Washington DC property tax is not a single rate on a Zillow estimate — it is a classification system administered by the Office of Tax and Revenue (OTR) that separates homestead Class 1 from rental Class 2, stacks Business Improvement District (BID) assessments on commercial frontage, and reassesses improved property toward market value after permitted rehab. Investors who underwrite DSCR holds on the seller’s old tax bill discover compressed coverage at refi when OTR catches up to the renovation.
This guide covers Class 1 vs. Class 2 investment property, BID surcharges, post-rehab reassessment timing, and DSCR tax-line modeling — not vacant Class 3/4 (see vacant property guide) and not recordation tax (see recordation guide). Hub: investment property financing Washington DC

DC property tax classes — investor view
OTR assigns every parcel a class and assessed value. The class determines the rate applied:
| Class | Description | Typical investor asset | Homestead benefit |
|---|---|---|---|
| Class 1 | Residential ≤5 units | Owner-occ rowhouse, house hack | Homestead deduction lowers effective rate |
| Class 2 | Residential rental, commercial, mixed-use | Investment rowhouse, apartment, retail base | None — full rate |
| Class 3 | Vacant property | Unoccupied stock | Elevated rate — vacant guide |
| Class 4 | Blighted property | Deteriorated vacant | Highest rate — vacant guide |
Most investment rowhouses, legal two-units, and rental condos sit in Class 2. A sponsor who house-hacks a duplex may hold Class 1 on the owner-occ portion — see house hacking DC — but the rental unit triggers Class 2 treatment on the investment share.
Class 1 homestead vs. Class 2 investment — worked comparison
Same $720,000 assessed Shaw rowhouse:
| Scenario | Class | Homestead deduction | Modeled annual tax | Monthly PITIA tax line |
|---|---|---|---|---|
| Owner-occupant (homestead) | Class 1 | Applied | ~$4,200 | $350 |
| Investment rental (no homestead) | Class 2 | None | ~$6,800 | $567 |
| Post-rehab reassessed @ $865K | Class 2 | None | ~$8,150 | $679 |
| + BID surcharge (mixed-use base) | Class 2 + BID | None | ~$9,100 | $758 |
DSCR impact: On a $622,800 loan at 8.75%, the tax line difference between stale bill ($350/mo) and post-rehab reality ($679/mo) moves DSCR by ~0.06 — enough to drop LTV from 72% to 68% on the same rent.

2026 DC property tax rates — investor table
Rates change annually — verify on OTR before closing. Model these effective planning rates for investment pro formas:
| Class | Property type | 2026 planning rate (effective) | Investor note |
|---|---|---|---|
| Class 1 | Owner-occ ≤5 units | ~$0.85 per $100 assessed | Not your hold if non-owner-occ |
| Class 2 | Residential rental | ~$0.85–$0.95 per $100 assessed | Standard investment rowhouse |
| Class 2 | Commercial / mixed-use | ~$0.85–$0.95 + BID | Retail base on H Street corridor |
| Class 3 | Vacant | ~5× Class 1 | See vacant guide |
| Class 4 | Blighted | ~10× Class 1 | See vacant guide |
Assessment ratio: OTR assesses at market value for most residential. Post-rehab jumps follow permit triggers and triennial reassessment cycle.
Business Improvement District (BID) assessments
BIDs fund street cleaning, security, and marketing through surcharges on commercial property within district boundaries. Investor-relevant BIDs:
| BID | Coverage | Typical surcharge | Asset impact |
|---|---|---|---|
| Downtown BID | Central business district | Varies by frontage | Office-to-residential conversions |
| Georgetown BID | Georgetown commercial | Premium surcharge | Mixed-use rowhouse retail base |
| H Street NE BID | H Street corridor | Moderate | Two-unit with commercial first floor |
| NoMa BID | NoMa / near Navy Yard | Moderate | Navy Yard hard money |
| Shaw Main Streets | Shaw corridor | Lower | Shaw mixed-use |
BID fees appear on the OTR bill or as a separate invoice. DSCR underwriters include them in OpEx/tax when documented.
Worked example — mixed-use Shaw two-unit with retail base
| Line | Amount |
|---|---|
| Assessed value (post-rehab) | $920,000 |
| Class 2 property tax | $7,820/yr |
| BID surcharge (commercial base) | $1,450/yr |
| Total tax + BID | $9,270/yr ($772/mo) |
| Gross rent (upper res + lower res + retail) | $7,200/mo |
| Other OpEx | $1,850/mo |
| PITIA @ 70% LTV ($644K @ 8.5%) | $4,950/mo |
| NOI after tax/BID | $4,578/mo |
| DSCR | 0.93 — fails standard band |
Same building without retail base (residential only):
| Line | Amount |
|---|---|
| Gross rent (two residential units) | $5,400/mo |
| Tax + BID | $6,820/yr ($568/mo) |
| PITIA | $4,950/mo |
| DSCR | 1.04 — clears thin band |
Mixed-use upside on commercial lending DC must model BID + higher Class 2 assessment on the commercial share.
Post-rehab reassessment — timing and triggers
OTR reassesses when:
- Building permit closed — especially additions, pop-ups, gut rehabs
- Certificate of Occupancy issued — new unit count or use change
- Triennial reassessment cycle — citywide updates
- Sale transaction — buyer inherits current assessment; may trigger review
| Event | Typical reassessment lag | Tax bill impact |
|---|---|---|
| Cosmetic flip (no permit) | Minimal | Low — but unpermitted work risks refi |
| Permitted gut rehab | 6–18 months | +15–30% tax bill common |
| Pop-up addition | 12–24 months | +25–40% on improved value |
| English basement legalization | 6–12 months | Unit count increase — higher assessment |
| Sale to new investor | Immediate at current assessment | May jump again at next cycle |
Flip implication: Sell before reassessment lands and the buyer inherits the higher bill — but price accordingly or lose contract negotiations. BRRRR implication: Model post-rehab tax in refi PITIA from day one — not the acquisition bill.
Pair with permits guide — permitted work triggers reassessment.
Worked BRRRR example — Petworth two-unit reassessment
Operator acquires $625,000 Petworth rowhouse, legalizes English basement to three-unit:
| Phase | Assessed value | Class 2 annual tax | Monthly tax line |
|---|---|---|---|
| Acquisition (seller bill) | $580,000 | $4,950 | $413 |
| Post-rehab (OTR reassessment) | $780,000 | $6,630 | $553 |
| Stressed (+15% reassessment lag) | $897,000 | $7,625 | $635 |
DSCR refi @ 72% LTV on $780,000 appraised:
| Line | Stale tax model | Post-rehab tax model |
|---|---|---|
| Gross rent (3 units) | $6,800/mo | $6,800/mo |
| Tax line | $413/mo | $635/mo |
| Insurance + maintenance | $680/mo | $680/mo |
| PITIA @ 8.75% | $4,820/mo | $4,820/mo |
| DSCR | 1.14 | 1.06 |
| Achievable LTV | 72% | 68% |

