Dear Young Kwon:
In order to give a real estimate a person would need to physically inspect the property. Without actually seeing the property, size and condition live in person, it is too hard to be precise. If you want to arrange to get together with me so I can look at it real quick, I can give you a very precise estimate of it's value. Good luck!
