We had a net increase of population by 106,100 for the year ending April 2007. Link
Immigrants don’t usually buy houses so there were 67,300 looking to rent places. In a best case scenario (for builders), you are looking at two per household, which means that at best 33,650 properties can expect to be housing new immigrants. A more realistic figure of 3 per household means approx 22,000 extra properties required for rent.
The 38,800 born last year are all wee nippers and thus won’t be buying houses or renting just yet. Let’s just assume that they’ll be absorbed by keeping the 2.8 per household figure that we have for Irish families. That means 13,800 properties are required to house the wee kiddies born.
To look at it from another angle.
52,500 were born in 1990. They turn 18 this year and can reasonably be expected to require homes over the next decade or so. Assuming that number was not decreased by their parents emigrating etc, and that they all get married and live as couples they can reasonably be expected to require approx 26,000 homes over the next decade but for the purposes of this thread, we’ll assume they buy all in one big chunk which means 26,000 “this year”.
Nowhere do these figures remotely justify building over 80,000 homes a year. If net migration drops, which is almost a certainty, a huge amount of the real demand for new housing disappears into thin air.
These figures don’t even take account of the annual death rate which predicts 28,000 deaths in Ireland per annum and even if we assume they were all married senior citizens with no children, they would be expected to release approx 14,000 homes a year onto the market.
Doing the sums:
+22,000 houses required for new immigrants to rent
+14,000 houses required to house new babies
+26,000 houses required to house the 18 year old generation
-14,000 houses released due to death of occupants
Thus 48,000 new homes required (in a best case scenario for builders) and if immigration slows, this will drop even further.
If migration was to become static, then you’d be looking at only 26,000 homes being required per annum.
250,000 is a conservative estimate of the number of empties in Ireland right now which could in theory house the next five years worth of demand, before you consider that this empty overhang is likely to increase even further during this year.
I’ve deliberately set this up to give the rosiest picture possible for builders by using multiples that would up the number of homes required.
Flaws? Mistakes? Thoughts?
