Free tools for South Florida commercial real estate

Run the numbers yourself.

Frequently asked

Are these commercial real estate tools really free?

Yes — every calculator on this page is completely free and runs instantly in your browser with no signup. They were built by a working South Florida commercial tenant representative to help businesses, buyers, and owners make better real estate decisions.

Who are these calculators for?

Business owners and tenants sizing up or comparing lease space, buyers and investors underwriting a purchase, and owners deciding whether to sell or refinance — anywhere in Broward, Miami-Dade, or Palm Beach County.

How accurate are the results?

They use standard commercial real estate formulas and the assumptions you enter, so they're solid planning estimates — but not a substitute for a lender's quote, a CPA's tax analysis, an appraisal, or a full broker valuation. Treat the output as a starting point for a real conversation.

Do I have to give my information to use the tools?

No. Every tool gives you the full result instantly and free. You only share your contact details if you want Justin to review your numbers or send matching space — never to see the answer.

What happens after I run a tool?

If you choose, you can send your result to Justin and he'll pressure-test it against real comparable sales and lease terms. Representation is free to tenants and buyers because the landlord or seller pays the commission.
