Partial Owner-Occupied Property: Loan Classification and the Investor Experience Carve-Out

If your business occupies part of a commercial building and arm's-length tenants occupy the rest, and your share falls below the owner-occupancy threshold, the property is classified as an Investor Property — not owner-occupied. That classification carries a benefit most borrowers in this position never hear about: our guidelines state that for these partial owner-occupied properties, the standard investor experience requirement does not apply.

That single sentence is the reason this page exists. A borrower who has never owned an investment property, and who would be measured against an experience bar they cannot clear on a straight investor deal, is not measured against that bar here. Below is how the classification works, what the carve-out does and does not reach, and what still has to be true for the file to close.

The classification is a two-part test, and you only need to fail one

There are two definitions in play, and they use different units of measurement. Getting them confused is the most common mistake we see on mixed-occupancy files.

A property is Owner Occupied when the borrower's business occupies and operates from it, or the borrower resides in a residential unit of it, or it is leased to a related entity majority owned or controlled by the borrower. But qualifying is not just about the relationship — to qualify as Owner Occupied, the borrower must utilize 50% or more of the property's net rentable area. That is a square-footage test.

A property is classified as an Investor Property if at least 50% of its effective gross income is generated by arm's-length, third-party tenants. That is an income test. Multifamily, manufactured housing parks, 1–4 unit residential and PUD properties are Investor Properties regardless of occupancy.

Our companion post on [owner-occupied versus investor commercial property classification](/blog/owner-occupied-vs-investor-commercial-property-classification) works through the arithmetic of the 50% net rentable area test and the appraiser's authority to reclassify. Read that one for the threshold mechanics. This page picks up where a property has already landed on the investor side of the line while the owner is still in the building.

The guideline is explicit about the mixed case. Properties that otherwise meet the definition of an Investor Property but include partial borrower occupancy continue to be classified as Investor Properties. There is no hybrid category, no blended file, no partial credit. The property is an Investor Property, and it is underwritten as one.

What "partial owner-occupied" looks like in practice

A dentist owns a 6,000 square foot single-story office building. Her practice occupies 2,200 square feet. The remaining 3,800 is leased to an accountant and an insurance agency, both unrelated to her, both on written leases at market rent. She uses roughly 37% of the net rentable area. Third-party tenants generate the majority of the building's effective gross income.

That building is an Investor Property. The dentist has owned no other real estate in her life except her house.

On a conventional investor file, that biography is a problem. The experience table would place her at the bottom of it. On this file, our guidelines remove that test.

The experience carve-out

Here is what a borrower on a standard investor property is measured against.

Ownership of a primary residence does not qualify toward experienced investor status. That note in the guideline is doing real work: a borrower who owns only the home they live in is Inexperienced, not Experienced, no matter how long they have owned it.

Read the top row carefully. "Ineligible" is a category. A borrower who has not owned any property for at least 12 months does not simply get a lower LTV on a standard investor deal — they do not meet the requirement at all.

The logic is not hard to reconstruct. The investor experience test exists because a pure investor is buying a business they may never have run: finding tenants, negotiating leases, managing turnover, holding a building through a rollover cycle. Track record is the proxy for whether they can do it.

An owner whose own business operates out of the building is not that borrower. They are already at the property. They already have an operating enterprise inside it, with its own history and its own cash flow, and the third-party space is secondary to why they own it. The guideline recognizes that the investor track-record test is measuring the wrong thing on this file, and switches it off.

What the carve-out does not do

This is the part that costs people money if they read too much into one sentence. The carve-out is narrow. It removes one named requirement. It does not make the file easier in general, and several other experience-flavored requirements sit elsewhere in the guidelines and are untouched by it.

Self-management still carries an experience requirement. We require that the subject property be managed by an experienced, reputable professional — either a third-party property manager or self-managed by the borrower or a borrower affiliate. If a commercial property is self-managed, the borrower or guarantor must live within 200 miles of the property and have a minimum investor experience as defined in that table. For a Tier I multifamily or Tier I mixed-use property that is self-managed, the distance shrinks to 50 miles, with the same minimum investor experience. Separately, we may allow self-management regardless of property type or distance where the borrower or guarantor can verify 5 plus years of investor or ownership experience with real estate of like kind, size and geographic area as the proposed collateral.

The guideline does not state how the partial owner-occupied carve-out interacts with the self-management experience language. Those are two different sections, and the carve-out speaks to "the standard investor experience requirement," while the property management section imposes its own condition on self-managers. We are not going to paper over that. If you intend to self-manage a partial owner-occupied investor property and you have no investment property history, raise it at application and get the answer in writing before you spend money on third-party reports.

Using a third-party property manager avoids the question entirely. Where the property is managed by a third party, there must be an executed property management agreement, and where the manager is an individual, a resume reflecting at least 2 years plus experience managing income producing properties, real estate, or relevant property management experience. That resume is not required if the individual is confirmed to be a licensed real estate agent or broker.

