Run the numbers before you call.

Free calculators we use every day — value, lease cost, buy vs. lease, financing, 1031 deadlines, space needs, NNN costs, rent rolls, property taxes, cap rate pricing, IRR and 1031 tax deferral. Nothing you type leaves your browser unless you send it to us.

Income approach

What's my property worth?

Value an income property the way buyers and lenders do: net operating income divided by a cap rate. The hard part in Montana is the cap rate — sale prices aren't public record, so national websites can't see them. We can.

A calculator gives you a number. A broker opinion of value gives you the comparable sales behind it — from the files only local brokers have.

Tenants

Compare two lease quotes

Gross vs. NNN, free rent, TI and escalations make quotes hard to compare. This puts both on the same footing: total cost over the term and an effective rate per square foot.

Owner-users

SBA 504 and 7(a) loans can get an owner-user in with 10% down. We'll show you what's for sale that fits, and what it would cost to own.

1031 exchange

Your 1031 deadlines

Enter the date your relinquished property closed. You have 45 days to identify replacement property and 180 days to close on it — no extensions.

Forty-five days goes fast in a thin market. We map your identification list against real inventory, including property that isn't advertised.

Planning

How much space do I need?

A starting range for office space from headcount and layout. We'll refine it on a tour — storage, conference rooms and parking change the answer.

Tell us the headcount and how you work, and we'll pull every space in town that fits — listed or not.

Landlords & tenants

What will NNN / CAM cost?

Add up the pass-through expenses on a building and see the cost per square foot and what one tenant's share comes to. Landlords use it to set the NNN estimate; tenants use it to check one.

We reconcile CAM for the buildings we manage and review it for tenants before they sign — most disputes start with a pass-through nobody checked.

Rent roll & lease expirations

Enter each suite's size, monthly rent and lease end date. You'll get occupancy, rent per square foot, the weighted average lease term left (WALT) and how much income rolls each year.

Leave rent blank for vacant suites.

Lenders and buyers price the rollover. We'll underwrite the rent roll against market rents and tell you what it means for value.

Uses today's date for remaining term. Month-to-month or expired leases count as zero term.

Montana property tax

Estimate a commercial property's taxes

Montana taxes commercial property at a percentage of its assessed market value, then applies your district's mill levy. For 2026, commercial and industrial property is taxed at 1.50% of value under $2,274,000 and 1.90% at or above it.

Values were reappraised for 2025–2026 and rates changed both years. If your assessment looks high, an opinion of value is the starting point for an appeal.

Which cap rate is right is the whole question. We know where Great Falls deals actually closed, because Montana doesn't publish sale prices.
