Holding Costs Checklist for House Flippers

What counts as a holding cost on a flip?

Holding costs are where flips quietly lose money. Not because any one bill is big, but because every month of delay adds another full set of them.

A holding cost is anything that recurs because you own the property, as opposed to one-time renovation or transaction costs. The live Axelrad guide on cash to close and rehab draws groups these as "during the hold" costs: financing payments, taxes, insurance, utilities, and other project expenses.

The holding costs checklist

Go line by line and put a monthly number next to each one, even if it's zero.

Financing

• Monthly loan interest (on the amount drawn, if your loan works that way)
• Any monthly servicing or extension cost listed in your term sheet
• Interest on any secondary or partner money

Property

• Property taxes (monthly share of the annual bill)
• Insurance: vacant or builder's risk policy as required
• HOA or condo dues, plus any special assessments
• Municipal fees such as vacant property registration, where they apply

Utilities

• Electric (contractors need power)
• Water and sewer
• Gas or heating fuel (and winter freeze protection)
• Trash, if not covered by a dumpster

Upkeep and security

• Lawn care and snow removal
• Pool service, if any
• Security system, cameras, or lock changes
• Pest control

Your own time and overhead (optional but honest)

• Mileage and site visits
• Project management cost if you hire it out

How do you calculate monthly holding costs?

Add every line into one monthly figure, then multiply by your expected months from closing to sale closing, not to listing.

Example (hypothetical numbers): $240,000 loan, fully drawn for simplicity.

The 11% rate is a hypothetical placeholder for the arithmetic only, not an Axelrad rate. Use the rate on your own term sheet.

Now run the hold length:

Four extra months cost more than $12,000 here. That's often the difference between a solid flip and a break-even one.

How does draw-based interest change the math?

Axelrad's fix-and-flip page says borrowers pay interest only on the funds drawn, not the total loan amount. On a loan where rehab money is held back and released over time, early-month interest is lower than on a fully funded loan, then rises as draws go out. To model it, calculate interest month by month on the balance outstanding that month instead of using one flat number.

Example (hypothetical numbers): $160,000 funded at closing, $80,000 rehab released as $30,000 in month 2, $30,000 in month 3, $20,000 in month 4. Outstanding balance: $160,000 in month 1, $190,000 in month 2, $220,000 in month 3, $240,000 from month 4 on. Interest follows that curve.

How long should you assume you'll hold?

Longer than you think. Count from closing day to the day the sale closes and pays off the loan. That includes:

1. Permit and contractor start lag
2. Renovation
3. Final inspections and punch list
4. Listing prep and photos
5. Days on market
6. The buyer's financing and closing period

A useful habit: build your analysis at your expected hold, then show it again at plus two and plus four months. If the deal can't survive plus four, it's too tight.

Monthly burn-rate worksheet (fill in)

Monthly burn rate = the sum of every monthly holding cost; total holding budget = burn rate x (expected months + buffer months). Leave a line blank if it doesn't apply.

Who pays holding costs, you or the loan?

Usually you, from cash. Some loans are set up with an interest reserve that pays interest out of loan proceeds, which raises the loan balance. Taxes, insurance, and utilities are normally your responsibility either way. Ask your lender how interest is paid and when the first payment is due.

How do you reduce holding costs?

• Have bids, permits, and materials lined up before closing so work starts in week one.
• Order long-lead items (windows, cabinets, appliances) early.
• Shop insurance before closing, not at it.
• Price to sell, not to test the market for a month.
• Choose a loan term that fits your plan with room to spare, so you're not paying extension costs.

Which holding costs surprise flippers most?

Insurance and taxes. A vacant or under-renovation property may need a different policy than a standard landlord policy, and the premium can be higher. Property taxes can also be reassessed after a sale, so the bill you inherit may not be the bill you'll pay. Ask your insurance agent and check the local assessor's records before you close.

Key takeaways

• Holding costs recur every month: interest, taxes, insurance, utilities, dues, upkeep.
• Build a monthly burn rate and multiply by a realistic hold plus a buffer.
• Draw-based interest means your interest cost climbs as rehab funds go out.
• Each month of delay costs a full burn rate, so speed in the first weeks matters most.

Plan the hold, then fund it

The calculator on the fix-and-flip loan page includes months held and monthly holding cost so you can test scenarios. When the numbers work at plus four months, submit your deal.
