The proper way to achieve you goals, is to enlist the help of a LISTING AGENT:
There is just too much money involved and the Pitfalls are numerous.
Your place could be "WORTH" $500,000, or it could be $800,000; there are many factors involved including the CONDITION, the AMENITIES, and the NEIGHBORHOOD.
A CMA will take all of these into consideration and give you good numbers.
NOTE that I am in Fresno; I am not vieing for your LISTING: I am telling you straight.
Nationally, we estimate that selling without a Realtor will NET 8% less; and if a LISTING costs about 6%; you can do the math.
Good luck and may God bless
A CMA specifically done by your Realtor who I am assuming is a top area specialist for your home in San Francisco speciafically working and knows that district well will be able to give you a more accurate & realistic suggested listing price.
If you need an area specialist for your SF home let me know, there are several top agents in that area I can recommend to you. Good luck!
