

The master has exposed beams with a vaulted ceiling and it has a balcony off the master bathroom.

This is EXACTLY the sort of conduct that will convince a court that you disregarded the legal separateness of the LLC so that the corporate protection should be waived and your personal assets exposed to recovery by the plaintiff!!!!

I find that cross-listing them on Furnished Finder and Airbnb does a great job of exposing my listing to a variety of potential tenants for maximum occupancy.

That is great that you met some mentors at a local REIA to get exposed to that interesting niche.

The members of an LLC are issued a K-1 Form and have to pay taxes on all profits as though it were income, which could expose the owners to high employment taxes.

You should learn how courts have 'pierced the veil' of an LLC and exposed owners personally so that you can avoid those types of mistakes.

Too much ego/ pride to come on BP forms and expose their foolishness.
