The Rehab Timeline

Rehab timelines are the bridge between purchase and rental stabilization. Delays cascade into missed draws, hard money interest overages, and refinance timing creep.

Key takeaways

• Realistic single-family rehabs run 60–120 days; complex projects, severe distress, or permit delays extend to 120–180 days.
• Critical path activities (foundation repairs, electrical/plumbing rough-in, roof) are longest-lead items; delays in these back up the entire schedule.
• Permit timelines vary by jurisdiction; some cities turn around permits in 5–10 days, others take 30+ days. This directly extends the project.
• Seasonal factors (weather delays, contractor availability, supply chain) affect timelines; winter rehabs in northern markets may run 20–30% longer than spring rehabs.
• Weekly progress meetings, dependency mapping, and contingency buffers (15–20% over estimated duration) prevent timeline surprises.

The baseline timeline: 120-day rehab

A standard single-family home rehab in favorable conditions takes approximately 120 days (4 months) from closing to certificate of occupancy. This assumes:

• Property is unoccupied (no tenant displacement delays).
• Major systems (roof, HVAC, electrical, plumbing) are beyond end-of-life and require full replacement.
• No hidden major damage (foundation, mold, asbestos).
• Local permits are routine and issue within 10–15 days.
• General contractor is experienced and available.
• Trades (electrician, plumber, roofer) coordinate and maintain schedule.
• Weather is normal (no extended rain delays).

The 120-day timeline breaks down roughly as:

Week 1–2 (closing to permitting):

• Close on property (1–3 days).
• Initial inspection and scope finalization (3–5 days).
• Prepare permit applications (3–5 days).
• Submit permits (day 7–10).

Week 2–3 (permitting):

• Permit review and issuance (5–15 days depending on jurisdiction).
• Plan for simultaneous demolition while permits process.

Week 3–6 (demolition and site prep):

• Dumpster rental and waste removal (ongoing).
• Interior demolition (flooring, trim, fixtures) (1–2 weeks).
• Exterior demolition (siding, roofing) if needed (2–3 weeks).
• Foundation/structural repairs if minor (concurrent with demolition).

Week 6–10 (rough-in trades):

• Electrical rough-in (wiring, panel, sub-panel) (2–3 weeks, often concurrent with framing/structural work).
• Plumbing rough-in (supply lines, drain lines) (2–3 weeks).
• HVAC rough-in (ductwork, furnace mounting, condenser) (1–2 weeks).
• First rough-in inspection by municipal inspector (end of week 9).

Week 10–14 (roof, exterior, drywall):

• Roof replacement (3–7 days for shingles; 1–2 weeks for tile or metal).
• Exterior siding/cladding (1–3 weeks if extensive).
• Drywall installation and taping (1–2 weeks).
• Second rough-in inspection by municipal inspector (pass for finish work).

Week 14–18 (finishes):

• Kitchen installation (cabinets, countertop, appliances) (1–2 weeks).
• Bathroom tile and fixtures (1–2 weeks).
• Interior flooring (1–2 weeks, often concurrent with kitchen/bath).
• Paint (interior and exterior) (1–2 weeks).

Week 18–20 (final systems and certificate of occupancy):

• Electrical final inspection and trim-out.
• Plumbing final inspection.
• HVAC final inspection and startup.
• Final walk-through by municipal inspector.
• Certificate of occupancy issuance (1–3 days post-final inspection).

Total: 120–140 days (17–20 weeks).

Shortening the timeline: 60–90 days

Aggressive rehabs can shorten to 60–90 days with favorable conditions:

• Property has mostly cosmetic issues (paint, flooring, fixtures, appliances).
• Structural systems (foundation, roof, electrical, plumbing) are sound or require only minor upgrades.
• Permits are pre-expedited or not required for cosmetic work.
• General contractor has a dedicated crew available (not juggling other projects).
• Trades work in tight overlaps: framers and electricians on-site simultaneously.

