I understand that making a price reduction, especially at such a large amount, is concerning at best. But your realtor should be able to show you the facts of record to support the necessity. What is the absorption rate in your price range? I mean how many homes are selling divided by the number of homes for sale in your price range. If that number is high the only way to counter it to comply with your timeline is through a price reduction. That opens the potential buyer pool to a wider number. Best of luck!!
