My suggestion is you follow someone here that is established, learn by asking specific questions...that in itself will manifest into a form of mentor (if the recipient is willing to answer you questions consistently or timely)Good luck, @Zack Ellard

Your comments about acquiring real estate in strategic locations and wanting to rent to voucher recipients for the benefit of guaranteed rent may be at conflict with each other.

I was tired of the low response rates on marketing so I did something about it and created a program that creates personalized landing pages (including Audio and video messages) for all my recipients of Direct Mail or Email.

What do I put for recipient...name?

Fortunately, in my market we have more recipients than landlords.

In my market, we still believe that welfare recipients shouldn't have nicer housing than people that work full-time, so Section 8 pays less than what I can get on the open market.

Although I did learn a little and met some awesome folks I feel as though I learned more from this website and other free resources on the internet than I did from what I found to be an outdated home study course and this extremely high-level Three Day Seminar.The seminar I found to be 10% focused on education and 90% focused on selling the coaching programs that are designed and intended to guide the recipient to earn in upwards of $100k/ per annum in investing.   

For the same or similar reason you doubt the effectiveness of YellowLetters for Realtors® is why it would attract a positive response from some recipients. 

Your point of "Put yourself in the place of the recipient.

I am looking for a vendor to send out small volumes of letters (anywhere from 5 to 50 at a time) without using a window on the envelope.So far, I have come across click2mail and some of the other larger sources that incorporate one or two window envelopes for the return/recipient address, and I don;t want that.I do know several vendors that can send letters with no windows, but they have very large minimum orders, and I want to send letters on an as-needed basis.Does anyone know of a source that can send small batches of letters with no windows on the envelopes?
