Was the home for sale by owner or did you see it through the listing agent? Either way it is a good idea if you get your own representation. Do you know any Realtors or can you get a referral from a friend or family member who has bought or sold lately? Having good representation will insure you don't overpay and they will also cover all the details, i.e. closing date, time of possession, inspections, disclosures, taxes, etc.
It is a great time to buy, good luck on your offer.
Also, the commission for the agent you use will be paid by the sellers, not you.. So, there is only advantages for you in hiring a good realtor to work with you.
