Here's how it worked before the internet: You the property owner would engage a local estate agent [realtor] and they would find tenants for your property. There were both short and long term rentals. Most of the time it would be rented out to someone local. But if someone from another country wanted to do a short term rental, they would contract a company who would have a presence in the foreign country and would in turn be able to contact local estate agents by telephone, get particulars sent through the mail or fax (or if it was really urgent, read out on the phone), and these would find their way back to the prospective tenant.
Sure it's not as smooth as clicking on a website, but it was still a thing that was done.
(In fact these intermediary companies still exist and are still used especially by businesses that want a full service and don't want to deal with the randomness of Airbnb. I knew someone who worked in a Japan-England company back in the 90s http://www.redacstrattons.com/)
You couldn't misrepresent the effect on regular working people more.
