Can rental income be used to qualify for a commercial mortgage?

Yes — for commercial income-producing properties, the primary qualifying metric is typically the Debt Service Coverage Ratio (DSCR), which measures the property's net operating income against the proposed debt payment. The borrower's personal income is secondary in most commercial underwriting scenarios.

What credit score is needed for a commercial loan?

Most commercial lenders require a minimum score of 650–680 for the guarantor. SBA loans typically require 680+. DSCR loans for investment properties typically start at 680. Hard money and bridge lenders are more flexible on credit and focus primarily on the property and equity position.

How much down payment is required for an investment property?

Conventional investment property loans typically require 15–25% down depending on the number of units and the lender. DSCR loans typically require 20–25% down. FHA loans require only 3.5% down for 2–4 unit properties where the borrower occupies one unit. Hard money loans often allow 30–35% LTV.

Can I use a DSCR loan for a short-term rental (Airbnb) property?

Yes. Many DSCR lenders accept short-term rental income verified through Airbnb/VRBO income history or market STR rent estimates. Bakersfield has growing Airbnb demand from oil industry visitors, hospital proximity, and local events. Dan works with lenders who specifically accommodate STR income for Kern County properties.

Can I use future rental income to qualify for a mortgage?

For conventional and FHA loans on investment properties, lenders use the appraiser's market rent estimate (from a 1007 rent schedule), not actual signed leases, for properties not yet rented. DSCR loans use the same appraiser market rent to calculate the DSCR ratio. You do not need an existing tenant in place to qualify.

Residential vs. Commercial Financing: What Every Realtor Should Know

Most Realtors have residential transactions dialed in. But when a client wants a duplex, a small office building, or a mixed-use property, the financing conversation gets more complicated, and the gaps in knowledge can cost you a deal.

Understanding the fundamental differences between residential and commercial financing isn't just helpful, it's essential for any agent working with investors or business owners.

The Core Dividing Line: Units and Use

The most important rule: residential financing (Fannie/Freddie/FHA/VA) applies to 1–4 unit properties. The moment a property hits 5 units, it becomes commercial real estate, regardless of whether it looks like a big apartment building or a small five-plex. Commercial financing is required.

Owner-occupancy matters too. A business owner buying a warehouse to operate their business out of needs commercial financing even though it's a business real property purchase. A homebuyer buying a duplex to live in one unit and rent the other can use residential financing.

Timeline Differences

Residential purchase loans typically close in 21–45 days. Commercial loans commonly take 45–90 days. SBA loans can take 60–120 days. Failing to set correct timeline expectations at contract is one of the most common ways agents create problems in commercial transactions.

If your buyer needs a 30-day close on a 5-unit apartment complex, there's a problem. Brief them, and the listing agent, on realistic timelines before going into contract.

Underwriting Differences

Residential loans underwrite the borrower: income, credit, DTI, and assets. Commercial loans underwrite both the borrower and the property. The lender wants to see the property's income (rent rolls, operating statements), occupancy, condition, and how the debt service compares to net operating income (DSCR).

Commercial appraisals focus on the income approach, what the property is worth based on its cash flow, not primarily the sales comparison approach used in residential. A commercial appraisal also takes longer and costs more ($2,500–$5,000 vs. $500–$700 residential).

Down Payment Requirements

Residential investment properties typically require 15–25% down. Commercial properties generally require 25–35% down for conventional commercial loans. SBA 504 loans can go to 10% down for owner-occupied commercial real estate. Setting buyer expectations on equity requirements is critical, showing up with 10% down on a commercial deal will end in disappointment in most cases.

What About Mixed-Use?

Mixed-use properties (retail on the ground floor, residential above) can fall into either category depending on the lender and the specific property. Generally, if more than 25% of the property's income comes from commercial tenants, residential financing won't work. This is property-specific and worth a conversation with your lending partner before making an offer.

Common Mistake: Assuming Any Lender Can Do Any Deal

A residential lender, even a highly capable one, may not be set up to originate commercial loans. And a commercial lender may not touch 1–4 unit residential investment properties the same way. Matching the deal to the right lending channel early saves everyone time. A broker with access to both markets is often the most efficient path.

How to Protect Your Commission

The best protection is a pre-qualification from the right lender type before writing an offer. For any property 5 units or larger, mixed-use, or owner-occupied commercial, the buyer needs to speak with a commercial lending specialist before going into contract, not after.

Getting this wrong costs you the deal, costs your buyer earnest money, and costs months of your time. Getting it right from the start is a competitive advantage.

Bottom Line

The 1–4 unit / 5+ unit line, the borrower vs. property underwriting distinction, and the longer commercial timelines are the three things every Realtor should have memorized. When a deal crosses into commercial territory, bring in the right financing expert early and the rest of the transaction becomes significantly smoother.
