How Much Does It Cost to Flip a House? The Full Cost Breakdown

Most people budget a flip as two numbers: what they pay for the house and what the rehab costs. On the deal below those two numbers are 79% of the spend — and the missing 21% comes to $46,250, which is more than the entire profit.

Here’s the full picture, itemized, on one deal. Every figure is a stated assumption for a mid-market Midwest-shaped project — your commission structure, transfer taxes and contractor pricing will differ. What holds is the shape: how much of a flip’s cost sits outside the two buckets everyone remembers.

The Deal

A 1,540 sq ft 3/2, bought at $138,000, renovated for resale at an after repair value of $265,000, held six months.

Non-purchase costs: $87,720, or 38.9% of the project. If you’d budgeted purchase plus rehab and called it done, you’d have been short by $46,250.

Bucket 1: Buy-Side Closing Costs — $12,050

What it takes to get the keys, on top of the price:

Two notes. First, financing drives this bucket — the $4,500 in origination and points is a hard-money cost that a cash buyer doesn’t have, and a conventional loan sits somewhere between. Second, the earnest money deposit doesn’t belong here. You write the check up front, but it’s credited against the purchase at closing. Counting it as a separate cost is the most common double-count in flip spreadsheets.

Bucket 2: Rehab — $41,470

Built room by room rather than guessed:

The two categories at the bottom are near zero here because this house’s systems were sound. On a house where they aren’t, those lines alone can add $25,000–$40,000 and push a six-month project to nine. That’s why the rehab number and the hold time have to move together. How to build the line-item estimate is here.

Bucket 3: Holding Costs — $12,000

The bucket that punishes optimism. $2,000 a month, every month you own it:

Vacant-property insurance is typically pricier than a standard homeowner’s policy, and standard policies often won’t cover an unoccupied house under renovation — worth confirming before you assume your quote is right.

Run the sensitivity, because this is where projects quietly bleed:

Six months of delay costs $12,000 and cuts the return by a third. Nothing about the house changed.

Bucket 4: Selling Costs — $22,200

8.4% of the $265,000 sale price:

Commission structures are negotiable and vary by market, so treat the 6% as a placeholder you replace with your own. What doesn’t vary much is the $6,300 of non-commission selling costs. Budget selling at 8–9% of ARV and you’ll rarely be surprised; budget it at 6% and you’re $6,300 short before you start.

Also missing from most spreadsheets: buyer concessions. It’s $0 in this budget, which assumes a clean sale. One inspection-driven credit request turns that into $3,000–$7,000 and it comes entirely out of your profit.

The Costs Nobody Lists

Four more that don’t fit a bucket but do hit the bank account:

Taxes on the profit. A flip held under a year is short-term — profit is ordinary income, not long-term capital gains, and if you’re operating as a business it’s subject to self-employment tax too. The $39,280 in the table above is pre-tax. Worth a conversation with a CPA before your first deal, not after.

Your own labor. If you’re swinging the hammer, either price it in at market rate or be honest that the return includes your wages.

Utility reconnection and deposits. Small, real, and always a surprise.

The deals you don’t buy. Inspections and appraisals on offers that fall through are a genuine cost of doing business. If you inspect four houses to buy one, the three that fell through are $1,500 of dead cost attached to the deal that closed — more if you paid for appraisals too. The fourth inspection is already in the closing-cost bucket above.

What This Means for Your Offer

Once you know the non-purchase costs are ~39% of the project, the offer price stops being a negotiation instinct and becomes an output. Every dollar you overpay comes out of the profit dollar for dollar — there’s no other line in the budget that behaves that way.

The practical version: build the four buckets once in a spreadsheet with the hold time and commission rate as live inputs, then solve backwards from the profit you require.
