Holding Costs (Carrying Costs)
The ongoing costs of owning a property while you hold it — loan interest, taxes, insurance, utilities. On a flip, holding costs accrue every month until the sale, so a longer timeline directly erodes profit.
Holding costs — also called carrying costs — are the ongoing expenses of owning a property for the period you hold it. On a fix-and-flip, these are the costs that pile up every month from purchase until sale, whether or not the property is producing any income. Because they're time-dependent, holding costs are one of the biggest reasons a flip's timeline directly affects its profit.
What's in holding costs
- Loan interest — usually the largest, accruing monthly on the financing.
- Property taxes — prorated for the months you own it.
- Insurance — vacant/builder's-risk coverage during a rehab.
- Utilities — electric, water, gas to run the job and keep systems on.
- HOA dues, lawn care, security, and other upkeep while vacant.
These are part of a project's soft costs, and a complete rehab budget and MAO must include them.
Why holding costs make time the enemy
The defining feature of holding costs is that they accrue with time. Every extra month a flip takes — a slow rehab, a permitting delay, a property that lingers on the market — adds another month of interest, taxes, insurance, and utilities. A flip projected to take 4 months that stretches to 7 piles on three extra months of carrying costs, eroding the profit even if the hard costs stayed on budget.
A worked example
A $200,000 hard money loan at 11%, plus taxes/insurance/utilities of ~$700/month:
Loan interest ≈ 200,000 × 11% ÷ 12 ≈ $1,833/month
Other carrying ≈ $700/month
Total holding cost ≈ $2,533/month
Over a 5-month flip that's ~$12,700; stretch it to 8 months and it's ~$20,300 — a $7,600 hit to profit purely from extra time.
How holding costs shape financing decisions
- They favor speed. Minimizing the hold is the most direct way to protect flip profit — efficient rehab, fast draws, and prompt listing all reduce carrying costs.
- They inform the points-vs-rate trade-off. On a short flip, points dominate; but if a project runs long, the rate (which drives monthly interest) matters more than expected — another reason to compare total cost over the hold.
- An interest reserve covers part of them. It pre-funds the interest portion of holding costs from the loan, easing cash flow during the rehab.
Practical takeaway
Always budget holding costs for a realistic, slightly conservative timeline — not your best-case schedule — and build them into your MAO and rehab budget. Then treat speed as a profit lever: every month you shave off the hold is money kept. The 70% rule's built-in spread assumes a normal hold; blow the timeline and holding costs are often what quietly turns a projected winner into a break-even deal. Respect the clock, and carrying costs stay manageable.
Frequently asked questions
What are holding costs on a flip?
The ongoing costs of owning the property while you hold it — loan interest (usually the biggest), property taxes, insurance, utilities, and upkeep like HOA dues and lawn care. They accrue every month from purchase until sale, regardless of whether the property produces income, and are part of the project's soft costs.
How do holding costs affect flip profit?
Directly, because they're time-dependent. Every extra month the project takes adds another month of interest, taxes, insurance, and utilities. A flip that runs three months longer than planned piles on three months of carrying costs, eroding profit even if the hard costs stayed on budget. Speed protects profit.
Should I include holding costs in my maximum offer?
Yes. A proper maximum allowable offer and rehab budget must account for holding costs over a realistic, slightly conservative timeline. The 70% rule's built-in spread assumes a normal hold; if you ignore carrying costs or assume a best-case schedule, you risk overpaying and watching a longer timeline erase your margin.