A 60-day timeline assumes:

• Weeks 1–2: Close and permitting.
• Weeks 2–3: Cosmetic demolition (flooring, fixtures, trim).
• Weeks 3–4: Paint (interior and exterior), flooring, appliances.
• Weeks 4–5: Kitchen and bathroom finishes (if any).
• Weeks 5–6: Final systems checks and CO.

Aggressive timelines require experienced GCs, pre-scheduled trades, and properties without hidden issues. The risk is that an unexpected structural problem discovered during demolition (rotten subfloor, electrical panel failure) cascades into a 2–4 week delay.

Extending the timeline: 120–180 days

Conservative or complex rehabs run 120–180 days:

• Property has severe distress (extensive structural damage, mold, unpermitted electrical work).
• Permits are complex or require expedited processing (zoning variances, historic district approval).
• Critical systems are oversized or require special permitting (new electrical panel, new plumbing stack).
• Weather delays (winter in northern climates, hurricane season in Gulf states).
• Contractor availability (specialized trades like foundation work or structural engineers).
• Utility coordination (gas line rerouting, water meter upgrades, electrical service upgrade).

A 180-day timeline allows:

• Weeks 1–4: Permitting and structural engineering (for foundation/framing repairs).
• Weeks 4–8: Structural repairs (foundation, framing, severe roof damage).
• Weeks 8–12: Electrical and plumbing rough-in (expanded scope).
• Weeks 12–16: Roof, exterior, drywall (longer due to specialized contractors or material lead times).
• Weeks 16–22: Finishes (kitchen, bathroom, flooring, paint).
• Weeks 22–26: Final systems, inspections, CO (extended due to complexity).

Critical path and bottleneck identification

The critical path is the longest sequence of dependent activities. Any delay on the critical path delays the entire project. Non-critical activities (called "float" or "slack") have flexibility.

For a typical BRRRR rehab, the critical path is often:

Permits → Structural work → Rough-in trades → Roof/drywall → Finishes → Final inspections → CO.

Within this path, the longest-lead items are typically:

1. Permits (5–30 days): Jurisdiction-dependent. If your city requires expedited structural engineering, permitting alone can be 30–45 days.
2. Structural work (10–60 days): Foundation repairs, major framing, sistering joists. This is rarely on the critical path if mild, but foundation work can stretch weeks.
3. Roof (7–14 days): Weather-dependent. Rainy season adds duration.
4. Electrical rough-in (7–14 days): Often concurrent with framing, but if panel upgrade or service upgrade is needed, specialized contractors may have lead times.
5. Plumbing rough-in (7–14 days): Can overlap with electrical; rarely the critical path unless the property requires significant rerouting.

Activities not on the critical path (e.g., kitchen finishes if they don't delay final systems) have flexibility. If the kitchen is delayed by one week but painting and electrical trim-out continue, the schedule absorbs it. But if rough electrical is not done by the time drywall is scheduled, drywall is delayed.

Identify the critical path early: work with the GC to map dependencies and sequence trades. If permitting is slow, expedite the permit applications or design work while the property closes. If roof lead time is long, order materials pre-close.

Permit and inspection timelines

Permits are the often-overlooked lever on timeline. A city that issues permits in 5 days is dramatically faster than one taking 30 days.

Research your target market's permit timelines before buying:

• Contact the city building department: "How long does a residential rehab permit take?"
• Ask your general contractor: "What cities are slow? Which are fast?"
• Network with other BRRRR investors: "How long did permits take for your last deal?"

Some jurisdictions (Florida, Texas, Arizona) are known for quick permits (5–10 days). Others (California, New York, Massachusetts) can take 30–60 days. Some require architectural drawings for every electrical change; others allow GC-stamped single-page permit requests.

Once permits are issued, inspections are scheduled. Rough inspections (framing, electrical rough-in, plumbing rough-in) typically happen within 1–3 days of request. Final inspection happens when the GC certifies all work is complete; some jurisdictions issue CO same-day, others require 1–5 days.

Build the permit timeline into your schedule. If your city takes 20 days to issue permits, your project doesn't start demolition until day 20. If you budget 120 days start-to-finish, you need 140 days from closing to CO (120 days construction + 20 days permitting).

