Please check the URL carefully and you will see that the property is in the SOLD section of homes in Arlington and the listing is old. There is nothing to update. The picture was uploaded some time ago.
Your purchase last September does not agree with the price you put in your question and your price does not account for the seller concessions paid for you out of that price.
You may find other estimates of value on Zillow and other websites, but only an appraiser can give you an accurate valuation or a Realtor can give you an opinion of value currently.
