Zillow has an estimate of $466k. If you ask a local real estate agent in your area for a CMA report you can get a better estimate.
Keep in mind, that comparable sales don't always take into account the condition of the home. If this home is in need of a lot of work, then the actual value could be lower than the comparable properties. If it is in pristine condition with desirable amenities, the value could be higher than the comparable properties.
