There were other reasons to close escrow in 2020. It has to do with a Biden wins and the democrats taking the congress. He is purposing raising the capital gains tax!! Big effect. In California we already have one of the highest long term capital gains taxes in the country. I am losing out on our Obamacare tax credit for this year (about $20,000.) but may gain if the tax laws are changed. Looking at it from all sides. The buyer said if we didn't close soon they have their eyes on another parcel. Good price (with no real estate agent...Just our attorney) this seems the way to go.
CA taxes must be a quagmire. much less the fed vultures. Keep Kickin, a good atty never hurts. Better Trades down the road.
I think that you should close it before it expires because the stocks may make big moves downwards too, so as to cut your losses on the trade.
