What Is Carrying Costs?
Carrying costs are the monthly "cost of ownership" for any property. For fix-and-flips, they overlap with holding costs—loan payments, property tax, insurance, utilities. For rentals, they're part of operating expenses. Higher interest rates and longer flip timelines increase carrying costs and erode profit.
Carrying costs are the ongoing expenses of owning a property—loan payments, taxes, insurance, utilities, and maintenance—whether you're rehabbing, renting, or holding for sale.
At a Glance
- What it is: Ongoing expenses of owning a property (loan, taxes, insurance, utilities, maintenance)
- Why it matters: Every month you hold costs money; longer holds = higher total carrying costs
- Key detail: Same concept as holding costs; "carrying" is broader (rentals too)
- Related: Holding costs, flip timeline, interest rates
- Watch for: Vacant properties often have higher insurance and utility costs
How It Works
Loan payments. Principal and interest (or interest-only). The largest component for leveraged properties. Interest rates directly impact this—a 2% rate increase can add hundreds per month.
Property taxes. Prorated monthly. Vary by county and assessed value. Non-negotiable in most cases.
Insurance. Homeowner's for occupied; vacant or builder's risk for rehabs. Vacant policies cost more.
Utilities. Electric, gas, water, sewer. During rehab, contractors need power. For rentals, sometimes tenant-paid; for flips, owner-paid.
Maintenance. Repairs, lawn care, snow removal. Even vacant properties need basic upkeep.
HOA. If applicable. Fixed monthly.
Real-World Example
David Martinez holds a 1,400 sq ft flip in Phoenix for 8 months. His carrying costs (same as holding costs here):
- Loan: $195K at 9% interest-only = $1,463/month
- Property tax: $320/month
- Insurance (vacant): $185/month
- Utilities: $165/month
- HOA: $0
Total: $2,133/month × 8 months = $17,064.
His flip profit before carrying: $78,000. After: $60,936. Carrying costs consumed 22% of his gross profit.
If he had closed in 6 months: $2,133 × 6 = $12,798. He'd have kept $4,266 more. He now builds shorter flip timelines into his underwriting.
Pros & Cons
- Makes the cost of ownership explicit
- Encourages faster execution
- Helps compare financing options
- Applies to both flips and rentals
- Easy to underestimate
- Market shifts can extend hold periods
- Interest rate increases compound quickly
- Vacant insurance can surprise
Watch Out
- Interest rate risk: Rising interest rates increase loan payments; model at current rates
- Vacant premium: Insurance for vacant properties often costs 50–100% more
- Timeline risk: Extended flip timelines multiply carrying costs

The Takeaway
Carrying costs are the price of time. Every month you hold, you pay. For flips, minimize them by shortening the flip timeline and choosing efficient financing. For rentals, they're part of operating expenses—manage them to protect cash flow.
