Rents did decrease in the absence of RPZs. Since RPZs have been introduced, they have only increased.
They also increased in the absence of RPZ's. This is obvious, from the screenshot. Again, I ask you, are you saying that the government introduced RPZ's during a period when there was no increases in rents?
I'm not disputing that rents have continued to increase since RPZ's were introduced. Again, I have to say, I think you are arguing points that are simply not there.
My underlying point is that the structure of the Irish rental market is not suited to boom, bust, boom, undersupply, oversupply etc. I identify small LL's who take properties for one generation into the rental market and then sell those properties (on retirement etc) which reduces the supply of rental properties as part of structure deficiency - nothing personal on them, they are simply operating in the conditions we all live in.
We now have the double-whammy of government interference combining with rental properties of small LL's where many were obtained during the free-flowing credit Celtic Tiger period and are now ripe for sale back into the property market in the absence of similar credit that the CT had to facilitate new, prospective landlords to sustain the rental stock.
Small LL's, through no fault of their own, do not have the capacity to ensure the continuation of rental properties to be available as such for future generations.
Corporations, Governments, State Agencies have more capacity to do so, as by definition they intend to exist beyond one generation.
That said, to show I'm not anti-the evil, greedy, landlord, I made a simple proposal that I would consider may go some way to keeping a supply of rental units to meet the demand of the rental market, providing stability for all in the sector and facilitating the small LL to remain an important cog in the rental market.
Furthermore, imo, it provides for a decent yield on the investment for the landlord, it provides for capital gains on the investment. It provides for security of tenure - up to lifetime tenancies, it provides for a real competitive alternative to people settling down with wage-sapping mortgages for 25-30yrs.
I'm not saying it is a panacea, not saying it is wholly viable, but surely it is at least worth a consideration if indeed it would provide for a stable stock of rental properties in the State for multi-generations?
