DC Rowhouse Condo Conversion Deal Math 2026
By Jason Taken · Principal, Jaken Finance Group
Washington DC rowhouse-to-condo conversion deal math — acquisition, TOPA, rehab, conversion fees, sell-out vs DSCR exit. Worked Capitol Hill example.
A Washington DC rowhouse-to-condo conversion is four products in one deal: bridge acquisition, renovation, regulatory subdivision, and retail sell-out (or DSCR hold on unsold units). Sponsors who treat it as a cosmetic flip underestimate TOPA friction, HP review, conversion fees, and staggered closings — each line item compresses margin if omitted from the pro forma.
This post walks complete deal math on a worked Capitol Hill file. Pair it with condo conversion financing Washington DC and TOPA compliance guide before you bind terms.
Why DC rowhouse conversions attract capital
DC’s housing stock includes thousands of 4–8 unit rowhouses in Capitol Hill, Columbia Heights, Petworth, and Shaw — assets too large for single-family flip economics but subdividable into condo units that sell to owner-occupants at premium per-square-foot pricing.
The strategy works when:
- Acquisition is vacant or TOPA-navigable with counsel budgeted
- Rehab scope achieves separate unit metering and HP-compliant facade
- Sell-out comps support $450K–$550K per unit on 750–900 sf product
- Bridge capital covers 14–20 month timeline with interest reserve

The asset: 4-unit Capitol Hill rowhouse
| Input | Value |
|---|---|
| Location | Capitol Hill — historic district, HP review on facade |
| Configuration | 4 units (2 per floor), vacant at acquisition |
| Condition | Estate sale, dated systems, cosmetic-plus-structural scope |
| Purchase price | $1,048,000 |
| Acquisition friction (recordation ~2.2%) | ~$23,000 |
| Close timeline | 12 days (hard money) |
Vacant acquisition avoids TOPA — saves 60–120 days vs occupied file. If upper tenant existed, add $5K counsel + 90 days minimum under Rental Housing Act compliance.
Rehab and conversion scope
Unit-level rehab
| Line item | Cost |
|---|---|
| Electrical panel + rewiring (4 units) | $68,000 |
| Plumbing (kitchens/baths, 4 units) | $92,000 |
| HVAC (4 mini-split systems) | $44,000 |
| Kitchens and baths (mid-spec) | $96,000 |
| Common area + facade (HP-compliant) | $38,000 |
| Subtotal rehab | $338,000 |
Conversion and regulatory
| Line item | Cost |
|---|---|
| DC conversion fee | $11,200 |
| Survey + plat | $8,500 |
| Condo documents + legal | $22,000 |
| HP submission + review | $9,800 |
| Subtotal conversion | $51,500 |
Total project cost: $1,437,500 (purchase + friction + rehab + conversion)
Scope must achieve separate utilities, fire separation, and condo plat compliance — not just cosmetic refresh. Draw schedule ties to DOB milestones, not arbitrary monthly releases.
Financing structure
| Layer | Amount | Terms |
|---|---|---|
| Bridge / hard money | $1,412,000 (100% LTC) | 10.75% IO · 18-month term |
| Sponsor equity | $0 on qualified 100% file | Reserves for carry + friction |
| Interest carry (16 months) | ~$165,000 | IO on average outstanding balance |
| Extension contingency | $8,500 fee | Month 17 if sell-out slips |
Qualified sponsors on experienced files access 100% LTC when sell-out comps, scope, and timeline are documented at submission. Carry at 8.99%–13.5% IO is the margin variable — every month past month 16 costs roughly $10K on outstanding bridge balance.
Product: bridge loans Washington DC.
Sell-out pro forma
| Unit | Size | Target price | Buyer profile |
|---|---|---|---|
| Unit 1 (ground front) | 780 sf 1BR | $495,000 | Owner-occupant |
| Unit 2 (ground rear) | 720 sf 1BR | $475,000 | Investor / DSCR |
| Unit 3 (upper front) | 850 sf 2BR | $525,000 | Owner-occupant |
| Unit 4 (upper rear) | 800 sf 2BR | $510,000 | Owner-occupant |
Gross sell-out: $2,005,000
Price per square foot runs $650–$720 — verify against recent Capitol Hill condo solds, not rowhouse rental comps.
Profit waterfall
| Line item | Amount |
|---|---|
| Gross sell-out | $2,005,000 |
| Less: loan payoff | ($1,412,000) |
| Less: interest carry | ($165,000) |
| Less: selling costs (5.5%) | ($110,275) |
| Less: recordation on 4 sales (~1.1% avg) | ($22,055) |
| Net profit | ~$557,670 |
Margin compresses if one unit sells 90 days late — carry adds ~$10K/month on outstanding bridge balance. Stagger listings starting month 11; do not wait for 100% completion to market unit one.
