Flipping a house involves more than finding a discount and selling at a higher price. Between acquisition and sale, every day the property sits on your books costs money. These are holding costs — and if you do not account for them early, your projected profit can vanish fast.
This guide walks through the typical holding-cost categories for a six-month flip, gives a worked example with hypothetical numbers, and points you to tools that can help you stay on track.

What are holding costs?
Holding costs are the ongoing expenses you pay while you own the property. They start the moment you take title and stop the moment you close the sale. If you are borrowing money, financing costs are part of this picture as well.
Common holding-cost categories include:
- Property taxes — charged by your city or county, usually prorated per day.
- Homeowners insurance — required by most lenders; some investors pay cash but still carry coverage.
- Utilities — electricity, water, gas, and trash service. Even if the house is vacant, these may continue.
- HOA fees — if the property is in a community with an association, dues are due monthly.
- Yard maintenance — mowing, trimming, leaf removal, or snow clearing, especially in off‑season months.
- Security and board‑up costs — protecting an vacant property from theft, vandalism, or weather damage.
- Financing costs — interest on a hard‑money loan, a line of credit, or a mortgage. Points paid at closing may also be amortized over the hold period.
Not every flip will have all of these. A property in a low‑tax suburb with no HOA will have a lighter monthly nut than a city condo with strict association rules.

Why a six‑month timeline?
Six months is a common hold period for a rehab‑focused flip. It allows time to secure financing, complete repairs, list the property, and close. Sholder periods happen when rehab runs long or the market slows; shorter flips (90 days) are possible but often require light cosmetic work only.
Your actual hold time will depend on three variables:
1. Rehab scope — a full gut renovation may take 4–5 months; a kitchen‑only flip might be 6–8 weeks.
2. Permit timeline — some cities require plan reviews, inspections, and sign‑offs that can add weeks.
3. Market conditions — a hot market may move a listed home in days; a soft market may sit for months.

Typical monthly holding‑cost breakdown
Below is a representative list of monthly costs you might see on a mid‑range flip. Use these as a starting point; your numbers will vary by location, property type, and financing.
| Category | Typical Monthly Range |
|---|---|
| Property taxes | $300 – $800 |
| Homeowners insurance | $100 – $250 |
| Utilities (vacant) | $150 – $400 |
| HOA fees (if applicable) | $0 – $300 |
| Yard maintenance | $50 – $150 |
| Security/board‑up | $0 – $100 |
| Financing interest (hard‑money 12% APR) | $1,000 – $1,500* |
\*Interest example: on a $200,000 loan at 12% APR, the monthly interest portion is roughly $2,000. If you pay points up front, those are often spread across the hold period for analysis purposes.
Total estimated monthly holding cost: approximately $1,750 – $3,550, depending on the factors above.

Worked example: a hypothetical 6‑month flip
All numbers below are hypothetical illustrations only.
- Purchase price: $250,000
- Estimated rehab budget: $45,000
- Financing: hard‑money loan at 12% APR, 2 points due at closing
- Hold period: 6 months
Step 1 – Financing cost
Loan amount: $250,000 (assuming 100% of purchase + rehab rolled into the loan for this illustration).
- Interest over 6 months at 12% APR: $250,000 × 12% × 0.5 = $15,000
- Points (2% of loan): $250,000 × 2% = $5,000 (treated as interest for holding‑cost analysis)
Total financing cost: $20,000
Step 2 – Monthly operating costs (assumed averages)
- Property taxes: $500/month × 6 = $3,000
- Homeowners insurance: $150/month × 6 = $900
- Utilities: $250/month × 6 = $1,500
- HOA fees: $0 (none applicable)
- Yard maintenance: $100/month × 6 = $600
- Security/board‑up: $0 (assumed secure site)
Total operating holding cost: $6,000
Step 3 – Total holding costs
Financing + operating = $20,000 + $6,000 = $26,000
If the property sells for $350,000 and total acquisition + rehab cost is $295,000 (purchase + rehab budget), the gross profit before holding costs is $55,000. Subtract $26,000 in holding costs, and the net profit estimate is $29,000 — before selling costs, commissions, and taxes.
This example shows why nailing down your hold time and monthly nut early matters. A one‑month extension adds roughly $4,350 in this scenario (financing prorated + operating).

Repair / rehab cost estimating
Holding costs and rehab budgets are linked because a delayed renovation stretches the hold period and adds financing interest. To keep the six‑month timeline realistic:
- Get at least three contractor bids before signing any scope of work.
- Build a 10–15% contingency into your rehab budget for unexpected issues (mold, structural, permit corrections).
- Schedule a mid‑project walk‑through at the 50% completion mark to catch delays early.
- Order long‑lead items (windows, fixtures, cabinets) early so they arrive when the crew is ready.

ARV and the 70% rule
After you know your holding costs, the next step is determining what you can pay for the property. The 70% rule is a quick filter many flippers use:
> Maximum purchase price = (After‑Repair Value × 70%) – Total rehab costs
For example, if the ARV (after‑repair value) is $350,000 and rehab is estimated at $45,000:
- 70% of ARV = $245,000
- Maximum purchase price = $245,000 – $45,000 = $200,000
This leaves room for closing costs, holding costs, and your desired profit. If your holding costs turn out higher than expected, you may need to adjust the purchase price down or look for a property with a lower ARV.

Permits and local rules
Every municipality has its own permit process. Some require separate permits for electrical, plumbing, and structural work. Others have a single “over‑the‑counter” permit for cosmetic updates. Delays in permitting are a common cause of hold‑period creep.
Before you buy:
- Call the local building department and ask typical turnaround times for the work you plan.
- Verify whether the property has all closed‑out permits from previous owners. Missing permits can halt a sale or require costly retroactive filings.
- Check zoning rules if you plan to change the property’s use (e.g., adding a second unit or converting a garage).

Taxes on flip profits
When you sell a flipped property, the gain is generally taxed as ordinary business income, not long‑term capital gains, unless you qualify for a like‑kind exchange (which is rare after the 2017 tax law changes). Set aside a portion of your projected profit for federal and state taxes. A common rule of thumb is to reserve 25–30% of net profit for taxes, but you should consult a tax professional for your specific situation.

FAQ
Q: What are the most common holding‑cost surprises?
A: Permit delays, extended vacancy, and under‑estimating financing interest. Always build a buffer into your budget.
Q: Do I pay property taxes if the house is vacant?
A: Yes. Taxes are based on ownership, not occupancy. Some jurisdictions offer exemptions for certain properties, but most will bill the owner regardless.
Q: Can I roll holding costs into the loan?
A: Some hard‑money lenders allow you to finance purchase + rehab + a reserve for holding costs. Ask your lender what options are available.
Q: How do I track holding costs during the flip?
A: Set up a simple spreadsheet with columns for date, category, and amount. Update it weekly so you see trends and can adjust your timeline if costs creep up.
Q: What if my flip takes longer than six months?
A: Extend your projections accordingly. Every additional month adds roughly the monthly holding‑cost total you calculated. Re‑run your numbers before committing to another month of financing.
Q: Are holding costs tax‑deductible?
A: Yes. Holding costs are generally deductible against your flip profit when you file your tax return. Keep receipts and a log of all expenses.
Q: Should I include HOA fees in my holding‑cost calc?
A: Only if the property you are flipping has an HOA. If you are unsure, call the management company and ask for the current dues and any special assessments.
Q: What’s the difference between holding costs and closing costs?
A: Holding costs are ongoing expenses while you own the property. Closing costs are one‑time fees paid at purchase and sale (title insurance, recording fees, attorney fees, etc.).
