We found no federal rule that sets a minimum credit score or years in business for an owner-occupied commercial real estate loan. Each lender writes its own credit policy, and SBA's rulebook for the 504 and 7(a) programs, which finance many owner-occupied buildings, sets no score floor that we found either. What decides the file is the owners' credit, how long the business has run, its debt service coverage, the down payment and the building, and a 640 score or a company under two years old mostly changes how much cash and support the deal needs.
What lenders check before financing an owner-occupied building
The Interagency Guidelines for Real Estate Lending Policies (the FDIC's version in 12 CFR Part 365, current on eCFR as of October 30, 2026) list the credit factors a prudently underwritten real estate loan should reflect: the borrower's capacity to service the debt, the property's value, overall creditworthiness, the equity invested, secondary sources of repayment, and added support such as guarantees. On an Owner-Occupied building, capacity comes from your operating company's cash flow, so your financials come first.
The same guidelines set supervisory loan-to-value limits that a bank's internal limits shouldn't exceed: 85% for improved property, 80% for commercial construction, 75% for land development and 65% for raw land. Banks can make documented exceptions within aggregate caps, so treat these as supervisory guidelines, not loan terms.
Bank standards tightened recently. In the Federal Reserve's October 2026 Senior Loan Officer Opinion Survey, last updated November 2, 2026, the 61 domestic banks that responded reported tightening standards, on net, for every commercial real estate category in the third quarter of 2026, including loans secured by nonfarm nonresidential properties.
Is there a minimum credit score or years in business for an owner-occupied commercial real estate loan?
Not in any federal rule we found. SBA's SOP 50 10 8.1, effective October 1, 2026, tells 7(a) lenders to review the personal credit reports of owners and guarantors and discuss any credit issues, and it requires CDCs on 504 loans to pull personal credit reports for all guarantors. The score cutoff is the lender's own, so two lenders can read the same report and reach different answers.
SBA's credit elsewhere test adds a twist: a lender can't cite your failure to meet its conventional credit score policy as the sole reason you need an SBA loan. The file has to show another weakness, such as a need for a longer term than the lender's policy allows.
Time in business works the same way. SBA defines a New Business as one in operation for 2 years or less at the time the loan is approved. That status changes the down payment and how repayment is measured, and the SOP lists a lender policy that "normally does not allow loans to new businesses" as an acceptable reason a project needs SBA help.
Getting a commercial real estate loan with a 640 credit score
A 640 moves the weight onto the rest of the file. Lenders that consider it commonly want cash flow, equity and collateral to carry more of the case, and they'll look for why the score sits there. High card balances you can pay down read very differently from a collection last spring.
- Find the cause. Write a short, dated explanation for anything a lender will ask about, such as a paid tax lien.
- Show coverage room. Debt service coverage well above the program minimum makes a middling score easier to approve.
- Add equity or a guarantor. In a 504 deal, extra borrower contribution reduces SBA's share, and a creditworthy co-owner adds a second source of repayment.
If a lender turns you down, ask why. Under Regulation B, 12 CFR 1002.9, when your business had gross revenues of $1 million or less in its preceding fiscal year, the lender must notify you of its decision within 30 days after receiving a completed application and, on a decline, give the specific reasons or tell you how to request them. Saying you missed a qualifying score on its scoring system isn't a sufficient reason. Larger businesses get written reasons if they ask in writing within 60 days.
Buying a building when your company is under two years old
SOP 50 10 8.1 sets different math for a new business.
| Rule | Established business | New business (2 years or less) |
|---|---|---|
| 504 contribution, general-purpose building | At least 10% | At least 15%; debenture no more than 35% |
| 504 contribution, special purpose property | At least 15% | At least 20%; debenture no more than 30% |
| 504 bank (third party) loan | At least the net debenture (50% of costs if special purpose) | At least 50% of project costs |
| 7(a) equity injection | Lender's or SBA's equity analysis | Start-ups (1 year or less): at least 10% of total project costs |
For a standard 7(a) loan (over $350,000), a new business needs detailed projections showing debt service coverage of at least 1.15 within 2 years from funding. A projection-based 504 deal needs at least 2 years of projections, and if they show repayment in year 2 but not year 1, you must show enough liquidity to cover the year-one shortfall. On the 504 application, a new business also supplies a pro forma balance sheet and a monthly cash flow analysis for the first 12 months or 3 months past breakeven, whichever is longer.
