What a T-12 is and why it matters
A T-12, or trailing 12-month operating statement, shows the building's income and expenses over the most recent 12 months. On a 5-10 unit building, it is one of the documents that determine the loan size, because many small-balance programs measure coverage as net operating income (NOI) divided by annual debt service.
The problem is that sellers' statements are often not built for underwriting. A self-managing owner may not charge a management fee, may pay some expenses personally, and may have deferred repairs for years. The seller's NOI can look much higher than what a new owner will actually earn. Underwriters correct for that, and you should too.
Adjustment 1: Vacancy and credit loss
Even if every unit is leased today, lenders apply a vacancy and credit loss allowance to gross rent. On a small building, one vacant unit is a large share of income, so the allowance is real. If the actual T-12 shows more vacancy than the allowance, the lender typically uses the higher of the two.
Adjustment 2: Management
If the seller self-manages, there is often no management expense on the statement. Lenders usually add one anyway, because a buyer may hire a manager, and because the owner's time has value. Even if you plan to self-manage, expect the lender to include a management fee.
Adjustment 3: Today's property taxes
Texas property taxes are often the largest expense on a small apartment building. The seller's tax bill reflects the seller's appraisal district value, which may be well below your purchase price. Lenders typically use the current bill, or a projected bill based on the price. Estimate the next bill yourself; see Texas property taxes on a 5-10 unit building.
Adjustment 4: Today's insurance
Insurance premiums on Texas small apartments have changed quickly in recent years, especially in hail-prone and coastal areas. The seller's policy may also have lower coverage or a higher deductible than a lender will accept. Use a real quote on the building with the coverage the lender will require, including windstorm or flood where applicable.
Adjustment 5: Replacement reserves
Roofs, HVAC units, water heaters, appliances and flooring wear out. Many programs add a per-unit annual allowance for replacements, whether or not the seller spent money on them last year. Older buildings may get a larger allowance or a required reserve account.
Adjustment 6: Repairs and turnover
If the seller deferred maintenance, the T-12 repair line may be unusually low. Lenders compare it with typical costs for buildings of similar age and size. If a big repair happened last year, they may remove it as a one-time item. Turnover costs, such as cleaning, painting and make-ready between tenants, are real recurring expenses and should show up.
Adjustment 7: Owner-paid utilities
In master-metered buildings, the owner pays water, and sometimes electricity or gas, for every unit. Those costs should be on the T-12 at actual levels. If the seller bills tenants back, lenders look at whether reimbursements are documented and consistent with Texas rules. See master-metered utilities and DSCR.
Adjustment 8: One-time items
Remove anything that will not repeat: a one-time insurance payout, a large legal fee, a special assessment or an unusual repair. The goal is a statement that reflects a typical year for a new owner.
A worked example
Illustration with user-style numbers for a 7-unit building:
| Line | Seller's T-12 | Normalized |
|---|---|---|
| Gross rent | $96,600 | $96,600 |
| Vacancy and credit loss | $0 | -$4,800 |
| Property taxes | -$12,500 | -$18,900 (on purchase price) |
| Insurance | -$4,100 | -$6,300 (current quote) |
| Water and trash (owner-paid) | -$5,200 | -$5,200 |
| Repairs and turnover | -$2,100 | -$5,600 |
| Management | $0 | -$7,700 |
| Replacement reserves | $0 | -$2,100 |
| Net operating income | $72,700 | $46,000 |
The same building, with the same rents, shows an NOI more than a third lower after normalization. If annual principal and interest on the loan you want is $52,000, the seller's numbers show comfortable coverage (about 1.40), while the normalized numbers show coverage under 1.00 (about 0.88). That gap is a price conversation, not a financing problem. Try your own numbers in the 5-10 unit DSCR calculator.
Put the normalized T-12 to work
Once you have a normalized statement, use it three ways: to check coverage in the calculator, to decide what you can pay, and to present the building to us. A file that arrives with a seller T-12 and your own normalized version side by side moves faster, because it shows you understand how the building will be underwritten.
Questions investors ask
Do lenders use the seller T-12 or their own numbers?
Both. They start with the seller's statement and then normalize it with their own vacancy, management, reserve, tax and insurance assumptions.
Will a lender add a management fee if I self-manage?
Usually, yes. Most small-balance programs include a management expense regardless of who manages the building.
What if the seller has no T-12?
Reconstruct it from bank statements, tax bills, insurance and utility bills. If there's no usable history, the building may need bridge financing first.
