Hey Johnny - Danny T here. (Disclaimer - this is my opinion, I do not represent anyone in any transaction related to the property in question.)
I have a listing right done the road from this one - different neighborhood, but similar issues. Remodeled, updated, priced seemingly correct, or "in the market". One problem that I see, with your home( and my listing), is that the square footage is on the top-side of that particular area. Average homes sold in last six months were closer to 15-1600 ft. Yours is bigger. A bigger home priced at the same square footage, which seems reasonable, ends up being the highest priced listing. The average buyer tends to buy a home that is in the middle, or below middle, when looking at square footage and price. Someone really has to love the home, or love the area to go against that...OR, love the deal. In other words, they want to buy it cheap.
In the Buyers market that we are experiencing, price is king. We are also moving into the winter months. So active buyers right now are very cocky... they want a deal, and will likely get one.
I would need to actually see the home, but just based on what I see in the MLS, and what is going on in S.A. - its the price. Homes that area selling are priced "ahead of the market."
I will add that during this more difficult time in the market, you do need an agent and a company that is aggressive in every aspect of the word. For instance, my office has gone from 10% market share last year, to 17% market share year to date. That would be an example of aggressive. I could brag some more, but you could just visit my website, or email me and I can give you more examples. In any case, you either need to get with your agent (assuming this is your home), or asked to be released from the listing agreement and find someone who will get the job done. I know the other three agents who have responded, and they are all excellent Realtors. You have a lot of options.
All the best!
