If you did not send it certified mail you may need proof of when you gave notice. 

@Bryan JuI don’t allow my lease to be signed until I have first/last/security deposit in certified funds (not online) and utilities switched.

The property might not see natural appreciation over time, but you could always force appreciation with a renovation.

My plan is to buy and hold.PUB02121 of the MO Department of Natural Resources states that “demolition or renovation to an institutional, commercial, public, industrial or residential structure (excluding exempt residential structures as described in the preceding section) will involve greater than 160 square feet, 260 linear feet, or 35 cubic feet of regulated asbestos containing materials, then the removal of the asbestos is regulated by the department” but the City Planning and Development Guidelines for KC state “any person undertaking the demolition or renovation of any structure shall employ Missouri registered contractors and certified workers”.It seems to me that the city regulation requires you to contract a certified asbestos abatement professional while the DNR will only require this action when meeting a certain threshold of asbestos material but I am not sure.I should add that I am not an experienced real estate investor nor do I work in the real estate industry but I want to go into this with my eyes open and I am sure I will have many more questions in the future.

Appreciation, both forced (rehab) and natural (market, time)4.)

I'm guessing lots of landlords would be happy to upload these, and once a bunch are uploaded, the computer generated ones with copy-pasted identical signatures would start to stand out.Possibly.If your number rings straight to the "ESA Mill" then more than likely you will get no where.If you end up reaching the actual doctor named in the certified letter, most likely that doctor has some sort of arrangements with the ESA certification company to use his/her name in that capacity. 

I've seen people mention looking at employment rates and projected employment rates, population growth/decline and things of that nature.

I notified the tenant that I would no longer be utilizing his services and started the eviction process giving him 30 days to move out (used a legal process server and also mailed certified letter).There is no written lease at all, and tenant has lived in building for approximately 10 years.

Typically more simple in nature because often it's only 1 person operating the software. 

Then it has usually been 30-45 days before you get notified that the process is complete and you go to the Sheriff's Office and pay the balance with a certified check in the lobby of the Butler County jail, lol.
