If appraising were a timed event, such as track and field, you surely would have "won" over the appraiser who took longer to measure the house. Since it is not, some are comfortable at a diff pace than another.
Nothing wrong with efficiency or using modern technology, but it gets to a point where those who rely on speed as a business model start looking to it to ever increase the bottom line at the expense of thoroughness. You are a prime example, trying to squeeze out more and more, ultimately turning to an outscourcing service such as Dustin.
In appraising, mortgages are for for 30 years and hundreds of thousands of dollars are at stake, plus the home buying is the biggest decision many people make financially. I think it's wrong to skimp on results for speed, this is not a hamburger, this is somebodys's equity and future at stake. Speed as the ultimate goal is a direction that is detrimental to the profession.
Ways to increaser profit: specialize in high end/complex properties, take on associates, or get the cert gen license or an SRA designation.
Beyond that , one has to realize there is a cap on earnings as an appraiser. As a single practictioner, res only appraiser, there is a limit to what you can earn and do a decent job on reports. If you can't accept that, get a side business, flip houses, trade day stocks, or go for a field with unlimited earnings, such as comission sales.
A nurse does not earn as much as a doctor. Some make very good money, if they specialize , such as surgical nurse. Stil,l there is a limit to what even the most specialized nurses can earn. A doctor earns more because of education level, higher liability and responsiblity etc.
Appraisers are not doctors and we are not lawyers. If you are ambitious, go to law school on the side or become a stock trader.
An appraiser rushing through reports to crank em out is like a nurse piling on shifts and bleary eyed, rushing from patient to patient, not knowing who is getting which meds etc. There is a limit to how "efficient" anyone can be,. Certain professions have certain ceilings of pay, and a res appraiser can earn very good money but unless they form an AMC or lock up a client, there is an earning ceiling.
