In my county, we had to file an actual paper request with the caseworker every year for each unit. 

The property owners IN MASS burnt down their properties, which, since they did not file insurance claims was actually the only LEGAL way to free themselves of the continuing negative cash flow of these buildings.  

But it can take months for them to file the paperwork and do it and that is what we eventually get back paid for in a lump sum.

You are going to be thousands in the whole before you ever start and any cashflow you get from a rental will be eaten up in tax and corporate filings.

Every state has a dept of corporations where their info should be filed.

In CHS, the county assessor has a two page form that you complete and file with the assessor's office, similar to applying for the legal residence exemption. 

Fair Return:An owner can also file a petition for a rent increase based onfair return.

I definitely would want the mail to go to the correct place.If someone wanted to sue you, the fact that you ignored changing your address would be a good argument that you are not maintaining corporate formalities, potentially having the protections of your LLC ignored.Most states have annual filing requirements for the LLCs so that would be a good time to update it.  

The Spokane market has been very good to me here and my contracting business focuses on mid-high end remodels and ADU conversions.

Full disclosure, I recently started coaching rehab for them since I have 20 years experience in remodel and design.
