70% rule check: 70% of $319,000 minus $52,000 of rehab gives a max offer of $171,300. You’re $10,700 over it. Not a deal-breaker on its own, but your margin for surprises is thinner.

What this means

Flips live and die on the sale price and the calendar. If the margin is thin, rerun it with a lower sale price and two extra months. If it still works, you have room for the surprises every rehab brings.

The basics

What a flip really nets

Profit is the sale price after commission and seller costs, less everything it took to get there: the purchase and its closing, the rehab, each month you carry the house, and the lender’s interest and points.

How it’s worked out

Profit = Sale − selling − buying − rehab − holding & loan

  • Return on cash: profit divided by the cash you put in (everything not covered by the loan).
  • Annualized return: the same return spread over a year, so a 6-month flip can be compared with a rental.
  • Break-even sale price: all costs before selling, divided by what’s left after selling costs. Below it, you lose money.
Worked example

A Garland fixer bought at $182,000, $52,000 of rehab, sold for $319,000 five months later. A hard-money lender funds 90% of the price and the full rehab at 11.5% plus 2 points.

Sale price
$319,000
Selling costs (7.5%)
-$23,925
Purchase, closing, rehab
-$237,900
Holding (5 mo)
-$5,250
Loan interest & points
-$14,656
Profit
$37,269

An 11.7% margin and about 89% return on the $42,006 of cash in. Any sale under roughly $278,700 is a loss, and each extra month of carry costs about $3,118.

The verdict

How Kwalifai grades a flip

We grade on margin: profit as a share of the sale price. It tells you how much can go wrong before the deal starts costing you money.

Pencils out

10%+ margin

Profit is at least 10% of the sale price. Enough cushion for a rehab overrun or a slower sale.

On the edge

5% to 10% margin

It makes money on paper, but one surprise could take most of it. Look for a lower price or a tighter rehab.

Doesn’t pencil

Under 5%, or a loss

Not enough room for the things that go wrong on every flip.

Avoid these

Blind spots that flatter a flip

01

List-price comps

Use recent sold comps of similar finish, size, and street. The sale price moves profit more than anything else.

02

Rehab overruns

Old houses hide things. Budget a 10% to 15% contingency and check how much overrun the deal can take.

03

Forgetting the exit

Commission, seller-paid closing, and buyer concessions often total 7% to 9% of the sale.

04

Points paid on day one

Hard-money points are paid up front and never come back. They count even if you sell fast.
