Legal Question in Real Estate Law in Pennsylvania

Generally if someone made an offer and put down a deposit then you should not entertain any other offers until you reject the offer. Of course if multiple offers come in you can pick the best. The Realtor can certainly take an additional offer but the one that came in first should be rejected before responding to potential Buyer. There is no contract in real estate until both the seller and buyer sign a written agreement of sale. A verbal agreement is difficult if not impossible to enforce. However it sometimes can lead to litigation which can tie up the property. You may want to have an attorney involved because the agent though representing you many times is anxious to close a deal in order to get their commission.There is insufficient information togive you a more complete response and what i have indicated here is only the general law as all situations are distinct.
