In the past I've used these envelopes for sending out my Yellow Letters but they are quite more expensive. 

So this loan would have a balloon.  

Corporate letterhead on fancy paper or standard yellow letter and chicken scratch?

For example, if you are seeking a reasonable accommodation for an emotional support animal, you may be required to provide documentation from a physician, psychiatrist, social worker, or other mental health professional that the animal provides support that alleviates at least one of your disability symptoms or effects of the existing disability.If your landlord or manager asks for this verification, you should obtain a signed letter from your doctor or other medical professional, or other qualified third party who, in their professional capacity, has knowledge about your disability and your need for a reasonable accommodation.

I have thought about this many times and would like you to chime in on whether you feel it would work or be a complete waste of time.Expired Listings: I have access to these as an agent.My thought was to knock on these property owners doors or send them a letter with the following....I will purchase their property Cash and pay to fix it up to get the highest market value.  

Many of the worst loans; negative amortized, balloon payment loans, etc were presented as viable  loans to people who could not afford them.

Put it on your emails, letters and business cards.However, use the SEARCH feature on BP looking for 'website' for some considerations first.

Finally, show that you have respect for yourself and capitalize your name and the letter I.  

Might consider a letter addressed to  you with questions.
