You’re going to get excited over a $25,000 difference in offers? You can easily make that up with concessions.
I would tell you if this was an outrageous price, but from looking at the sales in the area I can definitely see where the seller is coming from. The photos depict a very nice kitchen remodel and back yard improvements. Its true that there is a pretty big range of pricing in the area but the lower priced homes don’t appear to be as nice.
Did you check out the closed sale at 1811 Friedrick? Same side of the street and a similar sized house. Not quite as much curb appeal if the photos are an indication. Somewhat inferior kitchen. It just closed at $550k. It’s definitely a comp any appraiser would be looking at.
Counteroffers are made to be countered. If you’re serious about the house try going to $560k and see what happens.
