Historically, because of the wealth of resources available online, the selling and buying of homes was a face-to-face process. The RE agent would sell properties, and you would go to see her/him to buy them. At most, advertisements would be used to announce a sale.
The majority of the process was done in the estate agent’s home, and with varying degrees of investment, they would prepare the materials (leaflets, models, plans, prices…), and the space itself to be sold (Waiting and meeting room). In the best-case scenario, they would also be able to provide a show flat, to be visited by potential buyers.
That all means to say, physical methods were all used for a purpose:
To obtain the needed trust of the potential client before building what they wanted to sell, thus anticipating the future.
This all came with an added difficulty. We’re not talking about selling shoes here. The challenge is closing what is likely the most important deal in a client’s life.
You don’t lose anything. Invest the same but with new methods.
