At one time Estate Agents were usually surveyors as well, so held a degree or professional qualification.
Yes, I'd agree with that Jalima. I remember when we bought our first house in the 1970s. The estate agent who showed us around was extremely articulate and knowledgeable. He pointed out lots of technical things, like air-bricks, drainage, structural bits and pieces about the property we viewed (and bought) to husband. He also made us aware of the work needed to bring it up to standard. He also knew the area very well and was a font of knowledge.
Last young (sales) man was very young, a sharp dresser and he had a digital camera. I was the one advising him about where to stand to take photos to show the property at its best etc. His written description of the property could have been taken from any estate agent's list of stock phrases unfortunately. He also tried to get us to sell at a silly price, much below market value. He desperately wanted the commission. I got the impression it was all very cut-throat and that estate agents were about young people desperate for properties to flog to earn themselves a cut of the fees. They were sales people, not property experts. Our asset paid their wages.
We felt more than a bit ripped off tbh. The fee was huge. Our fault for not doing our homework and engaging the first bright young thing to sell it because he was so enthusiastic. It had been many, many years since we'd dealt with estate agents and things had definitely changed, and not for the better.
