Regarding Realtors and the SoWal real estate market in general: if you absolutely don't have to sell, you will likely be very happy you didn't sell in just a few years. There has always been, and always will be, a very strong allure to the SoWal area. Once the PCB new airport opens, there will be easier access from major cities like Chicago, DC, NYC which will increase awareness and appreciation for this area, driving demand back into the market. Supply growth has slowed significantly, although there are still some large condo developments underway.
If you absolutely must sell, you should not depend upon a realtor to tell you where to price your property. The realtor will be torn between market reality, keeping you smiling, and putting a price on it that could generate a commission. Blaming a realtor for your property not selling is ridiculous. It just means that during this given time your property is not priced according to what the market will bring, or you have an average property with nothing that distinguishes it from others in a special way. Your price will have to be compelling OR the property must be very desirable or special to set it apart from the other competitively priced properties.
No, I am not a realtor. I bought my first SoWal property 6 years ago, the second 4 years ago, the 3rd 6 months ago. If I had more money I would be buying today.
