Yes end of discussion unless your Habitat for humans or some other charity this is financial suicide in my mind and you will destroy your family

My wife and I found out AFTER purchasing our own home that a few years earlier, the deceased husband of the widow who owned it had committed suicide in...shot himself...

So while on the surface yes every property in its own llc would be super independent, the moment you commingle the money a bridge was built from that llc island to every other llc island that also utilizes that bank account, and all assets, including all personal if one is suicidal enough to commingle personal and business funds.So, to recap, commingling is to asset protection what shaving with a chainsaw is to health improvement. 

@Sean S.For me, not working with an attorney on a multi-member LLC basically amounts to legal suicide.

Financial suicide by a 1000 cuts.. 

I had a Tenant commit suicide last month with a fentanyl overdose.

I call this financial socio pathic behavior at the end of the day they sell this stuff buyers get hammered and they make their fees live their great lives make on like this is something that is going to create financial freedom.. when real estate done right can do that.. real estate for mom and pops and few homes at a time in the hood is a recipe for financial suicide. 

or would you have to go out afterward and commit suicide once you discover just how badly you've been behaving?

A veteran commits suicide about every 22 minutes in the US. 

Note that I said single-member LLC --- for multi-member LLC, it's akin to legal suicide.
