Condition and location are the key. You seem to be speaking from zip 38107, where there is a wide variety of neighborhood conditions. Did you get the $70,000 figure from the tax assessor, or a recent appraisal? Is the home in good conditon with upgrade, and good heat and air? would it be considered a safe and walkable block? Is in a good school district? All these could be factors. Contact me for a no-obligation evaluation.
