I don't know exactly how to find expensive domain. You see ... Appraisal cannot really tell will people buy the domains. I used to have a domain which was appraised $1000 by Sedo (I paid for appraisal fee). It was unsold & dropped. Appraisal cannot tell how much people willing to pay for domains. I've seen many highly appraised domains sold cheap & lowly appraised domains (some are appraised 'reg fee') but sold at unreasonable high price. People says domain which have numbers & hypen are not expensive but I see many has reached 4 digits & more (in USD). People don't buy my domains but when it dropped, they grabbed it immediately. Some say submit domains to as many domain marketplaces as possible. I did but nothing sold. Marketplaces recommend to feature my domains. I did. Nothing sold. Some say develop domains as running sites to increase its value. I did. Nothing sold. Cost & time incurred. Some say hold onto domain longer so that it appreciate over time. But I could see some aged domains are sold at $10 or even lower. Is domaining is not an ideal business? Is domain industry created so that some people can make money? But many make living on domain business ... . Where I did wrong? Could you help me? Go back to the main question: why people buy domains & how much they willing to buy ... But I'm still learning & domaining ... ... because I believe ... ... although my credit cards hurt! I only managed to sell one domain so far & giving away for free another ... proudly in DP BST section ... though I sold it below cost. I still have two more domains on shelf. Those are the last two.
i programmed a software to generate the domains(based on the letters num) beside it check the availability too . so i can provide u with any mount of 3 or 4 letters available domains
