Yes, but with a house what it sells for is affected by location, condition, the market, how good the work is etc, not just the work you put in. It is the same with websites. If you put a load of work into a site that no one wants it won't sell for very much.A person can sell a house if they put equity into it. Basically, if they fix up the inside and outside of the house and property. Do you think this business practice carries over well with websites?
