I would recommend talking with three Realtors. Have them analyze your situation, both the buy and sell sides, then compare their proposals.
In most case investors have a goal of buying a property for 20-25% BELOW market. Why would you want to sell 20-25% BELOW market?
I'd sell it for the HIGHEST price possible, if it were me. LISTING it 20-25% below market will ATTRACT the investors you are trying to contact. Most investors have REALTORS as part of their team, so if there is a "good deal", they will find out about it.
What investors will want to know is:
-->What is the ARV (after-repair value) of the property?
-->What repairs (dollar amount and list of the major ticket items) does the property need?
-->What would the property rent for?
-->What's the least you would accept for the property?
Hope that helps.

The best thing to do is find a reputable Realtor in your area or the area where the property is located, who not only works with buyers and sellers but also works with investors as not all real estate agents do. They will have a large data base of all different client types which will most likely give your property maximum exposure to potential buyers. .
