### 2025 price benchmarks (DST + Boliga)

| Region | Avg DKK/m² (apt) | Avg total (parcelhus, single-family) |
|---|---:|---:|
| **København K (centro)** | 50,000–75,000+ | 8,000,000–18,000,000+ |
| **Greater København** | 35,000–55,000 | 5,500,000–9,500,000 |
| **Frederiksberg** | 50,000–75,000 | 7,000,000–14,000,000 |
| **Aarhus** | 30,000–48,000 | 4,000,000–7,500,000 |
| **Odense** | 22,000–35,000 | 3,200,000–5,500,000 |
| **Aalborg** | 18,000–30,000 | 2,800,000–4,800,000 |
| **Smaller cities** | 14,000–22,000 | 2,200,000–4,000,000 |
| **Rural Jylland / Fyn** | 8,000–18,000 | 1,500,000–3,500,000 |
| **Sommerhuse coastal** | varies | 1,500,000–8,000,000+ |

### Compute

1. DKK/m² = price / **boligareal** (BBR-registered area)
2. **OIS sale prices** = official, post-completion
3. **Andelsbolig math**: andel pris (share value) ≠ market value; capped by association rules
4. **Energimærke** A-G: A is best; F-G near unmortgageable
5. Cross-check sold prices via Boliga + Vurderingsportalen

### Andelsbolig specific (CRITICAL)

For andelsbolig, you must check:
- **Andelskrone** (share value per square meter) — the price ceiling per association
- **Generalforsamlingsreferat** (general assembly minutes) — financial health
- **Årsregnskab** + **vedligeholdelsesplan** — backlog repairs
- **Foreningens gæld** (cooperative debt) — high debt = repair backlog risk
- **Andelsforeningens vedtægter** — what you can/can't do
- **Belåningsgrad** (ratio of debt to value) — high = restructuring risk

### Key terms

- Ejerbolig = freehold
- Andelsbolig = cooperative
- Sommerhuse = summer cottage (different zone + tax)
- BBR-meddelelse = building register notice
- Boligskat = combined property tax
- Tinglysning = registration

## Section: `--traffic`

### Sources

- **Vejdirektoratet**: `https://www.vejdirektoratet.dk/` — road agency
- **Vejman.dk** — traffic counts platform
- **Mastra (Mastrabasen)** — traffic count database, open

### Key term

**ÅDT (Årsdøgntrafik)** = AADT-equivalent.

### Verdict bands

- 🟢 < 1,500 v/d (boligvej, residential street)
- 🟡 1,500–10,000 v/d (kommunal vej, urban arterial)
- 🟠 10,000–30,000 v/d (statsvej, motortrafikvej)
- 🔴 > 30,000 v/d (motorvej, urban core E-vej)

---

## Section: `--tax`

### Annual property tax — Boligskat (MAJOR REFORM 2024)

**1 January 2024 reform** combined two old taxes into single **boligskat**:

#### Components

1. **Grundskyld** (land tax):
   - Base: 80% of grundværdi (precautionary 20% deduction)
   - Rate: **0.51%** below skattegrænse / **1.4%** above (2026)
   - Progressionsgrænse: **DKK 9,200,000 (2024 base, indexed annually under Personskattelovens §20)** (2026-05-27 verified, source: vurderingsportalen.dk; 2024 boligskat reform halved pre-reform 0.92%/3.0% rates and added a 20% precautionary deduction)
   - **Kommunale promille**: 16-26‰ varying per kommune for grundskyld
2. **Ejendomsværdiskat** (property value tax):
   - Base: 80% of ejendomsværdi (full property value, also 20% reduction)
   - Rate: **0.51%** below threshold / **1.4%** above
   - Applies to ejerbolig + sommerhus only

#### Collection (NEW since 2024)

- Both collected via **statskat** (state tax) — pulled from your **forskudsopgørelse** (preliminary tax return)
- No longer kommune-direct
- 2025 + 2026 use **preliminary 2024 valuation**; final adjustment retroactive

#### Stigningsbegrænsning (transitional cap)

- 2024-2026: cap on year-on-year increase to soften reform impact
- Phase-out by ~2030

### Transaction taxes

- **Tinglysningsafgift** (registration fee): **0.6% + DKK 1,850 flat** for property purchase (2025); **1.45% + flat** for mortgage
- **No general transfer tax** beyond tinglysning — **lowest in W. Europe**
- **Mæglersalær** (broker): typically **1.5–3%** paid by seller (negotiable)
- **Notar fees**: not mandatory in DK (advokat optional)

### Total transaction cost (buyer side)

- Resale primary residence: **~1–2.5%** of price (very low compared to W. Europe)
- Mortgage adds 1.45% tinglysning of mortgage amount