Every individual owner of 20% or more signs an unlimited full guaranty on SBA loans, so a personal guarantee comes with the deal. One option waits: a 504 refinance without expansion requires the business to have operated for the full 2 years before applying. Outside SBA, a young company often needs stronger guarantors, such as owners with outside income or liquid assets.
Which path fits your profile
These profiles are assumptions for illustration. The credit descriptions aren't anyone's published cutoff; the SBA figures are program minimums.
| Assumed profile | Paths to test first | Cash in | What strengthens the file |
|---|---|---|---|
| 5+ years, strong credit, coverage well above 1.25 | Conventional bank loan, or 504 to keep cash | 504: at least 10%; conventional: lender policy | Three years of returns, clean interim statements |
| 3 years, 640 score, steady cash flow | SBA 504 or 7(a) with lenders that weigh the whole file | 504: at least 10%; a lender may ask more | Explanation letter, coverage cushion, added guarantor |
| 18 months, good credit, rising sales | SBA 504 as a new business | At least 15% | Two years of projections, year-one liquidity |
| Under 12 months | SBA 7(a) or 504 | 7(a): at least 10% of project costs; 504: at least 15% | Industry experience, monthly cash flow plan |
| Under 2 years, special purpose building | SBA 504 | At least 20% | Early appraisal and environmental work |
| Recent collections or late payments | Clean up first, then apply | Lender policy | Paid accounts, written reasons from any decline |
Worked example: a $1,200,000 warehouse for an 18-month-old company
Assumptions, all illustrative: a dry (general-purpose) warehouse priced and appraised at $1,200,000; closing costs and the fees financed into the debenture left out; last fiscal year's operating cash flow (EBITDA) of $98,000 after paying $66,000 in rent; new owner costs such as property taxes and insurance of $14,000 a year; an existing equipment loan of $1,500 a month ($18,000 a year); 7.00% with 25-year amortization on every loan; and a conventional policy of 75% loan-to-value. None of these are quotes.
| SBA 504, new business | Conventional, assumed 75% LTV | |
|---|---|---|
| Your cash in | $180,000 (15%) | $300,000 (25%) |
| Bank loan | $600,000 (50%) | $900,000 (75%) |
| CDC debenture | $420,000 (35%) | None |
| Monthly payment, new debt | $7,209 | $6,361 |
| Total annual debt service | $104,508 | $94,332 |
Total debt service is twelve payments plus the $18,000 equipment loan. The SOP lists rent payments among the cash flow adjustments a CDC must justify, so the rent that goes away can be added back: $98,000 + $66,000 - $14,000 = $150,000. Coverage is $150,000 ÷ $104,508 = 1.44 on the 504 path and $150,000 ÷ $94,332 = 1.59 on the conventional path. SBA's 1.15 minimum on $104,508 means $120,184 of cash flow, so this file clears it by $29,816. Count only the $98,000 and coverage drops to 0.94, so include your current lease.
If the building were cold storage with more than 50% of its square footage equipped for refrigeration, SBA would treat it as special purpose, and this new business would need at least 20% ($240,000), with the debenture at no more than 30% ($360,000). More on structure: SBA 504 vs. a conventional commercial mortgage.
The building gets underwritten too
Appraisal or evaluation. The bank appraisal rules, 12 CFR 323.3 for FDIC-supervised banks and 12 CFR 34.43 for national banks (current on eCFR as of October 30, 2026), exempt commercial real estate transactions of $500,000 or less, and business loans of $1 million or less that don't rely on selling or renting the real estate as the primary repayment source. The bank still needs an evaluation. A 504 project needs an appraisal when the property's estimated value is over $500,000.
Environmental review. SBA requires an environmental investigation of all commercial property taken as security, starting with a Phase I environmental site assessment when the property's current or past uses match SBA's environmentally sensitive industries. Under EPA's All Appropriate Inquiries rule (40 CFR Part 312), which supports a buyer's federal Superfund liability protections, the inquiry must be done or updated within one year before you acquire the property, and a Phase I under ASTM E1527-21 can satisfy it.
Occupancy. SBA financing requires your business to occupy at least 51% of an existing building, or 60% of new construction.
When the numbers are ready, one application through EQ Funding reaches lenders who compete to provide commercial real estate financing, including SBA loans. Lenders review the file and set the terms. The full checklist is in SBA 504 loan requirements.
