Am I an actual business that needs to do things more formally at this point?

Hi there,  after reading a few posts and going thru one of the books Brandon wrote - I realized that I might be able to find a much better deal by just heading north of the border of IL to WI.   

-We have heard that we are super "extra" since we rent by the room and people aren't use to being so formal with room rentals, but we have established the rules and formality from day one.

Some useful info here:https://www.opploans.com/oppu/articles/8-money-pitfalls-to-avoid-when-co-signing-a-lease/Pitfall No. 7: Not putting all roommates on the leaseFalen Cox, attorney at Cox, Rodman, & Middleton, LLCReaders should be aware that if they allow another person to live with them, even without the intent to acquire a roommate or create a landlord-tenant relationship, they may have to go through the formal eviction process if that person refuses to leave.”

I also plan to open up the one bedroom at the landing of the stairs to create a formal “landing” area.

I didn’t make any formal complaint or anything but i was annoyed

My current plan is to let her know my intentions in a conversation and let her know a formal written notice will be issued by end of the month.Another concern i have is how to deliver written notice, is it as simple as handing a letter to them, or do i need prrof of it somehow, i.e. have them sign something having received the notice.

This took a formal complaint to a VP to address a simple issue. 

No, most HMLs don't do a formal appraisal on the up front side, they simply rely on their own analysis and price opinion to underwrite the loan. 

(or call you so they can demo next time it happens if they can't make it happen on demand)3) Adjust place as needed for legitimate placement issues.4) If failure to keep smoke detectors working is a breech of your lease then do a formal notice to cure as required by your state just to have it on record.
