How to Estimate Holding Costs on a House Flip (With Cuyahoga County Dates)
By the ACC Solutions team
Short answer: holding costs are what you pay every month you own the flip: loan interest, property taxes, insurance, utilities, upkeep and local registrations. Add them up as a monthly number, then multiply by the months from your purchase closing to your sale closing, including the time the house sits on the market and in escrow. In Cuyahoga County, also mark the two property tax due dates on your calendar, because a half-year bill can land in the middle of your rehab.
Written by the ACC Solutions team. County dates come from the Cuyahoga County Treasurer's 2026 tax collection calendar and Cleveland's rules from the city's vacant properties page, both read November 12, 2026. Every dollar figure in the worked example below is made up to show the math. ACC Software, part of ACC Solutions, makes the A.I. Deal Assistant mentioned at the end.
Step 1: List every monthly cost
- Financing: interest on your loan, or the return you give up on your own cash. Points and fees paid at closing are acquisition costs, not monthly costs, but an extension fee if the project runs long is a holding cost.
- Property taxes: the annual bill divided by 12, whoever ends up writing the check (see Step 3).
- Insurance: a vacant house under renovation often needs a different policy than an occupied one. Get the quote before you close.
- Utilities: electric, gas, water and sewer stay on for the crew, for inspections and for showings.
- Upkeep: lawn care, snow removal and securing the property.
- Local registrations: in Cleveland, a vacant house is registered with the city (Step 4).
Step 2: Count the months honestly
Holding time isn't just the rehab. It's:
- Rehab time, including permit and inspection waits,
- plus time on the market until you accept an offer,
- plus the buyer's closing period.
Use your own past projects and your agent's read on current days on market for that neighborhood. If you don't have either yet, run the deal at two lengths, one you expect and one two months longer, and see if the profit survives the longer one.
Step 3: Know when Cuyahoga County taxes are actually due
Ohio real estate taxes are paid a year behind. The Treasurer's calendar says charges payable in 2026 are for tax year 2025, and lists these 2026 dates:
| Date | What happens |
|---|---|
| February 19, 2026 | First half 2025 real estate taxes due |
| March 2, 2026 | 10% penalty on unpaid first half |
| August 13, 2026 | Second half 2025 real estate taxes due |
| August 23, 2026 | 10% penalty on unpaid second half |
| September 1, 2026 | 9% interest charged on prior years' delinquent real estate taxes |
| December 1, 2026 | 3% interest charged on delinquent real estate taxes |
Two practical points. First, if you own the house on a due date, the bill comes to you as a lump sum, even if the seller credited you for their share at closing. How taxes are prorated at your purchase and sale closings depends on your contract, so ask your title company to show the math. Second, many investor loans don't escrow taxes, so nobody pays the bill unless you do. A missed half costs a 10% penalty within days on the 2026 calendar. Look up the current bill on the Fiscal Officer's MyPlace property search before you offer.
If the county's value is well above what you paid in an arm's-length sale, that sale can be evidence in a valuation complaint. Our guide to appealing a property's tax value in Cuyahoga County covers the filing window and the one-complaint rule.
Step 4: Add Cleveland's vacant property registration
Cleveland's vacant properties page says that under Ordinance 3106 (February 2024), vacant properties must register and pay $70 per unit per year for one to three dwelling units. Commercial and industrial structures, including residential buildings with four or more units, pay $1,000 and may need a cash bond. Registration asks for ownership and lienholder information, a local agent in charge if the owner doesn't live in Cuyahoga County or the surrounding area, a Certificate of Good Standing for an LLC, and a property tax statement or payment plan. The page also says that from February 6, 2026, the city no longer requires a mandatory exterior inspection before the sale of a vacant one- to three-unit home, but vacant registration and enforcement continue.
The fee is small. Missing the registration and the local agent step is the bigger risk on an out-of-town flip, so put it on the closing checklist, not the rehab one.
A worked example (all numbers made up)
The figures below are invented to show the arithmetic. Only the Cleveland registration fee is real.
| Monthly cost | Made-up amount |
|---|---|
| Interest-only loan, $100,000 at 12% a year | $1,000 |
| Property taxes, $3,000 a year / 12 | $250 |
| Vacant or renovation insurance, $1,800 a year / 12 | $150 |
| Utilities | $250 |
| Lawn, snow and securing | $100 |
| Cleveland vacant registration, $70 a year / 12 (real fee) | about $6 |
| Monthly holding cost | about $1,756 |
At six months (three of rehab, two on the market, one to close), that's about $10,536. At eight months it's about $14,048. In this example each extra month costs about $1,756, which is the number to remember when a contractor slips or you're deciding whether to drop the list price now or wait.
Notice what drives it: the interest line is more than half the total. On a financed flip, cutting a month off the timeline usually saves more than shaving any other monthly bill.
Common holding cost mistakes
- Counting rehab months only. The house still costs money while it's listed and in escrow.
- Using last year's tax bill without checking for a new value. Look at the current bill and value on MyPlace.
- Forgetting a due date falls inside the project. Budget the cash for a half-year bill, even if it's partly reimbursed at closing.
- Treating occupied-home insurance as enough. Ask your agent about vacancy and renovation coverage before closing.
- No cushion. Run the longer timeline too, and keep the profit positive at that length.
Put holding costs next to the first read
The A.I. Deal Assistant gives you ARV from recent comps, a rehab estimate and projected flip profit from a property address or a Zillow or listing link. Our sales page doesn't itemize holding costs, so subtract your own monthly number times your months from the projected profit before you decide. If what's left still works at the longer timeline, the house is worth a walkthrough.
