Which expenses stay fixed and which move with sales in a property auction business?

Cost classification

Break-even gets reliable only when fixed overhead is separated from deal-linked spend. In this model, rent and core admin set the monthly floor, while transaction fees, commissions, marketing, and hiring scale with auction volume.

Expense	Cost	Break-Even Treatment	Common Mistake
Office Rent	Fixed	Use $5,000 per month in the fixed overhead base.	Tying rent to transaction volume and understating slow-month burn.
Utilities & Internet	Fixed	Use $800 per month unless the office footprint changes.	Letting small utility swings distract from the true overhead floor.
General Software Licenses	Fixed	Use $1,500 per month as recurring operating overhead.	Moving core licenses into variable spend without a usage trigger.
Professional Services	Fixed	Use $2,500 per month for recurring accounting and legal support.	Confusing recurring advisory retainers with per-transaction legal work.
Transaction Processing Fees	Variable	Apply 1.5% in the first year, falling to 1.1% by the mature year.	Modeling processing fees as flat even though they rise with transaction value.
Sales Team Commissions	Variable	Apply 8.0% in the first year, falling to 6.0% by the mature year.	Counting commissions as fixed payroll and overstating contribution margin.
Seller and Buyer Acquisition Marketing	Semi-variable	Plan monthly budgets, but link spend to seller CAC and buyer CAC targets.	Treating the full budget as fixed while acquisition targets drive spend.
Staffing Additions	Semi-fixed	Add roles in steps when capacity expands, such as support in Month 13 and admin in Month 25.	Smoothing headcount monthly instead of modeling real hiring jumps.

How does break-even shift from a lean launch to a full-scale real estate auction model?

Scenario table

Break-even moves with scale because fixed payroll and marketing rise fast, while margin improves as the seller and buyer mix shifts toward higher-value, more repeat business. The lean case is tightest; the full case carries the widest cushion.

Planning figures are model assumptions, not guarantees, so actual break-even will move with deal mix, marketing efficiency, and staffing pace.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean launch	$2.30M	$0.29M	$1.77M	87.5%	$0.24M	Just above break-even, with a thin cushion.
Base case	$14.58M	$1.56M	$4.69M	89.3%	$8.33M	Well above break-even, so the model has room to absorb misses.
Full-scale rollout	$54.26M	$4.83M	$9.29M	91.1%	$40.14M	Far above break-even, with a strong scale cushion.

What breaks first if listings slow down or marketing gets more expensive?

Stress test

First-year break-even is about $2.03M. The main risks are fewer closed sales, faster-rising customer acquisition cost (CAC), and overhead stepping up before listings turn into wins.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$2.03M	$0 cushion	At plan, there is no cushion.
Revenue shortfall	Closed sales slip from about 21 to 18 per month.	$2.03M	$190K gap	Fewer seller listings and qualified bidders hit close volume first.
Fixed-cost pressure	Customer support and compliance hires start in the first year.	$2.23M	$205K gap	Overhead lands before volume does.
Margin pressure	Seller and buyer CAC rise above the base threshold, cutting margin to 85.5%.	$2.07M	$48K gap	Pricier acquisition pushes the target up.
Combined pressure	Lower close volume, early hires, and weaker margin all hit at once.	$2.29M	$260K gap	Volume and cost pressure stack up fast.

What should you verify before the first big commitment for a real estate auction launch?

Founder checklist

Do not commit to lease, hiring, or launch spend until seller supply, bidder demand, and the $69.0K monthly fixed load all clear the bar. The model also needs $405K of startup capex and $1.052M minimum cash in Month 1, so this check is mostly about cash and pipeline, not hope.

1Seller pipeline200 sellers

Verify you can source about 200 sellers at or below the $2,500 CAC before you commit the $500K first-year seller marketing budget; otherwise supply will not support the auction calendar.

2Bidder demand1,600 buyers

Verify you can acquire about 1,600 buyers at or below the $500 CAC before the $800K buyer marketing budget; without enough bidders, auctions lose price pressure.

3Contribution margin87.5% CM

Check that the Year 1 variable load stays near 12.5% of revenue from transaction processing, hosting, sales commissions, and legal per transaction, so each sale still leaves room for fixed costs.

4Core overhead$69.0K/mo

Hold rent, software, insurance, professional services, and base payroll at or below this monthly load, because fixed costs move fast once the office and team are in place.

5Launch cash$1.457M

Keep enough cash for the $405K startup capex plus the $1.052M Month 1 minimum reserve, because the launch spends land before deal revenue does.

6Ops rampMonth 13

Confirm platform access, payment processing, insurance, compliance review, closing support, and staff coverage are ready by Month 13, or the auction calendar will outrun the team.
