Cost classification

Break-even is only useful if land, construction, sales costs, and overhead sit in the right buckets. Here, the Month 27 break-even depends on allocating $11.8M of land and $42.0M of construction to project inventory, not burying them in overhead.

Expense	Cost	Break-Even Treatment	Common Mistake
Land acquisition	Semi-fixed	Allocate the $11.8M owned-site purchase total across project inventory before measuring unit margin.	Treating owned sites as monthly rent, even though rental cost is $0.
Construction budgets	Variable	Allocate the $42.0M construction budget to homes as sold, tied to each community’s build plan.	Hiding construction overruns in overhead instead of unit economics.
Sales & Brokerage Commissions	Variable	Apply commissions to closed-sale revenue at 3.5% in the first year, stepping down to 2.5% by the fourth year.	Modeling commissions as fixed payroll and missing margin drag on each sale.
Project-Specific Marketing	Variable	Apply marketing to revenue at 1.5% in the first year, stepping down to 0.8% by the fourth year.	Double counting marketing by also loading it into sales payroll.
Office Rent, Utilities & Internet, Insurance, Professional Fees, Software, Travel	Fixed	Carry the full $17,000 monthly overhead across the company from Month 1 through Month 60.	Assigning overhead only to active communities and understating early cash burn.
Salaried project team	Semi-fixed	Model payroll in staffing steps, rising from about $20,000 per month in the first year to $65,000 per month in the fifth year.	Missing FTE step-ups when construction, finance, sales, and admin roles come online.

How does break-even shift from a lean three-site plan to a full six-site build?

Scenario table

Break-even moves faster when more sites are selling and fixed overhead gets spread across more closings. The lean case carries the heaviest load per sale, while the full build-out can recover sooner if absorption stays ahead of Month 27.

Planning assumptions only; actual break-even will move with sales pace, pricing, and carry costs.

Scenario	Monthly Revenue	Variable Costs	Fixed Costs	CM Ratio	Operating Profit	Break-Even Signal
Lean case: First three owned sites	$55k-$74k	$18k-$37k	$37k	50%-67%	$0	Lower overhead helps, but the small pipeline leaves little cushion.
Base case: Six-site model	$87k-$116k	$29k-$58k	$58k	50%-67%	$0	Month 27 is the core break-even point, so cash stays tight until closings scale.
Full case: Six-site faster absorption	$123k-$164k	$41k-$82k	$82k	50%-67%	$0	Stronger absorption can turn break-even into a cushion after Month 27.

What breaks the break-even plan if closings slow or costs run hot?

Stress test

The plan is tight: minimum cash hits -$13.194M in Month 26, and breakeven only arrives in Month 27. If closings slip or overhead moves toward the top of the $37k-$82k/month range, cash needs rise before sales catch up.

Stress Case	Changed Assumption	Break-Even Revenue	Revenue Gap	Risk Signal
Current plan	No change.	$467,000	$0 cushion	Breakeven lands in Month 27, so cash is still thin.
Revenue shortfall	Average selling price or closings fall 15%.	$550,000	$83,000 gap	A small sales miss pushes breakeven out and widens the cash hole.
Fixed-cost increase	Monthly overhead rises to $82,000.	$1,036,000	$569,000 gap	Higher payroll or office spend lifts the revenue bar fast.
Margin pressure	Variable load rises from 5% to 10%.	$493,000	$26,000 gap	Heavier sales and marketing spend leaves less room for delay.
Combined pressure	Construction spend rises 10% and sales slip.	$1,093,000	$626,000 gap	Cash needs rise before closings arrive, so Month 27 slips.

What should you verify before buying land for the first townhome community?

Founder checklist

Don’t commit to land or construction until site control, permits, and the full land-plus-build budget are locked. This model runs to about negative $13.2M in Month 26 before breakeven in Month 27, so reserves and sales timing have to be real.

1Site control$1.2M-$2.8M

Verify you can secure each site before you wire for land, because owned purchases run from $1.2M to $2.8M each and that cash leaves early.

2Permit pathMonth 9

Check entitlement and permit timing before you start field work, because construction begins as early as Month 9 and slips push the whole schedule.

3Budget lock$53.8M

Confirm the full land-plus-construction budget is fixed, because the six communities total $53.8M and overruns hit cash fast.

4Fixed load$17K/mo

Keep office and software overhead lean, because the base nonpayroll fixed load is $17K a month before payroll and project costs scale up.

5Staffing ramp$20K-$65K/mo

Stage hiring by project phase, because payroll starts near $20K a month and rises to about $65K a month as more sites move into build and sales.

6Cash runwayMonth 26-27

Hold reserve cash through the trough, because minimum cash bottoms around Month 26 and the first sale starts in Month 27, so demand must be ready before launch.
