My wife offered to drive some over, but they found them by then.My wife responded to the new complaint and said that she wished our guest had mentioned any of this during their stay so we could have addressed these concerns.

Pull up the address on Zimas.LACity.Org and you can see on the left hand side under the "Housing" tab.

In reality, it seems to do almost nothing to alleviate the problem(s) the municipality is trying to address.

I think there are multiple ways to address the issue.  

In terms of opening a bank account, most of them will ask for a local address but a lot of the online banks may not verify it. 

When these lenders were investigated; addresses turned out to be phony, licenses when claimed false and virtualy 61 of them wanted up front fees in order to process the loan.

Right off the bat, there are foundation/framing issues that need to be addressed. 

What's the address?

From the return address of the mail I received to the the address listing of apps I use at work, Ohio caught my eye.

Short story is that after a "reset" about paying on time last month it's 5/19 and I have half the rent and just had to send a plumber out to address a tenant caused water issue and I'm done at this point.
