Final terms depend on the lender’s guidelines, the property type, and the borrower’s complete credit picture.
The Quick Read: At five units, the building’s own paperwork decides the file. The lender wants a unit-by-unit rent roll, backed by leases and operating history, and then checks reserves: cash you hold after closing. Select lenders in the network often measure income differently at five units than at four.
- A rent roll is a dated, unit-level list of tenants, rents, and lease terms. It has to tie to leases, a trailing operating statement, and bank deposits.
- Five units is where many lenders stop using the simple rent-over-payment test and start looking at net operating income.
- Reserves commonly run about 6 months of the full monthly payment. Conservative rate-and-term files under $1,500,000 can see them waived, and loans above that size typically step up to about 9 months.
- Reserves sit on top of your down payment and closing costs. Plan the cash accordingly.
- Purchase leverage on investment property typically lands at 75%–80% LTV, subject to lender guidelines.

Why Five Units Changes the File
Five units moves a building from the residential side of lending to the commercial side. LoopNet notes that a property with five or more units is treated as commercial real estate. It adds that underwriting there focuses on property income, debt coverage, and rent-roll quality rather than the borrower’s personal finances.
That matters because the simple DSCR formula you learned for duplexes does not always carry over. DSCR is the debt service coverage ratio: how well the building’s income covers its debt. On one to four units, most programs divide gross monthly rent by PITIA. PITIA is principal, interest, taxes, insurance, and association dues. At five units, some lenders instead divide net operating income (NOI) by annual debt service. NOI is rental income minus operating expenses.
| Factor | 1–4 Units | 5+ Units |
|---|---|---|
| Income measure | Rent ÷ PITIA | Often NOI ÷ debt service |
| Expenses | Mostly outside the test | Counted in NOI |
| Appraisal | Rent schedule or small income report | Commercial-style income appraisal |
| Key documents | Lease, appraisal rent | Rent roll, T-12, leases |
The same building can produce two different coverage numbers. A modeled building might read around 1.25x on a gross-rent test and near 1.05x once vacancy, management, repairs, and common-area utilities come out. Same building, different answer. Which test applies is a program choice, so you ask before you write an offer.
Not every lender in the wholesale network takes five units. A subset does, and they differ on income method, leverage, and paperwork. Your first question is whether the program reaches the unit count. Everything else follows from that.
What Goes Into a DSCR Rent Roll?
A strong rent roll is a unit-level export with the date it was run. Tilt Analytics says it should list each unit, the tenant, lease start and end dates, contract rent, market rent, deposits, concessions, and delinquency. A summary page does not count.
Here is how five units with mixed status typically get treated:
| Unit Status | What the Lender Sees | Typical Treatment |
|---|---|---|
| Leased, current | Signed lease, rent in deposits | Counted at lease or market rent |
| Leased, above market | Lease exceeds appraiser’s view | Often capped at market rent |
| Leased, below market | Lease under market | Lease rent usually drives it |
| Month-to-month | No term protection | Scrutinized, sometimes haircut |
| Vacant | No income | Zero, or market rent if allowed |
Treat those as common conventions, not universal rules. Programs differ, and the point of asking early is to learn the convention before you price the deal.
The other half of the file is the T-12, the trailing 12-month operating statement. It shows actual income and expenses month by month. Tilt Analytics calls the rent roll and T-12 the two documents every multifamily underwriting starts from. Expect the lender to want tax bills, insurance, and utility records too.
Does the Rent Roll Have to Tie Out?
Yes. The rent roll multiplied by 12 should roughly match the T-12’s income. Wheelbarrow Profits treats a gap of more than 5% as a flag for vacancy, concessions, bad debt, or a stale roll. ProPrise makes the same point and adds a warning: property managers produce rent rolls, and rolls can be shaped, especially near a sale.
So you test it. Build the reconciliation in this order:
1. Match each lease to its line on the roll.
2. Match the roll’s monthly total to the T-12’s collected income.
3. Match collected income to actual bank deposits.
4. Confirm deposits and concessions against the leases.
The seller’s pro forma is a marketing document. Treat it that way. A roll that does not match deposits is the most common source of rework on a five-unit file. (Lenders find these mismatches faster than buyers do.)
