If the visitor to your web page sees how much time they’ll have to spend – even if it’s not short – it’ll might make them more willing to read on.
Show an estimated time that it will take them to read the web page, based on an average reader’s speed. Then as they read and scroll down the page, update the estimation of time remaining until they finish, by taking into account both the remaining unread parts and also their actual speed of reading.
Make your agendas are more inline with each other.
Make a large part of the commission dependent on how close to the initial estimate the final price is. This will ensure a more accurate initial estimate and counteract the incentive for the agent to sell quickly cheaper (instead of waiting for a better price.)
