The Quick Read: Usually the lender counts the lesser of the appraiser’s market rent and your signed lease, so a raise helps only until it reaches market rent, unless three months of rent receipts support a lease above market.
- A raise helps most when your old rent sat below market and the new lease lands at or under market.
- A lease above market needs three months of rent receipts to count in full, subject to underwriting.
- The lender tests the rent against a stress payment on the entire credit limit, not just the drawn balance.
- A signed lease must be in place, and a 2-4 unit property may have at most 1 vacant unit.
- Raising rent after the appraisal is ordered does not change the appraiser’s opinion.
How Does a Rent Increase Change the Coverage Number?
A higher counted rent lifts your coverage ratio, and the ratio is what qualifies the line. The test divides gross monthly rent by a qualifying payment. Across the wholesale network Lendmire works with, the program minimum is typically 1.10x, subject to underwriting.
The qualifying payment is a fully amortizing payment on the entire credit limit, run at a stress rate above the start rate. Taxes and insurance are not part of it. A bigger line means a bigger qualifying payment, so the counted rent has to cover more.
Your personal income is never calculated. The property qualifies primarily on rental income covering the payment, subject to lender guidelines. The line is a standalone second lien behind your first mortgage, or a standalone first lien on a paid-off rental. An LLC can stay on title.
Which Rent Counts: The Lease or the Appraiser’s Number?
The appraiser documents market rent on a standard rent schedule form, which a lender uses to get an independent rent opinion on a one-unit rental. Two-to-four-unit properties use a companion form.
Agencies do not govern DSCR lines. The form just gives the lender a market-rent opinion built from comparable rentals. How that opinion gets used is a program choice, not a regulation.
Across the programs Lendmire places files with, the treatment is one rule with one exception, and the exception is the three months of receipts. Appraisers document market rent. The lender decides how income counts.
What Happens in Each Rent Scenario?
Your counted rent depends on where the new lease lands against market. This table shows the usual treatment, always subject to underwriting.
| Situation | Rent counted | What to document |
|---|---|---|
| Old rent below market, new lease at market | The new lease | Signed lease, proof tenant pays it |
| New lease below market | The lease | Signed lease |
| New lease above market | Market rent, or the lease with receipts | Three months of rent receipts |
| Increase announced, lease not signed | Not counted yet | Signed lease first |
| Month-to-month or expired lease | Generally market rent | Prior lease as support |
| Vacant rental | Does not fit this line | A lease must be in place |
Notice the second row. A discounted lease signed just before the appraisal can pull the counted rent down. Sign at market, not under it.
Does Timing Matter Against the Appraisal?
Yes. The appraisal captures market rent as of its date. Raising rent after the appraisal is ordered does not move the appraiser’s opinion.
Sequence it this way. Raise the rent with proper notice, or offer a renewal if the lease is expiring. Wait for the term to roll if the tenant is mid-lease. Sign the new lease and collect proof of payment. Then apply and order the valuation.
For lines up to $400,000, the valuation is an automated valuation with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal. Appraisal waivers are not accepted. Hand the appraiser your lease, a rent roll if the property has several units, dated improvements and any comparable rentals you know of.

What About a Lease Above Market Rent?
A lease above market can still count in full when three months of rent receipts support it. Without receipts, the appraisal’s market rent is the number the lender uses.
Say your tenant signs a renewal well above what comparable rentals show, and the first payment has not even arrived. The lender has no proof the tenant pays that figure. Wait for three months of receipts, or plan the file around market rent.
Treat a related-party tenant differently. Expect market rent and closer review. A government-subsidized tenant is usually supported with the housing contract, the lease and the appraisal.
Does a Rent Increase Change Equity or CLTV?
No, not directly. Equity is tested separately from rent. Combined loan-to-value (CLTV) is your first-mortgage balance plus the new line, divided by the property’s value. A rent increase affects CLTV only if the valuation reaches a higher value.
