Normally when you own a home 50/50 with a co-owner, at the time of sale, any & all proceeds are split down the middle, UNLESS, you had an agreement in writing with the co-owner at the time of purchase, as to how future sale proceeds would be split. Like, maybe they originally agreed to receive 20-30% of future sale proceeds.
I notice that over time, equity was taken out of the home at times of refinance, in a sense, you have recouped original down payment monies. 1/2 of the original down pymt, from what I can see amounts to about $14K.
I can create $14K in higher sale price from my property presentation & professional photography alone.
My office is in Huntington Beach, I could come by & talk to you some more about this & if you have it available, review with you, your original purchase documents.
Shoot me an email directly, if you'd like to talk about it further, I don't look back on this same Trulia posting for answers after mine or Replies beneath my answer.
