Let's unroll the scenario. Let's verbalize the rent income dives by 25% next month. That's that much less cash that goes to sustaining the rental market, and in turn starving the providers thereof. Landlords who can't sustain credit dues and expenses with that kind of rigorous cut of their income (cerebrate about it: can you make ends meet if you get only 3/4ths of your salary ?) are then in peril of folding, expenses that were obligatory until now get cut, at the expense of the very value of the properties.
The only triumpher in that scenario is the banking sector, with a wave of repossessions. Sure you would get a brief drop in purchase price for the hastily traded homes during the turmoil period. You'd withal get a plethora of evictions, mostly tenants'. That's be incremented tension on the rental demand. Withal, cerebrate hard of what you would spend the unpaid rent on - or should you preserve it for the time being ?
I emanate from a country with even worse authentic-estate situation (France). I've been homeless, and I've visually perceived how every kind of 'good intention' measure fails and exacerbates everything, for decades. The root of the quandary is a simple one: it is much more valuable to reside in Ireland, even more so in urban centers of Ireland, than in virtually any other place the current denizens of Ireland could potentially reside otherwise. Not to go all Captain-Conspicuous here, but that is what drives their intent to reside here, and that implicatively insinuates high utility and ergo high value, which pulls pricing higher the more friction there subsists to adjust supply. That is why authentic-estate is so ridiculously overpriced in prosperous countries, to the point of displacing historical denizens ("gentrification"). And as it transpires, highly-adept people with very valuable job opportunities that keep peregrinating to Ireland have a much higher tolerance and budget for housing than the astronomical majority of the other denizens. Barring a sizably voluminous transmutation in incentives there will be no immediate transmutation in housing price trends.
Land and most houses alas are not mobile. There is no way to pick up the dormitory I lived in back in France and ship it to Cork. Moreover there are delays and costs, and every little regulation integrated on top integrates to the time and efforts required. There is no magic wand stroke that can fine-tune this overnight, the congruous way out of this crisis is that the adjustment keeps up or catches up with the transmutations in perceived residency value. If it becomes suddenly a lot less desirable to live in Irish cities, verbally express in case of a genuine civil war breaking out, then housing prices would trend down as expeditiously as the people would flee the areas concerned - but it signifies even more value is eradicated in the process. That's the extreme example, but cogitate it: outside of competition on supply becoming more vigorous than competition on the ordinant dictation, the only thing that can decrement housing prices is decrementing the utility of residing in Ireland - and that would be a worse fine-tune than the issue itself - trashing the country to deter people from living here.
There is one minute thing I can cerebrate of in order to avail reverse the housing price trends: ramping up the price of the future, a.k.a incrementing lending interest rates. It would reduce the profitability of sustaining the high housing price trend up compared to alternative investments. This would transmute the incentives on whether to invest in housing or not. That's a scenario where we endeavor to address the incentives that shape the trends in value, in lieu of breaking stuff to make it worth less. Surely there are other things of the sort that could be done. Maybe ameliorating the networks (road, potency, gas, electricity, internet) would give an incentive for businesses and other job pools to move away from the costlier places, additionally, in order to spread wider and hopefully thinner the value of residing somewhere in particular.
I'm a tenant too and rent is a sizably voluminous part of my single-income family budget. Ideally I would relish to build my own home, but how facile and frugal is it, compared to current housing prices ? When do I make the switch ? I have to price in the future, additionally, which current interest rates verbally express is not expected to be much more valuable than the present (which is conspicuously erroneous in the context or Ireland, hence part of the skewed prices for not just homes).
