Yes there was a company offering a rent guarantee insurance. I think it was called Rentassured.ie but stand corrected. I'm not sure if they're still providing insurance. They had a link on the Allsopp ( now bidx1) website but dont know if connected. The tenants had to undergo a type of credit check. The premium was reasonable at the time. The Lease had to be in writing with tenancy registered with RTB. I thought it was a good idea particularly if mortgages buy-to-let. I'm not sure if premiums could be written off against income tax?
