So, we've done business before on pre-listed homes and this time you ask me to do a BPO on a home that is already listed and is in fact, under contract. Sadly, I must turn you down-- flat! Wipe your crocodile tears and let me splain myself Lucy. Delaware is what is referred to as a Safe Harbor state, but only for the purpose of listing a property. Under Delaware Statute my good friend, specifically Title 24, §40, a Realtor is not allowed to complete an appraisal, even if you call it a BPO, a Comparable Market Analysis, a Price Evaluation, or any other technical term for any purpose other than listing a home. Don't do a property valuation and call it something other than an appraisal and assume you're ok, you're not. Conducting a property valuation, regardless of what you name it puts you in Danger Will Robins, Danger, Danger! Don't skirt the law because the penalty is pretty darn severe, and more important, it's unethical.
