I'd be happy to provide an "est. value" of your home. There are at least a thousand Realtors in the Lititz/Lancaster area who would love to answer your question. I wonder how many really care enough about you to really help though.
My question is, "Why do you want to know?" There is a reason your asking. If you can help me understand what your trying to achieve, I can help you achieve it.
Final thought... whatever the "est. value" is, it will eventually be determined by "what the market will bear". If you want to maximize the value of your investment, you need an expert. I'd love to listen.
