I'm from Dublin, where house prices were sky high with first time buyers struggling before the 2008 crash. Let me explain how that went for FTB.
Prices crashed so no one sold unless they had to, massively reducing supply.
Lending reduced hugely, making it much more difficult for FTB to get a mortgage even at much lower amounts.
So nothing much happened in the market for a good few years. You had those who'd bought just before the crash stuck with negative equity, often in ghost estates or poorly completed apartment buildings, in homes that were intended as a first step on the ladder not a long-term investment. Those coming behind them were stuck renting or living with parents.
Things began to pick up.
Suddenly the renters could begin to look at buying again, and some people began to consider selling.
But prices hadn't fully recovered, while several years worth of FTB wanted to buy at once. Demand far outstripped supply, with viewings being crazy and houses selling almost as soon as they came on the market. friends of mine bid on over 20 houses before they were finally successful.
Now, FTB still struggle to buy. The older generation still sit on massive equity with no intention of selling. Those who bought in the run up to the crash are still in negative equity.
Nothing good happened for FTB when prices fell.
