The Subsidy Spiral
Why Government Help to Buy Schemes Always Make Housing More Expensive
When a housing market is starved of supply, offering buyers extra cash to help them purchase a home feels like throwing water on a grease fire. The intuition behind homebuyer credits and credit expansion is well-intentioned: help people bridge the gap to homeownership. But when the number of available homes remains stubbornly fixed, injecting more purchasing power into the market achieves a very different outcome. Instead of helping buyers afford homes, it simply gives every seller license to charge more.
The mechanics are straightforward. Housing markets in the United States face an estimated structural deficit of 2.8 million units. At the same time, the rate lock-in effect keeps existing inventory at historic lows, as homeowners clinging to low mortgage rates refuse to sell. When credit supply expands into this rigid, undersupplied landscape, it directly increases the collateral value of homes. Demand-side subsidies inevitably drive up prices, turning well-meaning assistance into a reliable propellant for housing inflation.
While the exact magnitude of these price increases varies depending on local market conditions and how easily developers can build, the broader consequences are stark. Rising prices rarely affect all buyers equally. First-time homebuyers are disproportionately priced out, left with no equity to leverage. Repeat buyers, by contrast, can easily roll the proceeds from selling their own inflated properties right into the next purchase. Meanwhile, this cheap or expanded credit supply fuels housing speculation, laying the groundwork for volatile boom-and-bust cycles.
Building more homes helps cushion the blow, but even new construction struggles with a severe geographic mismatch, often appearing far away from where acute shortages actually bite. Ultimately, subsidizing demand in a market locked by low inventory and rigid supply does not solve the housing shortage. It merely finances it.
