This thread is hitting a raw thread with me at the moment.
Regretting a couple of rejections I made to unsolicited offers for 2 domains 6 months ago.Would gladly accept those offers now.
trouble is I get a little too attached the longer I hold a domain.
My best and most lucrative have always been the quick turnarounds.
Interesting thing is of my 4 biggest sales ( 20k to 60k) only 1 of those domains are being used at the moment and that's the cheapest and they recently enquired whether I would buy it back.
Seems like its best to sell when you can.
