Hi Susan, You should stay with your realtor for representation.
Tell your realtor of the FSBO homes that you want to see, most FSBO's will work with a Realtor and pay a commission. This way, you have realtor representation in your corner. Yes, you will have an attorney to do the closing and make the contract legal after you make an offer that is accepted. But you want a knowledgeable realtor in your corner to get you to negotiate the sales price and get you to closing.
I am able to work with 99% of FSBO sellers and help people buy their homes.