Lendmire’s piece How to Build a DSCR Rent Roll When Buying Rentals From a Landlord covers the seller-side requests in more detail.
Which Rent Counts?
Rent that is in place and documented counts most. A common convention credits the lower of the lease rent and the appraiser’s market rent, unit by unit. If a lease sits above market, the extra often does not help you. If a lease sits below market, the lease usually controls.
Vacant units either contribute nothing or get credited at market rent, depending on the program. Some programs cap how many vacant units can exist at closing. Month-to-month tenants are the softer part of any roll. A market source’s rent roll guide flags heavy month-to-month concentration as a red flag.
Rent-controlled or below-market units work the same way: the lease drives the number, so the file can look weaker than a market-rent view.
Worth a note: the 1007 form is the single-family rent schedule, and the 1025 is the small income property report for two to four units. A five-unit building sits outside the 1025’s scope, so appraisers commonly use a commercial-style income approach. The program names the product.
How Does Underwriting Walk Through a Five-Unit File?
Step by step, the sequence looks like this:
1. Eligibility. Confirm the program reaches five units and whether it measures gross rent or NOI.
2. Documents. Collect the rent roll, leases, T-12, and expense records.
3. Reconciliation. Tie the roll to the T-12 and deposits.
4. Income rule. The program turns that data into a qualifying figure. Under an NOI method, that means income less vacancy and expenses.
5. Coverage test. The ratio gets compared against the program’s floor.
6. Appraisal. The income appraisal confirms market rent and value.
7. Reserves. The lender checks your post-closing liquidity.
On coverage, 1.00 is where many select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and higher leverage.
One caution. Clearing 1.00 is not the same as positive cash flow. DSCR compares income to the payment. Repairs, vacancy, management, utilities, and capital expenses sit outside a gross-rent test, and they are expensive at five units. Run your own operating budget separately.
How Much Do Reserves Run at Five Units?
Most programs we place files with want about 6 months of PITIA in liquid assets after closing. That is the commonly cited figure, but it moves. Conservative rate-and-term refinances at modest leverage under $1,500,000 can see reserves waived. Loans above $1,500,000 typically step up to about 9 months. Loan size, leverage, and transaction type all push the requirement up or down.
Two points keep people from miscounting.
First, the months multiply the full payment, not the rent and not just principal and interest. Six months means six times the complete PITIA. Know that number before you tour the building.
Second, reserves are separate cash. They do not replace the down payment or closing costs. If you bring 20% down and need six months of reserves, you need both. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
What counts as an asset varies. Checking, savings, and brokerage balances are the plain cases. Some lenders count only a portion of retirement balances. Ask which assets your program accepts before you move money around, because a transfer can create its own paperwork.
Reserves are also not set by any federal rule. They are lender and investor overlays. That is why one program asks for more than another at the same leverage.
Here is a point worth thinking out loud about. A weak roll does not usually raise the reserve months directly. It tends to cost you leverage, or push the file to a different lender, which then changes the reserve ask. So a messy roll can show up as a bigger cash requirement indirectly. That makes the rent roll a cash-planning issue, not just a paperwork issue.
Lender reserves are also not your repair budget. Lease-up costs, deferred maintenance, and turnover come out of pocket on top of lender-required liquidity. Budget them separately.
DSCR vs. conventional financing
There are two common ways to finance an investment property, and they qualify you differently — here’s how investors weigh them.
Why investors choose it
- Qualifies on the property’s rental income — no personal tax returns, W-2s, or pay stubs needed to document income.
- No personal debt-to-income ceiling to clear, so existing mortgages and obligations don’t cap your borrowing the same way.
- Can be closed in an LLC, keeping the property inside a business entity.
- Built for scaling — not held to the limit on number of financed properties that conventional financing applies.
- Underwriting centers on the deal: generally qualifies when the rent covers the payment, a 1.00x coverage ratio being a common baseline (confirmed in underwriting).
- Designed specifically for investment property, including long-term and, where the program allows, short-term rentals.
Where it’s strong
- Often the lowest ongoing financing cost for a buyer who fully qualifies on personal income — a fit for a first property or a cost-first purchase.
Trade-offs for investors
- Requires full personal income documentation and must fit within a debt-to-income limit — salary, existing debts, and other mortgages all count.
