How are you doing? Hope all is well. Please visit my Seller page at http://www.DChomevaluesnow.com to get a free Comparative Market Analysis of your Silver Spring MD. When you give me your full address,I would help give you an idea of how much your house may be worth?
Very hard to tell without actually seeing it. My advise would be to contact a REALTOR and ask for a comparative market analysis and using comparables in the area, they will give you a rough estimation on the best market value. The other alternative is to hire an appraiser.
