First to answer your question. Portola district over the past 6 months had an average list price of $651,577 with 1,392 SF at an average list price of $490/SF. Sold after 57 days on market at average $647,707 or $488 /SF.
The whole city for properties under $700,000 had an average list price of $565,087 at 1,215 SF for an average list price/ SF of $489. Sold in 57 days at $565,072 or $489/SF.
Now what is going on in the market where you live? When the demand was higher than it is now more people were looking in your area, Visitacion Valley and the Excelsior. Now that credit has become very tight there are fewer buyers in the market.
So what to do if you want to sell or have to sell? You need to make your property rise above the others on the market. You have to attract the next buyer or better yet all the buyers that are ready and willing to buy in your neighborhood.
You live in a very nice and unknown neighborhood. Old families of Irish and Italian heritage, good weather, great access to the rest of the City and the Peninsula, you can grow fruit and vegetables in your yard probably, but it has it's draw backs too. No vibe like Noe or Bernal, no resturants or coffee shops within walking distance blah blah blah. That is to say that you can't attract all the SF buyers, you need to know who is buying in your neighborhood and then focus on putting out the honey to attract them.
Obviously the main sweetner is the listing price, but curb appeal, interior presentation and rear landscaping is also important.
The listing price doesn't neccessarily have to be what you want for the house. It's a tool to be used to bring in as many buyers as there are in the market for a house in your neighborhood. Here's the scenario; you prepare the property to look better than the competition, and you go on the market at a price that is better than the competition. Buyers flock through the house on the first open, see all the other buyers flocking through and want to own your home above all the other houses in the neighborhood. They go home and they talk to their Realtors, the Realtors tell them that the house is underpriced for the market and that if they want it they will have to offer market or better to secure it over the other buyers who are having the same conversation with their agents right now.
That's the gist of the SF market. Beware of overpricing. Our screwy little market does nothing with over priced or even market priced homes in a downturn. They sit and wait till the seller gets desparate and lowers the price. Then when the price shows value they step up and pay market for it. I've seen it over and over. An example is you price it at $748,000 nothing happens till it is lowered to $698,000 and then an offer comes in at $735,000. $13,000 less than the original list price but $37,000 over asking at the time the offer is made. They will pay you market price but only when it's offered to them below market.
There are nuances to this stratagy and I won't give away all my secrets on a public forum. I also won't say contact me because if you want to you will.
