There is no question that a rebuild is a huge commitment, and there are much cheaper ways to get on the water. I’ve only seen a few rebuild threads where the builder actually posts that they’re quitting or selling, but there are many build threads that just trail off long before finished.
Only you can speak to your exact situation. Only you can balance the time and money that you have in your rebuild against the money and time commitment moving forward, plus your life circumstances.
If you sell the rebuild, you’ll never get what it’s worth in your money and time. On the other hand you keep the wife happy, and you can hopefully get something seaworthy that can get you out on the water.