Restaurants, bars and daycares have their own history requirement. For restaurant, bar and daycare properties, the operating business — whether tenant-operated or owner-occupied — must demonstrate a minimum of three years of continuous operating history at the subject property or at another current or previous business location. We may request documentation necessary to verify that history. If your business is one of these three and it occupies part of a building you are financing as an Investor Property, that three-year test applies to it. The investor experience carve-out does not reach it.

Layered risk still applies. FICO, DSCR and LTV each set individual minimum and maximum limits, and where one parameter approaches its threshold, other parameters may be tightened. Removing one test does not remove the underwriter's ability to tighten another.

The 25% affiliate trigger

There is a second provision that speaks directly to the mixed case, and it runs the other direction — it adds documentation rather than removing a test.

If a borrower-affiliated business occupies 25% or more of the property's rentable square footage, or contributes 25% or more of the property's rental income, we may require additional documentation, including a Business Profit and Loss Statement and business bank statements, to evaluate the operating business.

Note the hedging: "may require." It is not automatic. But plan for it. The practical effect is that a borrower whose business occupies a meaningful slice of the building can find themselves producing operating-business financials on a loan they thought was a pure rental underwrite. That is not inconsistent — if a quarter or more of the building's income depends on a business you control, the health of that business is part of the collateral analysis.

The two 50s and the 25 are the three numbers that decide how a mixed-occupancy file is processed. They are measured in three different units — square footage, income, and either — so a property can sit on different sides of each.

What the investor classification changes downstream

Classification is not a label. It routes the file into a different underwriting method, a different coverage test and a different menu of documentation programs.

The underwriting method is the substantive change. On an owner-occupied file we determine Global Debt Service Coverage, which pulls in personal and business obligations. On an income-producing property we determine the property's own Debt Service Coverage Ratio — underwritten net operating income divided by annual debt service payments. A mixed-occupancy property classified as investor is coverage-tested on the property.

The Lite Doc program is applicable to investor properties only, relies on the subject property's cash flow for repayment, and requires no personal or business tax returns. That option is not on the table for an owner-occupied file. It is on the table here — subject to everything else in the file, and subject to the 25% affiliate trigger potentially calling for business financials anyway.

There is also a fallback path in both directions. If, under the complete or lite program, an investor loan does not meet the required 1.15x DSCR, it may be converted to the No Doc Streamline program, which requires a minimum FICO of 700, caps LTV at 75% on purchase and 70% on rate-term refinance and cash out, and requires 1.00 coverage based on the rents the appraiser used to derive property value. No Doc Streamline requirements must be met in full. Economic occupancy is not permitted for No Doc Streamline, or for transactions converted to it during underwriting.

Where this trips people up

Treating the two 50% tests as one test. A borrower can use 45% of the net rentable area and still generate a majority of the building's income from their own operation if the third-party space is cheap and vacant. Square footage and effective gross income are different measurements and they do not have to agree. Both provisions are in the guidelines and both matter.

Assuming the appraiser will follow the rent roll. Appraisers may classify a property as owner occupied based on use, control and economic benefit, particularly where ownership is shared among related parties, the property is operated by a family business, or no arm's-length lease exists. Underwriting may classify a property as an investment property where owner occupancy does not meet the 50% threshold. The percentage of owner occupancy must be documented in the Commercial Real Estate Summary. Classification is determined in underwriting on the documented facts, not by the label on your application.

Reading the carve-out as a general leniency. It is one sentence removing one named test. The property still has to be an eligible type. It still has to meet the 75% occupancy requirement and the stabilization requirement — 75% occupancy over a 90-day trailing underwriting period prior to application. The guarantors still have to meet the credit standards, including a minimum FICO of 650 for the primary guarantor and 640 for all others, with all other borrowers and guarantors at a minimum of 640 where there are multiple.

Forgetting that the operating business is still under a microscope. The building being classified as an investor property does not put your company out of view — the 25% trigger above still reaches it.

What this page does not do

This is a description of how our SBC guidelines classify mixed-occupancy commercial property and how the partial owner-occupied experience carve-out reads. It is not an approval, a pre-qualification, a rate quote or a commitment to lend.

It does not tell you the maximum LTV your file will support. The guideline states that the standard investor experience requirement does not apply to partial owner-occupied investor properties; it does not state what LTV grid governs in its place, and we have not filled that gap with a number here.

It does not resolve how the carve-out interacts with the self-management experience condition in our property management requirements. Those are separate sections and the guideline does not reconcile them.

It does not price the loan — pricing is determined by loan program, property type, credit score, LTV, amortization term, loan amount and occupancy, under the current pricing matrix. It does not address third-party report costs, timelines, closing costs or reserve requirements, and it does not cover the 1–4 unit residential programs, which are governed by separate guidelines.

Zoning, permitted use, lease enforceability and the tax treatment of renting space to your own entity are legal, municipal and accounting questions. Take them to your attorney, your accountant, or the municipality with jurisdiction over the property. We underwrite the loan; we do not advise on those.