DSCR tax-line underwriting
DSCR = rent ÷ PITIA. Property tax sits inside PITIA (principal, interest, taxes, insurance):
| Pro forma mistake | Refi outcome |
|---|---|
| Using seller’s pre-rehab tax bill | DSCR overstated — fails at underwriting |
| Ignoring BID on mixed-use | OpEx understated |
| Class 1 rate on investment rental | Rate wrong — use Class 2 |
| No reassessment stress | Thin refi becomes fail at 12-month mark |
| Homestead deduction on non-owner-occ | Disallowed — full Class 2 rate |
Conservative modeling:
- Estimate post-rehab assessed value = appraised value × 0.90–1.00
- Apply Class 2 rate from OTR table
- Add BID if commercial frontage
- Stress +10–15% for lag between CO and bill
- Include in PITIA — not separate OpEx line (lender preference varies; total PITIA is what matters)

Flip pro forma — tax carry on hold
Flippers hold 6–14 months on hard money at 8.99%–13.5%. Property tax during hold:
| Hold period | Acquisition tax/mo | Post-rehab tax/mo (if reassessment lands) |
|---|---|---|
| 6 months | $413 | $413 (usually unchanged) |
| 12 months | $413 | $553 (reassessment may hit) |
| 18 months | $413 | $635 (pop-up/addition cases) |
Most flips sell before reassessment — but long HPRB delays (see HPRB guide) extend hold into reassessment territory.
Worked flip — Brookland rowhouse:
| Line | Amount |
|---|---|
| Purchase | $545,000 |
| Acquisition transfer tax | See recordation guide |
| Rehab | $135,000 |
| Property tax carry (8 mo @ $480/mo) | $3,840 |
| Hard money IO (8 mo @ 11%) | $42,000 |
| ARV sale | $745,000 |
| Exit transfer tax | $16,390 |
| Net margin | Tax carry is ~5% of gross spread — material on thin deals |

Homestead, house hack, and entity ownership
| Structure | Tax class treatment | Investor note |
|---|---|---|
| Owner-occ duplex (house hack) | Class 1 with homestead on owner unit | House hacking DC |
| LLC-owned rental rowhouse | Class 2 — no homestead | Standard investment |
| Trust-held investment | Class 2 | Verify with counsel |
| Mixed owner-occ + rental | Split treatment possible | Counsel required |
Homestead fraud — claiming Class 1 on non-owner-occ investment — triggers OTR penalties and kills refi.
Cross-border comparison
| Market | Investment property tax | Reassessment trigger |

| DC Class 2 | ~$0.85–$0.95 per $100 | Permit + triennial |
| Montgomery County MD | County rate + municipal | Different stack — MoCo vs DC |
| Arlington VA | Virginia rate | Different reassessment cycle |
| Alexandria VA | City rate | Lower transfer tax, different property tax |