Alternative exit: hybrid sell + DSCR hold
When sell-out market softens mid-project, hybrid exit preserves capital:
- Sell Units 1 and 3 (owner-occupant premium): $1,020,000
- Pay down bridge to ~$130,000
- DSCR hold Units 2 and 4 at $1,950/mo each
| Metric | Value |
|---|---|
| Gross rent (2 units) | $3,900/mo |
| Combined value | ~$985,000 |
| DSCR refi (85% LTV rate-and-term) | $837,250 @ 6.75% |
| DSCR ratio | 1.03 |
Hybrid trades immediate profit for recurring cash flow — common when interest rates compress owner-occupant buyer pool. Permanent DSCR runs 5.75%–10.5% on qualified investor files.
Sensitivity table
| Variable | Base case | Downside | Upside |
|---|---|---|---|
| Sell-out price/unit | $500K avg | $460K avg | $530K avg |
| Hold period | 16 months | 20 months | 14 months |
| Rehab overrun | $0 | +$45K | -$20K (value eng.) |
| Net profit | $558K | $383K | $698K |
Downside case still clears strong return — but only if TOPA and HP timeline stay inside 20-month envelope. Occupied acquisition without counsel budget turns downside into loss.
Strategy comparison on this asset
| Strategy | Outcome | Product |
|---|---|---|
| Condo conversion sell-out | ~$558K profit on 100% LTC | Bridge DC |
| Single-family flip | N/A — 4-unit non-conforming | — |
| BRRRR hold all 4 as rentals | $3,900/mo gross | DSCR DC |
| New construction pop-up | Different asset class | New construction DC |
Timeline — month by month
| Month | Milestone |
|---|---|
| 0 | Close acquisition |
| 1–2 | Permits submitted (HP + DOB) |
| 3–8 | Rehab draws |
| 9–10 | Conversion docs + fee payment |
| 11 | First unit listed |
| 11–16 | Unit closings (staggered) |
| 16 | Bridge retired |
Build 60-day slippage buffer into interest reserve — HP review and DOB backlog are structural, not exceptional.
Red flags before LOI
- Occupied building without TOPA counsel and timeline budget
- Facade scope that ignores HP material requirements
- Sell-out comps from Maryland suburbs
- Single exit (sell-out only) with no DSCR fallback
- Bridge term under 15 months on historic district file
Columbia Heights and Petworth — basis comparison
Capitol Hill commands premium sell-out but higher acquisition basis. Comparable 4-unit files in Columbia Heights or Petworth often run:
| Input | Capitol Hill | Columbia Heights |
|---|---|---|
| Purchase | $1,048,000 | $820,000–$920,000 |
| Rehab + conversion | $389,500 | $360,000–$410,000 |
| Avg unit price | $500K+ | $420K–$480K |
| Gross sell-out | $2,005,000 | $1,720,000–$1,880,000 |
| Net profit (base) | ~$558K | ~$380K–$450K |
Lower basis reduces carry exposure on the same timeline — attractive when sell-out velocity matters more than per-unit premium. Tradeoff: HP review still applies in historic districts; non-historic Petworth may shorten facade scope 30–45 days.
TOPA and occupied acquisition — budget template
If you cannot buy vacant, model occupied acquisition explicitly:
| TOPA line item | Cost / time |
|---|---|
| Tenant counsel | $3,500–$7,500 |
| TOPA notice period | 45–120 days |
| Relocation / buyout (if negotiated) | $5,000–$15,000 per unit |
| Extended carry (3 mo @ 10.75%) | ~$30,000 |
| Total TOPA friction | $50K–$90K + 3–4 months |
Occupied files can still profit — but net margin drops 10%–15% vs vacant on identical sell-out. Price the acquisition discount accordingly or pass.
Marketing stagger strategy
Do not wait for certificate of occupancy on all four units before listing:
- Month 9–10: List unit with earliest CO — often ground front with separate entry
- Month 11: List second unit; first under contract
- Month 12–16: Close staggered; adjust pricing on remaining inventory based on absorption
Each month of unsold inventory costs ~$10K carry on this file size — pricing discipline at month 13 beats aspirational ask at month 16.
Bottom line
DC rowhouse condo conversions reward sponsors who model regulatory friction, staggered sell-out, and carry at 8.99%–13.5% IO as core deal costs — not surprises. The Capitol Hill worked example clears ~$558K net on 100% LTC when vacant acquisition, HP-compliant scope, and hybrid exit option stay in the pro forma from day one.

Permanent 5.75%–10.5% DSCR sizes on executed lease rent with investor tax and insurance in NOI — not seller bills or STR pro forma. DC deals need local sold comps — not statewide templates.
