A city Independent Budget Office report examines vacancy data from the state’s housing agency amid concerns of "warehousing."
Why? Because apparently they need some more incentive to keep units occupied. Also, even though a property might be vacant, there's still imputed rental income there. Its owner is just receiving it in the form of enjoying the unit for himself instead of receiving an actual rent check from a tenant. That imputed rent ought to be taxed like any other income.
There are lots of ways to tax landowners, but ultimately they all punish landowners for existing (which is a great thing for society) so instead they become weird neo-liberal market based schemes like tax credits for entrepreneurs who own land in a disadvantaged area for at least 3 years. so that the people that will be targetted by the tax are able to avoid it by claiming that they also own the bodega in their slum, thereby making them an entrepreneur.
Ultimately it's not that the people proposing these taxes can't come up with better tax schemes, it's that they are paid to come up with ridiculous schemes that are designed not to eliminate landowners.
The solution is simply for landlords to keep their units occupied and they can increase occupancy rates by lowering rents, which will also have the effect of lowering their tax obligations. I'm not sure what you think the problem is.
That's certainly the preferable solution, I guess it's worth asking if it would work out that way.
So for example, I own 100 houses and I earn £100 per month for each one. (Values for purposes of illustration only!)
Let's assume 10% are empty at one time.
With an income of £9,000 per month I'm paying 20% tax on that, £1800.
Up that tax to £2000 under this scheme, costing me £200 per month.
so do I drop rents by £5 per building which is going to mean my income changes to £9500 minus £1900 tax for a net earnings of £7600
Or do I increase rents by £5 and keep running with 10% empty buildings? Earnings are now £9450 with a tax bill of £2100. Net earnings of £7350 while holding onto hope that I could rent out some of those other empty buildings?
Put simply, if I'm the kind of person who owns a 100 buildings do you imagine my instinctive response is going to be to cut prices or to pass on my costs to tenants?
