Seminars will take place in March and April for homeowners in the borough to find out about letting their properties during the Olympics.
Estate agents Haus Properties will be host the first session on Saturday, March 3, at its office in Wandsworth Bridge Road.
Agent Jamie Lester said: "Our market research proves that short term rentals provide more value for money than a hotel.
"However, there are lots of things to bear in mind when considering letting, for example, your mortgage terms might have a clause about letting the property. There are also the correct insurance policies to consider, and any money made will have to be disclosed to the tax man.
"These are just a few of the issues we will be addressing in the seminars, as well as looking at the plus side of how homeowners can cash in."
