The slowdown in the property market here could present its own opportunities, anything that helps sell properties might make a good business opportunity.
In the US and many other countries it is common for a property for sale to have a brochure available in a display box outside the property. This means that someone passing by can obtain a copy of the sales particulars without contacting the agent. However I have never seen this in Ireland.
To find a supplier for the brochure boxes just search google or ebay for “Outdoor Brochure Box”. You can find them for around €10 each.
Then it would be a question of approaching auctioneers, estate agents and letting agents and offering the service of setting up the brochure boxes outside their listed properties and then to go round replenishing the brochures a copule of times a week.
You could probably get the agents to pay say €10 set up and then €5 per week per property. If a property is typically on the market then this might end up costing the agent or vendor around €70 which is pretty low compared with other advertising methods.
If you built up a round of 100 to 200 properties at any one time you could generate a significant income. The investment for this kind of business would be low and it should be possible to build a high level of repeat income by running a professional service and building a relationship with the estate agents.
