A comparative market analysis or CMA is a valuable tool to let you know truly how much you can expect to fetch for your home. Why not just look it up on Zillow? Please do, but realize property valuation is more of an art not pure science. Ultimately your property is worth what someone is willing to pay for it. Zillow does not take into account your new granite countertops, the awesome walk in shower your master bath has, or even the care you have put into your landscaping.
If you live in Northeast Florida and want a free CMA send me an email firstname.lastname@example.org with your property description, basically what you love about your house. Tell me what will make a buyer write an offer and I will tell you what that offer might be!
