Commercial real estate investing covers office, retail, industrial, and multifamily buildings with five or more units, and it plays by a different rulebook than a residential rental. Financing, leasing, and valuation all work differently, and an investor who assumes commercial is just a bigger version of a residential deal usually finds out otherwise partway through the first purchase.
How Commercial Leases and Valuation Actually Differ
Commercial leases are frequently triple net, meaning the tenant pays taxes, insurance, and maintenance on top of base rent, which shifts operating risk away from the owner in a way residential leases rarely do. Valuation also runs on net operating income and a market capitalization rate rather than comparable home sales, which means a commercial property's value moves with its lease terms and tenant credit quality as much as with the physical building itself.
Financing Looks Different Too
Commercial loans are usually underwritten to the property's income and the borrower's experience, not primarily to personal income the way a residential mortgage is, and they often come with shorter terms, five to ten years, followed by a balloon payment or refinance rather than a thirty-year amortization. Lenders also weigh tenant quality and lease length heavily, so a single-tenant building with a weak lease can be harder to finance than a multi-tenant property with a diversified rent roll.
Where Louisville's Commercial Sectors Stand
Industrial and logistics space near the UPS Worldport hub and along the Gene Snyder corridor has drawn sustained investor interest tied to e-commerce distribution. Medical office near the Norton and Baptist Health campuses has held steadier occupancy than general office downtown, which has faced the same post-pandemic vacancy pressure seen in many metros. Retail along Bardstown Road and in the Highlands has proven resilient where walkable, mixed-use corridors keep foot traffic strong, in contrast to some suburban strip centers competing directly with online retail.
Reading a Deal Beyond the Asking Cap Rate
An advertised cap rate is only as good as the trailing income used to calculate it, and a broker's pro forma projection can understate near-term vacancy risk or overstate achievable market rent on renewal. Pulling the actual trailing twelve months of income and expenses, not the projected version, is the difference between underwriting a deal and repeating the seller's marketing numbers back as if they were fact.
Paths In, From Direct Purchase to Passive Ownership
A first commercial purchase, small office condo or a single-tenant retail building, is the most hands-on entry point and the one that teaches the most about underwriting. Syndications and DSTs offer exposure to larger institutional-grade commercial assets, like a Class A industrial building or a grocery-anchored center, without the direct financing and leasing burden. An investor who already owns appreciated commercial property in the Louisville area and wants to move into a larger or more passive asset can often do so through a 1031 exchange, deferring the gain on the sale while repositioning into a different property type entirely.
Common 1031 Exchange Questions
What's the minimum size to be considered commercial real estate?
Multifamily is generally classified as commercial once it reaches five or more units; office, retail, and industrial properties are commercial regardless of size, which is what separates the financing and leasing rules from residential from the start.
Is commercial real estate riskier than residential rentals?
It carries different risks rather than uniformly higher ones. Commercial income can be more exposed to a single tenant's business health, but triple net lease structures often shift operating costs to the tenant in ways residential leases don't.
How much cash do I need to buy my first commercial property?
Commercial lenders commonly require 25% to 35% down, higher than typical residential financing, along with reserves and, often, prior ownership or management experience in the property type being financed.
Which Louisville commercial sectors have performed best recently?
Industrial and logistics space tied to the airport and distribution corridors, along with medical office near the major hospital campuses, have generally held occupancy better than downtown general office, though performance varies significantly by specific property and tenant.
Can I exchange a residential rental into a commercial property?
Yes. A 1031 exchange only requires that both the relinquished and replacement property be held for investment or business use; a residential rental can be exchanged into a commercial property of any type, and vice versa, as long as that use test is met.
What's T12 income and why does it matter more than a pro forma?
Trailing twelve month, or T12, income reflects what the property actually collected over the past year, while a pro forma is the seller's projection of future performance. Underwriting off the T12 figure is a more conservative and generally more reliable starting point than trusting the projection.
