I really like the interface. I think if you have enough properties listed you can't fail. If it was me doing this the next step would be employing local people responsible for taking care of schools in their region. The only expense here could be legal fees for drafting a contract template making sure those people are self employed "suppliers" paid a percentage of profit their activity generates. This way you wouldn't need to worry about all other costs associated with employing people.
Also, why not talk to few large property listing websites like (UK examples)rightmove.co.uk or zoopla.co.uk to partner with them? Those guys get fees when properties they list are filled. It is in their interest for them to be advertised as widely as possible.
Or alternatively create another type of a user. An estate agency. You could have hundreds of estate agents sign up and list properties on your website paying extra to make them come up first etc.
