Units, Area & Rents

List each rentable unit, its square footage, and its rent. NNN costs are split across tenants by their pro-rata share of the total building area.

Enter each suite's rent as $/mo (total monthly rent) or flip the selector to $/SF (rate per square foot per month). Leave it blank to use the default rate below — the footer shows the blended $/SF/mo.

Default rent rate (for suites without their own)

Why we ask: rent is never part of the NNN rate — but the management fee (Section 03) is a % of gross rents, and the per-suite "All-in/mo" totals need it. Suites with a rent entered above ignore this. Don't know it yet? Leave blank — the management fee just falls back to the $350/mo minimum.

Management & Admin Fees

Will your lease include a property management fee?

Most NNN leases pass through a management fee. The Landmark standard is 5% of gross rents, with a minimum of $350/month. It flows into the expense list below automatically.

Enforce $350/month minimum

Does your lease allow an administrative fee on operating expenses?

Many NNN leases let the landlord add a 10–15% administrative fee on top of operating expenses (separate from the management fee). Check your lease language — if it's in there, don't leave it on the table.

Operating Expenses

Enter what the building actually spends. Toggle each line between /mo and /yr — whichever you know. Not sure what a line should cost? Tap the 💡 for a rule-of-thumb range sized to this building. Doesn't apply? Hit the × to remove the line — it tucks into a "Hidden" chip you can restore anytime. But scan the whole list first: the most-missed costs are the ones that blow a budget mid-year.

0 of 0 lines

Fills every empty line at the mid-to-upper end of its 💡 range, sized to this building. Rough draft — fine-tune the big lines.

Add as many asset-specific lines as you need — roof reserve, signage, a special assessment — and label each one. Every line has a 📝 for notes.
