Spain's Nov 29 elections: housing platforms compared

Housing platforms for Spain’s general election on November 29, 2026, are being evaluated against a ten-point checklist finalized on July 27, 2026, before any party published theirs. The initial hypothesis is that most proposals will focus on subsidies, guarantees, and bans—measures affecting existing stock rather than removing barriers to new construction.

The criteria are fixed. Ten measures, four blocks, defined in late June 2026 and published together on July 27. No wording has changed since. Any updates go to a public amendment log with dates and reasons. This same standard applies to all parties running in the Nov 29 election, and retrospectively to 2023 platforms, which now have three years of implementation results.

The election was called by Royal Decree 806/2026 of October 5, dissolving parliament. Candidate lists come from those proclaimed in the Official Gazette (BOE) on November 3. Parties are analyzed in order of platform publication, not size or ideology. A disclaimer: this is not a voting recommendation. It assesses housing policy only, not parties or voters. A platform may score well here but poorly elsewhere, or vice versa.

## Downstream vs upstream: two blocks defining housing policy

This distinction is the method’s backbone. Downstream measures affect existing housing stock and who pays or receives benefits: purchase subsidies, rental aid, guarantees, tax deductions, income caps, lease extensions, buyer restrictions. These can relieve pressure, sometimes significantly, and mobilize unused homes. But alone they don’t remove barriers to adding supply. When supply doesn’t respond, subsidies often end up inflating prices.

Upstream measures address why supply fails to respond: land held idle because waiting costs nothing; value gains from rezoning not returning to the public; planning and permits stuck in delays; credit and tax regimes favoring buying existing homes over building new ones. The ten-point framework targets these root causes.

One principle unites the ten measures: none impose price controls by decree, nor do they simply liberalize land. All change incentives for actors who benefit from inaction. Another principle cuts across: a home counts as solving the deficit only if it adds what’s missing in type, tenure, and price—not just by existing or changing hands.

## The ten measures, block by block

Block one penalizes land hoarding: an annual tax on serviced residential land without buildings; converting property tax (IBI) into a land-value tax; real penalties for vacant homes at market value. Block two returns publicly created value to the public: capturing uplift from effective rezoning, homogeneous and traceable; using public land via surface rights instead of selling it.

Block three removes blocking power from captured actors: binding maximum deadlines with simultaneous reports and automatic substitution; ensuring compliance suffices, with a regulated right to build under clear rules. Block four addresses credit and tax regimes for those profiting from scarcity: credit for retention, not just sale; tax privileges earned by building; making moving cheaper than expanding portfolios.

Each proposal is tested against these ten. Three questions: which measure does it align with? Which lock does it open? Which remains untouched? Proposals fall into three columns: matching a measure, contradicting one, or addressing something outside the framework. Matches are distinguished as complete or partial, noting missing mechanism parts. Shortening deadlines without enforcement points to measure six but doesn’t fulfill it. Silence on a measure isn’t counted as opposition.

## Reading platforms without rally rhetoric contaminating assessment

Only written platform text counts, with page references. Statements from rallies, interviews, or social media are marked separately as declarations, since only text can be verified against text. Each proposal gets three additional checks: does it increase stock, mobilize existing homes, or redistribute access—or several? Who captures income if applied? Who has authority to implement it, and what specific instrument does the party commit to? National platforms can promise basic laws or conditional funding, but cannot order municipal procedures.

The framework doesn’t assume ten measures exhaust solutions. If a platform proposes a different mechanism solving a real barrier, it’s assessed on its merits even if it doesn’t fit. If it reveals gaps in the framework, those gaps go to the amendment log. The standard is identical for all.

## The testable prediction: majority owners, similar menus

With over seven in ten households owning their home—**73.3%** per INE’s 2025 Living Conditions Survey—the politically easiest measures avoid lowering prices of already-owned assets. These are households, not just voters, creating political incentives pushing toward predictable outcomes: ideologically distinct parties offering similar menus. More demand-side aid, more buyer restrictions, some liberalization without value capture, little on idle land.

This is a prediction and may fail. If platforms disprove it, the final report will show it using the same standard. Comparison with 2023 platforms, now with three years of implementation, is the first stress test: promises made, actions taken, outcomes achieved, party by party and where each governed.

Timing dictates process. 2026 platforms will be assessed alphabetically until published, then by publication date, each with links. Reading or analysis errors are corrected visibly with markers. This doesn’t replace reading full platforms or advise voting choices. It’s a tool to compare housing proposals consistently. As with any measurement, verify against original sources before concluding.
