Denbighshire looks set to be the next county to ask owners of second homes and properties which have been empty a long time to pay a council tax premium.
Wrexham, Flintshire and Powys already charge an extra 50%, with Anglesey and Ceredigion charging 25%, and Conwy and Gwynedd are yet to decide.
Denbighshire councillors will next week be recommended to follow the example of the first three and impose a 50% premium.
In Denbighshire there are believed to be 946 long-term empty homes, 502 of which have been vacant for more than 12 months but only 147 would be eligible for the extra charge. That would produce £99,480 in income.
There are 250 second homes in the county, of which only 73 would be eligible for the premium.

Plaid Cymru says it'll work with the Welsh Government to 'take action' on increasing the amount of affordable housing available. The party is calling for one step to be giving councils the right to double council tax on second homes. Local Government spokesman Rhodri Glyn Thomas said:
The recently finished consultation on council tax for second homes offers a positive way forward. As a matter of social justice and the redistribution of wealth, those who can afford to own multiple properties may be required to make more of a contribution, in order to help younger people in particular get on the property ladder. We also then need to look at the forthcoming powers over stamp duty.
There is a clear crisis in local government finance at present and there should be no stone left unturned when it comes to identifying new sources of revenue to help councils deliver their goals. The way forward is for the Welsh Government to make a positive statement on council tax for long-term empty properties and second homes, so that we add a clear rural dimension to the Government’s existing work on affordable housing.
Plaid Cymru has a strong interest in securing social justice in rural Wales, so this is something where we want to offer positive solutions rather than just identifying the problem.
He estimates that doubling council tax in Gwynedd, for instance, would raise £5m to be spent on affordable housing. He rejected my suggestion that the amount would shrink over time, saying that second-home owners are unlikely to sell up simply because of council tax.
He also said he'll be holding talks with Housing and Regeneration Minister Carl Sargeant to see if the two parties can work together to increase affordable housing. I asked him when they'd take place but he would only say 'they're about to happen.'
