What you are asking is "If you take an average price of all the homes in your city, what will this particular house appraise for?"
That is like asking "how high is this plant in my yard? The average of all the tress, shrubs and flowers in my neighborhood is 2 feet.
Do you see that it is not that easy? Much more information is needed.
You need to have someone who is familiar with the plant you are asking about, and has some measurement tools to help you. Call a local Realestate or an appraiser.
Hope that helps.