Weather and seasonal factors

Weather significantly impacts outdoor work: roofing, siding, exterior painting, and foundation work.

Northern climates (winter is October–April):

• Winter weather delays: rain, snow, cold temperatures slow roofers, exterior work, and concrete curing.
• Winter projects typically run 20–30% longer than summer projects.
• Winter material delivery can be delayed (cement trucks don't pour in freezing conditions).
• Solution: Plan winter projects with 30% timeline buffer, or schedule for spring/summer.

Hot/humid climates (summer is May–September):

• Summer heat delays roofing (roofers avoid extreme heat; shingles don't adhere in extreme heat).
• Hurricane season (June–November for Gulf Coast) creates material shortages and contractor unavailability.
• Concrete curing is faster in heat (advantage).
• Solution: Plan roofing for cooler months; schedule hurricane-prone properties for winter.

Rainy climates (Pacific Northwest, Southeast):

• Rain delays roofing, exterior work, and foundation curing.
• Rainy season projects assume 2–4 extra weeks for weather delays.
• Solution: Plan projects pre-season or accept timeline extension.

Successful BRRRR investors in seasonal markets plan acquisitions to align with favorable seasons. A Phoenix investor closes deals November–January (avoid summer heat). A Seattle investor closes April–September (avoid winter rain).

Contractor coordination and scheduling

The GC is responsible for scheduling trades and managing the critical path. A skilled GC will overlap trades (electrician and plumber on-site simultaneously), sequence to avoid re-work, and communicate delays immediately.

Establish weekly progress meetings:

• GC, key trades (electrician, plumber, roofer), and you (or your project manager).
• Review completed work, inspect quality, confirm next week's schedule.
• Address issues (material shortages, scope questions, permitting blockers).
• Confirm hard money draw schedule and lender inspection dates.

Weekly meetings prevent surprises. If the roofer's crew is suddenly unavailable and needs to reschedule two weeks out, you know immediately and can adjust the critical path (perhaps accelerate drywall and finishes).

Poor GC communication is the #1 cause of timeline blowouts. A GC who doesn't communicate delays until they are critical, or who doesn't coordinate trades, stretches a 120-day project to 150+ days.

Interview GCs about their scheduling practices: Do they use project management software? What is their typical communication cadence? How do they handle trade delays?

Contingency and buffers

Always add a time buffer. If your hard-cost estimate is 120 days, your actual timeline is 140 days (120 + 15% buffer). This absorbs weather delays, permit hold-ups, trade availability, and minor scope adjustments.

A 120-day project with zero buffer is brittle; any surprise cascades into hard money interest overages and refinance delays. A 120-day project with a 20-day buffer (140-day actual) provides realistic cushion.

Some investors structure hard money loans with explicitly longer terms to accommodate delays. Instead of a 6-month (180-day) term ending day 180, they request a 7-month (210-day) term, accepting slightly higher carrying costs in exchange for lower refinance timeline pressure.

Timeline tracking and early warning systems

Create a simple timeline chart: major milestones (permits issued, framing complete, rough-in inspection, CO) with planned vs. actual completion dates. Update weekly.

If actual dates begin to slip, investigate immediately:

• Is the slip structural (foundation work taking longer than estimated)?
• Is the slip contractor-related (the roofer pushed back two weeks)?
• Is the slip permitting-related (the city delayed inspection)?

Early identification allows course correction: hire additional labor, add a second shift, expedite material delivery, or renegotiate the refinance date with the lender.

Hard money timeline coordination

Communicate the rehab timeline to your hard money lender upfront. If your timeline is 140 days (closing to CO), the lender's interest-only period should last 6 months (180 days) minimum, providing 40 days of buffer before the refinance must close.

Some hard money lenders offer "extension clauses" allowing one or two 30-day extensions if the project is delayed. This is valuable insurance; confirm extension terms and costs before signing.

The timeline and budget are interdependent; the final major decision is who executes the rehab. Hiring a general contractor trades time and attention for higher cost; self-managing trades cost for time and direct involvement. The next article covers this trade-off and the decision framework.
