I am selling an apartment building FSBO, what is the best way to deal with realtors.

Mary B. - I am interested in knowing what you have for sale, interested in buying. Please send me the information to Deborah Hicks / Email: dhicks654@hotmail.com.
Thanks,
Deborah Hicks

If the broker reps both sides many would agree to 2.5-3% commission. I don't know what area you live in though, it may be different, we are in Los Angeles.
I would definitely not represent yourself, it could cost you a lot more than a full commission. If you do, make sure binding arbitration on all parties is part of your PSA and to disclose all material aspects of the property promptly.

There are to many factors that could go wrong in a transaction. I thing representing your self if fair, just protect yourself.

Mary - I would advise advertising the property so you get the most exposure, more offers and higher pricing. However, the best way to deal with Realtors is you give them all the proper information about the property and offer them a standard commission fee between 2.5% - 3%.
