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. 

If I could go back and start over this is what I would do as I did not go to college and learned it all the hard way which took me a lot longer and cost 10 times what a formal education would have cost.

The answer to your question here is going to be based on what the 4% rule is more formally known as: "The Safe Withdrawal Rate" or other similar names including the word "safe." 

Do you have any formal negotiation training?

We (two partners and I) are thinking of doing the same things, and we also have our SOLO401Ks with @Dmitriy Fomichenko.Can anyone chime is as to whether or not an 3 way LLC's 'buy sell agreement' that sets a price at a 'multiple of rental income' (example is 100 x monthly rental income = purchase price.... which happens to be VERY close to the tax assessed value) can be used for valuation purposes instead of a formal appraisal?
