The appraisal value is absolutely important when using lenders. My house appraised for 25% less between two local appraisers within 5 months of each other - the higher was during low housing movement. This forced me to bring in even more money and nearly caused the seller to drop and wait for a cash buyer (common in high retiree areas).
That appraisal value is not terribly important to retirees though because they tend to buy for keeps instead of caring about resale value as much as, say, a first time home buyer would.
