I just finished the first round of a direct mail campaign. This will be my first property and I targeted towns/properties that I plan on buying as an owner-occupant. 

I was able to generate a few hot leads that I'm currently working on. I mentioned in my mailer that I'm already pre-qualified. One of the sellers I spoke with asked to see a copy of my pre-qualification letter before he shows me the property. I believe I've developed a good rapport with the seller and he admitted that he has never done a deal off-market before so he wants to be cautious. I assured him I would be transparent and act in good faith throughout the process, but I'm reluctant to disclose the full amount I'm pre-qualified for before we move towards any potential negotiations because I believe that would jeopardize my ability to negotiate a great deal as opposed to a good deal. 

I have a pre-qualification letter from a previous offer and my initial thought was to white out the specific numbers/loan type, then scan it and send it to the seller. However, the seller also mentioned a ball park price that he would entertain for an offer, my other idea was to request a second pre-qualification letter based on the ball park price he mentioned. 

Does anyone have any thoughts or suggestions on how to best handle this?

Thanks in advance.
