Call one of the local Coldwell Banker offices near you and ask for the manager and have them tell you about "Schweppe" and what it can mean for getting your listing to sell rather than languish.
I work in a small market (our mls had 1200 sales last year, total), and agents in our area generally know what appraisers have excellent reputations....Appraisals from these appraisers carry a phenomal amount of weight and credibility, and it definitely helps establish value in an uncertain market. I also tell my clients to be delighted if they get an offer for an amount close to that appraisal.... but to expect to get offers for 5-10% below that number.
Yes, CMA's are OK and are effective at establishing a list price. Certainly, one must look at competing homes for sale...right now that is of utmost importance. But unless your CMA includes adjustments for depreciation, functional obsolesence, landscaping and other upgrades in your comparisons, the seller will always say," but my house has.....and this one doesn't!
A second opinion helps...and seeing it all in black and white, twice, doesn't hurt either!
In fact, it can be worthless if it was done last week.
I suppose you could pay to have it updated, but what is the point? The buyer's lender *certainly* won't accept it.