### Capital gains

- **Ejerbolig (Ejendomsavancebeskatningsloven §8 'parcelhusreglen', LBK nr 132 af 25/01/2019)**: capital gain on primary residence often **EXEMPT** if owner-occupied + plot ≤1,400 m² (or subdivision impossible per kommune); sommerhus → §8 stk. 2 (2026-05-27 verified, source [retsinformation.dk](https://www.retsinformation.dk/eli/lta/2019/132))
- **Sommerhus (sommerhusreglen)**: similar exemption if for personal use during ownership
- **Investment property**: progressive income tax up to **52.07%** (or 22% selskab if held in company)

### VAT (moms)

- 25% standard
- Real estate transactions exempt (excl. specific commercial)
- New build sale by trader: 25% moms (developer-paid)

### Future risk

- **Boligskat continues to phase in** (transitional cap)
- **Stigningsbegrænsning** ends gradually toward 2030
- **Andelsbolig taxation** debated periodically

### Long-term residential

- **Lejeloven** (Tenancy Act): tenant-protective; particularly strict in older buildings (pre-1992)

- **Andelsbolig rules**: members of housing association; specific share-purchase rules
- **Tidsbegrænsede aftaler** common
- **Indekslejekontrakt** (index-linked rent): **caps tightened** since 2022 amid inflation

  - **70 nights/year cap** København + Frederiksberg (primary residence)

## Active fiscal incentives (2025-2026)

- **Bygningspuljen**: insulation grants (up to ~DKK 50,000, est. — verify current cap at sparenergi.dk)
- **Skrotningsordning**: oil furnace replacement
- **Varmepumpepuljen**: heat pump grants

## Common listing platforms

- **Boligsiden** — biggest, most listings
- **Boliga** — sold-price specialty
- **Home.dk, EDC.dk, RealMaegler, Nybolig, DanBolig** — agency networks

## Caveats unique to DK

- **Andelsbolig** (cooperative) is a major form, especially København (~35%); you own **shares** in a housing association, not the apartment
  - Andelskrone caps share price; foreningens gæld = main risk
  - **Andelsforeningens financial health** audit critical before buying
  - **Bopælspligt** in some andelsforeninger — must live there
- **Boligskat reform 2024** combined ejendomsværdiskat + grundskyld; 2025-2026 use preliminary 2024 valuations with retroactive adjustment
- **Stigningsbegrænsning** caps tax increase impact through ~2030
- **Parcelhusreglen** (primary-residence capital gain exemption) is generous — plot ≤1,400 m² + owner-occupied
- **Sommerhus rules** distinct: own zone, max 70 nights non-resident rental
- **Airbnb caps**: 70 nights København / 30 elsewhere for primary residence
- **Storm surge stormflodsråd** insurance scheme — properties get A-D rating; D = uninsurable
- **20 Oct 2023 storm surge** = recent reference event for southern coasts
- **Bornholm radon** distinct hotspot
- **PCB in fugemasse 1950–1977** — banned but still in many older buildings
- **NemID/MitID** required for tinglysning + tax + Skat services
- **Tinglysning fully digital since 2009** — fast registration
- **Boligreguleringsloven repealed 1 July 2022** (consolidated into new Lejeloven + Lov om boligforhold); existing tenants protected via transitional rules
- **Foreign-buyer regime — Lov om erhvervelse af fast ejendom (Erhvervelsesloven)** (2026-05-27 verified, source: civilstyrelsen.dk): non-resident buyers without 5+ years prior DK residency need **Civilstyrelsens tilladelse** (permission moved Justitsmin → Civilstyrelsen 9 Jul 2018). **EU/EEA + Nordic** citizens exempt for year-round (helårsbolig). **Sommerhus**: even EU/EEA need Civilstyrelsen permission absent "special connection" (close DK family, professional/cultural/economic ties) — preserved under Edinburgh Agreement 1992 / Amsterdam Treaty Protocol No. 32 sommerhusprotokol
- **Sønderjylland German minority** — bilingual context

## Status

✅ **Fully populated** as of 2026-04-25.
**Coverage check**: pricing, traffic, tax (with 2024 boligskat reform), rental, work, risks (incl. storm surge ratings + 20 Oct 2023 reference event), mains all have primary government sources.
**Confidence**: HIGH for boligskat 2024 reform (Vurderingsportalen + Bolius confirm rates 0.51%/1.4% + 20% deduction); HIGH for tinglysning (1 unified register since 2009); HIGH for andelsbolig structure (DK-specific). MEDIUM for Boligreguleringsloven post-1 July 2022 transition specifics (rapidly changing).
