My Real Property Report is more than 6 months old, is it sufficient ?

The current Offer to Purchase only states that the Seller needs to provide a Real Property Report showing the current state of the improvements on the property NOT that the Real Property Report has to be new. If the RPR you have shows all of the improvements as they currently sit then it is likely sufficient. It is very important to discuss your RPR when you list and not leave it until the closing as it could possibly delay your sale.
