What can I attach to a POS agreement!?

[Devin Amstutz]

After watching the Watson video here on BP about "marketing no no's" I have a better understanding of how to market the property without breaking laws. Can not use the address or anything that would lead an investor to believe I own the house or upload pictures. I can only market the equitable interest I have in the contract specifically. So for example a craigslist add could say "great deal on beautiful contract, 3/2 (3bd/2b), Toledo Ohio, 43614, 2,500 square feet call immediately!" Am I right or would that still not be a very good? Here's my actual question. I was reading yesterday online that since you can not use pictures on your add to market a property you don't own you can sign a piece of paper (can not remember what it was called) with the seller when you sign a purchase agreement and it will be attached to the POS and this allows rehabbers, investors, estimators to go to the house look at it and get estimates. So if anyone could help me with what it's called that would be great. I thought I was abundant, addudant something like that.
