Chapter 10 · Money Management
Revenue isn't income.
Every dollar has a job.
Most money trouble in house flipping isn't a lack of work. It's money that lands in one account and gets spent as if all of it were yours. This chapter sorts every payment into its buckets, gets you paid faster, and gets you through the slow months.

The business keeps
Example numbers for full cosmetic flip. Set your own in Pricing and every tool here uses them.
Revenue is not income
Name every bucket before the money arrives, and you'll never spend the tax money on a new tool by accident.
Return
The Sale Proceeds
The final sale price minus the cost of the property, repairs, and closing fees is your gross profit.
Capital
Direct Costs
The money you paid to purchase the property and pay your contractors.
Holding
Holding Costs
Property taxes, insurance, utilities, and loan interest paid while the house is under construction.
Compliance
Tax Reserves
Funds specifically set aside for municipal taxes on your capital gains.
Profit
What You Keep
The net amount left over for your reinvestment and personal compensation.
The one habit that prevents the April panic
Every time a payment lands, move the tax part out the same day, into an account you don't spend from. When the quarterly payment is due, the money is already sitting there.
Move this much of every payment
1%
That's $46 of a $4,680 job: self-employment tax (14.1% of your pay) plus your income tax estimate.
To the tax account
$46
Stays in the business account
$4,634
An estimate from your pay and income tax guess, not tax advice. Your accountant or last year's return gives the real rate.
Profitable jobs can still empty the account
The work is done when the money is in the account. Collect at the job, take a deposit before you buy materials on big jobs, and never fund a customer's job with your own savings.
- 1
Milestone payments
On smaller projects, contractors may ask for a partial payment; always verify they have finished the specific milestone before paying.
- 2
Require completion
Never pay for a full renovation upfront. Always hold back a percentage (retainage) until the final punch-list items are complete.
- 3
Invoice procedure
Maintain a strict 'no pay without invoice' policy for all contractors.
- 4
Manage project cash flow
Keep a detailed spreadsheet of all incoming/outgoing funds. If a contractor or service provider is delayed, stop payment immediately until the dispute is resolved.

Jobs like this you can carry at once
Every job like this you book ties up $135 for 150 days. A busy month can empty the account even when every job is profitable.
If your sale is delayed, you must have enough cash to cover interest payments for months.
Estimate vs actual
A job that runs over on hours or materials can quietly pay you less than minimum wage. Track estimate against actual on every job for a month; the ones that run over are the ones to reprice.
Job Costing
Are your flips actually profitable?
Started from your Pricing numbers. The "really took" numbers are an example overrun: put in a real job.

Gross margin (after materials and labor)
We don't have a published margin range for this trade yet. Compare this job with your own last ten: the ones well below your average are the ones to reprice.
If your 'actual materials' are consistently higher, you are failing to account for waste or scope creep.
Taxes and paying yourself
Nobody takes taxes out of your pay any more. That's your job now, every month, not once in April.
Monthly Profit
Your month, after taxes
Started from your Pricing numbers: jobs a week, price, materials and monthly bills.
$5,950
Revenue / month
$4,446
Profit before tax
$1,124
Set aside for taxes
$3,322
Yours to keep
Set aside 25% of profit: $628 self-employment tax (2026 federal rate) plus $496 income tax at your rate. Your real rate depends on household income and state; last year's return or a tax pro tells you.
Taxes come out of profit, not revenue. Put in your own income tax rate if you know it; last year’s return shows it.
Tax Basics
Taxes and paying yourself
House flipping is typically considered business income rather than long-term investment, meaning it is subject to self-employment tax.
- •Keep tax funds in a separate high-yield savings account
- •Never touch these funds for renovation materials
- •This is a liability, not an asset
Not tax advice
I am an educator, not a CPA. Real estate tax laws are highly complex and vary by state. Because you are dealing with large sums of money, hire a qualified tax professional—it is an essential business cost.
How many slow months does your year have?
This trade's usual pattern. Change it to yours. Then scroll through the year.
Busy months bring in more than the bills.
Reserve
Save before, not during
In most trades the money comes in waves. The busy season has to pay for the quiet one, and the time to save is while the work is coming in.
The Reserve
Surviving the slow season
Bills and pay started from your Pricing numbers. Slow-season numbers are this trade's typical pattern; change them to yours.

Common Mistakes
What people get wrong
Avoid these traps to stay profitable.
1Combining personal and business funds.
It makes tax preparation impossible and risks your legal protections.
Instead: Use a dedicated business account for every expense related to the flip.
2Underestimating the 'holding costs'.
These costs accumulate daily, slowly eating your profit while you wait for a buyer.
Instead: Calculate holding costs for 3 months longer than you think you need.
3Spending the entire profit from the first flip immediately.
You need to build a larger cash reserve to handle the next, potentially bigger deal.
Instead: Reinvest a portion of every profit back into your reserve fund.