Leverage on a second lien runs up to 70% CLTV at a 720 credit score or better, on lines from $50,000 up to $500,000. On a first lien, a rental with no mortgage, leverage is measured as loan-to-value (LTV) and runs up to 75% LTV at 740 or better, and 70% LTV from 700 to 739, on lines up to $500,000. For first-lien lines above $500,000, up to $1,000,000, the ceiling is 65% LTV at 720 or better. These are ceilings through select programs, subject to underwriting. Each figure is subject to lender guidelines and a complete review of property type, leverage, and credit.
A rent raise strengthens the coverage test. It does not buy you more leverage.
What Does the Rest of the File Look Like?
Beyond the rent, the line has fixed mechanics that shape your decision. At least 80% of the line is drawn at closing, and later draws are at least $5,000 each. The draw period is 5 years interest-only on the drawn balance, followed by a 25-year repayment period and a 30-year maturity.
The rate is variable. That matters, because the CFPB notes that HELOC payments can change from month to month and are often significantly higher once repayment begins. Passing the coverage test is a qualifying hurdle, not a cash-flow forecast. Stress-test your own numbers beyond the ratio.
Other file items:
- Credit: 720 minimum on a second lien, 700 on a first lien, with no 30-day mortgage late in the last 12 months.
- Seasoning: a rental bought or refinanced inside the last 6 months is not eligible (that clock runs from the last note date to the new note date), and the owner must have held title for 6 months (settlement date to note date).
- No reserves are required, and exposure tops out at 5 loans or $2,500,000 per borrower with the program.
- Not eligible: rural-designated property, condotels, row homes and leaseholds.
The full structure is laid out in the complete DSCR loans guide.
The Raise-or-Wait Decision
A rent raise can improve the ratio, but it also risks turnover and a vacancy, and a vacant rental does not fit this line until it is leased.
Raising to market makes sense when your current lease sits clearly below market. The counted rent rises, and the new lease is easy to document. Pushing past market adds nothing to the counted figure unless you wait for receipts.
Coverage and sequencing are the whole game. Compare your lease with likely market rent before you apply, and avoid a lease so generous it drops the ratio under the minimum once the valuation lands.
Short-term rentals work differently. Nightly rate times 30 is not valid market-rent support, and the rent schedule documents monthly rent. Short-term rental rules can vary by city, county, HOA, and property type, so investors should confirm local rules before relying on projected rental income. Rent-regulated units may also limit legal increases, so raising to market may not be allowed.
Key Terms Defined
DSCR (debt service coverage ratio): gross monthly rent divided by the qualifying payment.
Qualifying payment: the stress payment, principal and interest on the whole credit limit, used only to test coverage.
Market rent: the appraiser’s opinion of what comparable rentals bring each month.
CLTV: first-mortgage balance plus the new line, divided by the property’s value.
Draw period: the stretch when you can borrow from the line, interest-only on the drawn balance.
Seasoning: the waiting period after a purchase or refinance before the line is available.
Frequently Asked Questions
Does a recent rent increase count right away?
Only once it is a signed lease with proof the tenant pays it. An announced increase with no signed lease does not count. Then the lease is compared with market rent, and the lesser figure generally governs, subject to underwriting, unless three months of rent receipts support a lease above market.
What if the appraiser’s market rent comes in below my new lease?
Market rent generally becomes the counted number. The exception is a lease above market supported by three months of rent receipts. If you cannot wait for receipts, the file runs on market rent, so check whether the ratio still clears the minimum.
How soon after buying or refinancing can I use this line?
Two six-month clocks apply: the line is not available on a rental bought or refinanced in the last 6 months (last note date to new note date), and title must have been held for 6 months (settlement date to note date). Both are subject to underwriting.
Does a rent increase on one unit help a duplex or fourplex?
It helps once documented, though the comparison runs unit by unit against the rent roll. A two-to-four-unit property may have at most 1 vacant unit, so a vacancy can matter as much as a raise.