- Typically held in your personal name rather than a business entity.
- Caps how many financed properties you can carry, which can become a ceiling as a portfolio grows.
- Evaluates you as a borrower as much as the property, which usually means more paperwork.
How investors usually choose: a first or single property often optimizes for the lowest financing cost; portfolio builders often optimize for leverage, vesting in an LLC, and scaling past conventional caps. The right answer depends on your goals, the property, and current guidelines — both paths run through select lenders in Lendmire’s wholesale network, with eligibility and terms confirmed in underwriting.
Leverage, Credit, and Loan Size on a Five-Unit Purchase
On an investment-property purchase, most files land at 75%–80% LTV (20%–25% down), subject to lender guidelines. LTV is the loan amount divided by the property value. On a cash-out refinance of a standard rental, leverage tops out around 75% LTV across most of the network.
A larger down payment lowers the payment and can lift the coverage ratio. It never erases credit floors, reserve rules, or property eligibility. The strongest files clear both tests: enough equity and enough rental coverage.
On credit, a 620 floor exists in parts of the network. Most programs want around 660, and 700 or better unlocks the strongest leverage tiers. Standard programs run up to $3,000,000, and above $2,500,000 the network generally holds to 30-year fixed structures. Interest-only periods and extended terms are available through select lenders.
Lenders also review the property itself. Mixed-use buildings with commercial space can fall outside a residential-multifamily program and may need a different loan product. Manufactured homes, log homes, and barndominiums are not offered in these programs.
DSCR loans are designed for non-owner-occupied investment properties. Because they are business-purpose investor loans, they are reviewed differently from a standard owner-occupied mortgage; the CFPB’s Regulation Z exempts business-purpose credit from its consumer rules. That exemption does not make a five-unit building a one-to-four unit property. Underwriting still treats it as commercial in character. Entity vesting, such as buying in an LLC, depends on program terms.
Mistakes That Cost Investors Money
Most trouble comes from a handful of assumptions.
- Using the duplex formula on a five-unit building. Model it both ways before you offer.
- Trusting the seller’s roll. Verify against leases and deposits.
- Counting above-market lease rent. Many programs cap it.
- Forgetting reserves. They are separate from the down payment.
- Assuming 1.00 means cash flow. It does not.
- Skipping the unit-count question. Ask which programs reach five units before you pick a lender.
If you already own a five-unit building and are thinking about pulling equity, Lendmire’s article Investor Cash-Out Refinance Requirements on a 5+ Unit Building covers that side. For the full program picture, the complete DSCR loans guide is the place to start.
Key Terms Defined
Rent roll: a dated, unit-by-unit list of tenants, rents, lease dates, and deposits.
T-12: the trailing 12-month operating statement showing actual income and expenses by month.
NOI (net operating income): rental income minus operating expenses, before debt payments.
PITIA: principal, interest, taxes, insurance, and association dues, the full monthly obligation.
Reserves: liquid funds you hold after closing, counted in months of PITIA.
LTV: loan-to-value, the loan amount as a percentage of the property’s value.
Frequently Asked Questions
Is a five-unit building residential or commercial?
Commercial, in underwriting terms. LoopNet describes five or more units as commercial real estate. That is why the file leans on the building’s income, and why many lenders use NOI-based coverage rather than rent over PITIA.
Does the lender use my lease rents or the appraiser’s rents?
Often the lower of the two, applied unit by unit. That is a program convention, not a universal rule. Leases above market usually do not raise your qualifying income, while below-market leases typically count at lease rent.
How are vacant units counted?
They usually add nothing to qualifying income, or they are credited at market rent if the program allows it. Some programs also limit how many units can be vacant at closing. Ask the program before you buy a partly empty building.
What do reserves multiply?
The full monthly PITIA. Many files need about 6 months, conservative rate-and-term loans at modest leverage under $1,500,000 can see reserves waived, and loans above that size typically step up to about 9 months. Reserves are separate from your down payment and closing costs.
What if the seller’s rent roll does not match the leases?
Fix it before you rely on it. Reconcile the roll to leases, the T-12, and bank deposits. A gap of more than 5% is a standard warning sign per Wheelbarrow Profits. Unresolved mismatches can cost you leverage or force a different lender.
