You will need someone to review your offer. You can hire an attorney to help you with this. Just make sure every aspect of the transaction is agreed upon in writing, including agreed concessions or repairs. A mistake many people make going at it alone.
The FSBO may be willing to compensate an agent. Often they are relieved to have the assistance for the buyer, because they do not have a clear understanding of how the process works either. If not; you may want to strongly consider, hiring a Realtor. You would be surprised at how often this will actually save you money, avoid disagreements, and contract fall thru. Time, energy and peace of mind. It really could be worth having someone on your team negotiating for you.
I wish you the best of luck in your home search.
Price is not the question... the question is does the seller have a legal title to transfer to you at the time of sale. The only way to know this is with a full professional title search .
