Call three local brokers to do a price trend analysis or BMA on your home's value to give you an immediate idea of what your home is worth. I would also explore if any homes in your vacinity are going into foreclosure. How many homes in your neighborhood have "For Sale" signs on them?
A suggestion I can make to you if you do decide to sell -- Few home owners go the extra step of actually paying for a bank appraisal to be done on their property - but I recommend doing so if you are serious about reselling. This is an accurate gauge of the market which would be very valuable as a marketing tool should you place the property on the market because your price would be based on factual information.
Good luck in whatever you decide.
Email me if you need help identifying a good Realtor. I work with Top Tier Agents all over the country.
I hope this helps.
