You can put it on the market now. You are right with having a unique position without any inventory and competition. It will not hurt you in any way to pull the listing and put it back on the market later on but I don't think this will be necessary since you are in a very desired area. Most important is the pricing strategy. Your Realtor will help with it. Good luck to you.
There are different ways to structure when buying and selling. Ideally, if it is possible, you would find your replacement property first. That way you are not under a time crunch to find a home, and you can take advantage of the current market as a buyer. You may have to take an equity line out on your condo in order to make a down payment.
Once you have an offer accepted on a replacement, you can prepare your condo for the market. Most likely, unless you already have the replacement, that will bring you to the beginning of next year as we are already in mid November, which will be a good time to sell. You will also be selling a vacant and hopefully staged condo which very often sells faster and for a higher price than those that are not presented that way. Doing things this way will mean that you will have two mortgage payments for the time it takes to sell your condo which could easily be two months (including escrow period).
If you are not able to do that, and you need to sell first, putting the condo on the market now would not hurt your chances of selling next year if it did not sell. It is clear to people that the market is in a transitional stage; buyers will understand that the timing was not right. Having said that, it sounds like your unit has all the components of a desirable property. Good condition, parking, and an outdoor space are all key features; I'm sure that is what attracted you in the first place. The style of the building and the exact location (block) are also key factors.
If you want my thoughts on your specific property without giving away that information publicly, please give me a call. My partner and I can come by, have a look, and talk strategy with you.
Head down to E'Angelo's for some good pasta and wine (water for the misses). Forget about selling this year. Watch the market over the next few months and get your home ready to sell in spring. Buyers still have the yips about buying and are in a look and see mode. You should be doing the same. You might get an equity loan lined up in case that larger home comes on the market and yours isn't ready to sell. To ideally time it (and it rarely is timed ideally), I would look to buy in February and sell as soon as you get into contract on the buy side. Since you're in Pacific Heights and I assume a reasonable location (my wife lived on the corner of Washington and Baker), selling your home will be easier than buying. Good luck!
If you are able to sell and take a smaller profit, see if you cant make it up on your next purchase and get a good deal.
