Should i keep developing this site or sell it? if so how much will be a good price to sell? I registered 2 years ago and it ranks 21 out of 4.5 under keyword "house trading" on google.
I think this domain is worth $xx.xx Maybe around 45 give or take 20 above or below. If thats not enough to you, then develop it some more, get some traffic (to make it more coveted), and sell it. You may want to get it appraised to see what it's really worth. We can tell you what we 'think' all day, but you won't really know or have the backing until you get it appraised. Some websites that do website appraisals are GoDaddy.com and MidFlux.com I don't know about many others that I trust. Check which one's cheaper. They appraisal will make it worth more too! Hope this help, Xinjiang
