An empty commercial space costs an owner money every single month it sits vacant — not just in lost rent, but in taxes, insurance, and often a personal guarantee on the mortgage that doesn't pause just because there's no tenant. Filling it well, with the right tenant on the right lease structure, is a different skill set than residential leasing. Here's how commercial tenant placement actually works in Louisville.

Start with the lease structure, not the tenant

Before you market a vacant office, retail, or industrial space, decide what kind of lease you're actually offering — it changes who applies and what rent you can realistically ask:

• Triple net (NNN): the tenant pays base rent plus their share of property taxes, insurance, and maintenance. Common for freestanding retail and single-tenant buildings, and generally the most landlord-friendly structure for predictable net income.
• Modified gross: the landlord and tenant split operating expenses by negotiated categories — common in multi-tenant office buildings where a clean triple-net split isn't practical.
• Full-service gross: the tenant pays one flat rent and the landlord covers taxes, insurance, and most operating costs — simplest for the tenant, but it puts more expense risk on you as the owner, so it needs to be priced accordingly.

Picking the wrong structure for your property type is one of the most common reasons a commercial space sits vacant longer than it should — asking a small retail tenant to underwrite a full triple-net structure when comparable space nearby is offered gross, for example, will quietly filter out applicants before they ever call.

Marketing the space

Commercial tenants — and the brokers representing them — search differently than residential renters. A listing needs real numbers up front: rentable square footage, the lease structure and asking rate per square foot per year, available date, parking ratio, zoning and permitted uses, and any build-out already in place. Vague listings ("great space, call for details") get skipped by serious commercial brokers who are filtering dozens of options for a client on a deadline. Louisville's current numbers are worth knowing going in: office space is repricing around a flight to quality with vacancy running about 22.8%, while retail is a much tighter market at roughly 3.1% vacancy with rents up nearly 6% year over year — which tells you a lot about how aggressively (or not) you can price and negotiate depending on which asset type you're leasing.

Vetting a commercial tenant

A commercial tenant's ability to pay rent depends on their business, not just their personal credit — which means the underwriting looks different than a residential application:

• Financial statements and tax returns for the business, not just a pay stub — usually 2-3 years if the tenant will provide them.
• A personal guarantee from the business owner, especially for a newer or smaller business without an established balance sheet, since the LLC itself often has minimal assets to stand behind the lease.
• References from a current or prior landlord and, where relevant, trade or supplier references.
• A realistic read on the business itself — is this a concept that fits the location and the surrounding tenant mix, or a good story with no track record in a space this expensive to re-lease if it fails.

Tenant improvement allowances and the letter of intent

Most commercial deals start with a letter of intent (LOI) before anyone drafts a full lease — a short document laying out the proposed rent, term, tenant improvement (TI) allowance, and key business terms, so both sides can agree on the shape of the deal before spending real money on lease drafting. A TI allowance is money the landlord contributes toward build-out (flooring, walls, fixtures) to get the space ready for that specific tenant's use — it's a real, often negotiable cost of leasing, and building a reasonable TI allowance into your pricing from the start usually leases space faster than holding firm on zero allowance and letting the space sit vacant while you wait for a tenant willing to build it out themselves.

What Winner Realty does

Winner Realty places both residential and commercial tenants across Louisville, Lexington, and Southern Indiana — pricing the space correctly for its asset type and current market conditions, building out a listing with the real numbers a commercial tenant or their broker needs to act quickly, and vetting applicants on the financial fundamentals that actually predict whether a commercial tenant pays rent for the life of the lease.

Frequently asked questions

How long does it typically take to fill a vacant commercial space in Louisville?

It depends heavily on asset type and how the space is priced and structured. Retail is a tight market right now, with vacancy around 3.1%, while office space is repricing with vacancy near 22.8% — meaning a well-positioned retail space can lease relatively quickly, while office space, especially older or lower-quality buildings, generally needs a more competitive rate or a real TI allowance to move.

What's a tenant improvement allowance, and do I have to offer one?

It's money a landlord puts toward build-out costs for a specific tenant's use. You don't have to offer one, but a reasonable allowance is often what makes your space competitive against others tenants are considering — factor it into your effective asking rent rather than treating it as pure loss.

Should I require a personal guarantee from every commercial tenant?

For any business without a long, verifiable financial track record, yes — the LLC signing the lease often has minimal assets of its own, and a personal guarantee is standard practice to give the lease real teeth.

What's the difference between triple net and gross leases for tenant placement?

Triple net shifts taxes, insurance, and maintenance costs to the tenant on top of base rent; gross leases roll those costs into one flat rent the landlord manages. The right structure depends on your property type and what's standard for comparable space nearby — mismatching it against market expectations is a common reason space sits vacant.

Does Winner Realty handle both residential and commercial tenant placement?

Yes. Winner Realty places tenants in both residential rentals and commercial spaces across the Louisville area.
