The one people shared in my initial days was - just get anything that looks good on GoDaddy / EstiBot Appraisal. It will definitely sell. Later, I realised many things that were responsible for an Appraisal such as past data, keywords, what is the value in the end-users mind. I also had an experience where Appraisal showed the value less than $100 was sold for more than $1500 to the end-user. What was that one worst recommendation you have heard people sharing?
