Holding Costs
Holding costs are the ongoing monthly expenses during the period you own a property but are not yet receiving full rental income. For fix-and-flip investors, this means every month from purchase through closing on the sale. For BRRRR investors, it covers the renovation and lease-up period before the refinance.
Holding costs are the silent killer of flip profit. They accumulate every single month whether work is progressing or not.
What holding costs include
| Cost item | Typical monthly range | Notes |
|---|---|---|
| Property taxes | $150–$400 | 1/12 of annual tax bill |
| Insurance (vacant or builder's risk) | $80–$150 | Higher than standard landlord policy |
| Utilities (heat, electric, water) | $100–$300 | Required during renovation |
| HOA fees | $0–$500 | If applicable |
| Loan interest (hard money / bridge) | $800–$2,500 | The largest single item for leveraged deals |
| Loan origination (amortized) | $100–$400 | Points paid at closing spread over the hold |
| Security / property monitoring | $0–$100 | Vacant property risk |
| Typical monthly total | $1,200–$3,800 | Depends heavily on financing |
The formula
The hold period starts at closing on purchase and ends at closing on sale (for a flip) or on the refinance date (for BRRRR).
Worked example
A fix-and-flip property, 7-month total hold:
| Cost item | Monthly cost | 7-month total |
|---|---|---|
| Property taxes | $175 | $1,225 |
| Vacant property insurance | $110 | $770 |
| Utilities | $150 | $1,050 |
| Hard money interest ($160,000 loan @ 10%) | $1,333 | $9,331 |
| Hard money origination (2 pts amortized) | $381 | $2,667 |
| Monthly total | $2,149 | $15,043 |
Compare to a naive estimate: "it will probably cost $500/month to hold." At $2,149/month for 7 months, that is a $15,043 difference from a $3,500 naive estimate. That gap is the difference between a 15% profit margin and an 8% one.
How hold time affects profit
Using a $290,000 ARV deal with $45,000 rehab and $160,000 acquisition:
| Hold period | Monthly holding cost | Total holding cost | Estimated profit |
|---|---|---|---|
| 5 months | $2,149 | $10,745 | ~$23,000 |
| 7 months (planned) | $2,149 | $15,043 | ~$19,000 |
| 9 months (+2 overrun) | $2,149 | $19,341 | ~$15,000 |
| 12 months (worst case) | $2,149 | $25,788 | ~$8,000 |
Every extra month on a hard money loan costs $1,300–$2,500. Delays are expensive. This is why experienced flippers are obsessive about contractor timelines and permit turnaround.
Holding costs for BRRRR vs. flip
| Stage | BRRRR | Fix-and-flip |
|---|---|---|
| Purchase to rent-ready | Hard money, carrying costs — same as flip | Same |
| Lease-up period | Insurance, taxes, utilities — no income yet | N/A (already selling) |
| Refinance delay | Ongoing hold costs if appraisal takes time | N/A |
| Post-refinance | Long-term loan replaces hard money; costs drop | Property sold |
For BRRRR, holding costs end when you refinance into a permanent loan. For a flip, they end when you close on the sale. Both timelines are critical to model accurately.
Hard money interest is the biggest variable
| Loan type | Typical rate | Monthly interest on $150,000 |
|---|---|---|
| Hard money | 10–13% | $1,250–$1,625 |
| Bridge loan | 8–10% | $1,000–$1,250 |
| Conventional investment loan | 6.5–8% | $813–$1,000 |
| Cash purchase | 0% | $0 — but opportunity cost applies |
Financing type drives holding costs more than any other single factor. Experienced flippers either use cash (eliminating interest) or have established lender relationships with favorable hard money terms.
Common mistakes
1. Forgetting to model holding costs at all. Some first-time flip budgets include only acquisition + rehab costs and assume holding costs are negligible. At $2,000/month for 7 months, they are not.
2. Using the loan balance × rate instead of the actual interest schedule. If the loan includes interest reserves or is structured as interest-only (common for hard money), calculate actual monthly interest payments, not a rough estimate.
3. Not modeling a schedule overrun scenario. Always model what happens if the project takes 2–3 months longer than planned. Holding costs + market softening over a 12-month project can eliminate most of the projected profit.
4. Excluding loan origination fees from holding cost. Origination points (typically 1–3% of the loan) are paid upfront but represent a real cost of the deal. Amortize them over the expected hold period in your pro forma.
Frequently asked questions
What is the biggest holding cost most beginners miss? Hard money or bridge loan interest. Beginners often estimate holding costs by thinking about taxes and insurance ($300–$500/month) and forget that a $160,000 hard money loan at 12% interest costs $1,600/month — five times more than those other items combined.
Do I have holding costs if I buy with cash? Yes, but different ones. You eliminate interest costs, but still pay taxes, insurance, and utilities. You also face an opportunity cost — that cash invested elsewhere could be earning a return.
At what point do holding costs stop? For a flip: the day of closing on the sale. For a BRRRR: the day you close on the refinance and move into a permanent loan. Holding costs do not stop when renovations are complete — they continue through the sale or refinance process.
Should I include holding costs in my rehab budget or as a separate line? Keep them separate. Rehab costs are for the construction scope. Holding costs are for the carry. Mixing them obscures both numbers and makes it harder to diagnose where a deal went wrong.
Holding cost estimates are illustrative and vary by financing type, market, and timeline. Always model your specific loan terms and expected timeline. This is not investment advice.
