The Quick Read: Not directly: the offer letter does not change how much you can borrow, because this line qualifies primarily on property-level rental income covering the payment, subject to lender guidelines, and your future paycheck is never calculated. The limit comes from equity, rent coverage, credit score, and the program’s line-size caps.
- Second lien (you keep your first mortgage): combined loan-to-value up to 70% at a 720 score or better, on lines from $50,000 to $500,000, on an investment property.
- First lien (a rental with no mortgage): loan-to-value up to 75% at 740 or better and 70% from 700 to 739 on lines to $500,000. Larger lines, up to $1,000,000, top out at 65%.
- Rent test: gross monthly rent must cover a stress payment on the entire line at 1.10x or better.
- Availability: offered through select programs in 15 of Lendmire’s 16 licensed states, every licensed state except Tennessee, and always subject to underwriting.
Key Terms Defined
A few terms come up in every conversation about this product, so here they are in plain words.
- DSCR (debt service coverage ratio): gross monthly rent divided by the monthly payment the lender uses to test the loan. A result of 1.10x means rent is 110% of that payment.
- DSCR HELOC: a revolving line of credit on a non-owner-occupied one-to-four-unit rental, qualified on the rent instead of your personal income.
- Second lien: a line that sits behind a first mortgage you keep in place.
- First lien: a line in first position, available only on a rental with no mortgage.
- CLTV (combined loan-to-value): your first mortgage balance plus the new line, divided by the property’s value.
- Draw period: the stretch when you can borrow from the line and pay interest only on what you have drawn.
- Offer letter: a signed note from an employer stating pay and a start date. It matters on income-based loans because it can stand in for a pay stub.
- Seasoning: the waiting period a lender wants after you buy or refinance a property before you borrow against it.
What Actually Sets the Size of the Line?
Four things set the cap: the equity in the rental, how well the rent covers the stress payment, your credit tier, and the program’s line-size limits. Your job status is not on that list. Across the wholesale network Lendmire works with, this line is built to look at the property, not at your pay.
Think of it as four gates. The line has to clear all of them, and the smallest result wins.
1. Leverage gate. The program caps total debt as a percentage of value. On a second lien that cap is 70% CLTV, and it requires a 720 score or better.
2. Rent gate. The rent has to clear 1.10x against a stress payment on the full credit limit.
3. Size gate. Lines run from $50,000 up to $500,000 on a second lien. A first lien can run to $1,000,000, at a lower loan-to-value on the larger lines.
4. Credit gate. A second lien needs a 720 score. A first lien needs 700.
A bigger salary opens none of these gates wider. A job gap closes none of them. That is the whole reason the offer letter is a non-factor for sizing.
A Worked Sizing Example
Here is the sizing logic with illustrative percentages. Treat these as modeled assumptions, not a quote or an approval.
Say you own a rental worth 100% of its appraised value. Your first mortgage balance is 45% of that value, and your score is 720 or better.
- Step one: the program ceiling is 70% CLTV.
- Step two: subtract the first mortgage at 45%. That leaves room for a line worth 25% of the property’s value.
- Step three: check the line-size limits. The line must be at least $50,000 and no more than $500,000 on a second lien.
- Step four: test the rent against a stress payment on the full 25% line. If rent falls short of 1.10x, the line shrinks until it clears.
Now run a different borrower. Their first mortgage sits at 60% of value, so the leverage gate leaves only 10% of value. If that slice is under $50,000, there is no line at all. Equity, not income, is the constraint.
Next, take an owner with no mortgage and a 740 score. A first lien can reach 75% LTV on a line up to $500,000. Drop that score to the 700 to 739 band and the ceiling falls to 70%. Go above $500,000, up to $1,000,000, and the ceiling is 65% at a 720 score or better. These specifics are subject to lender guidelines and a full review of property, leverage, and credit.
One more adjustment: a declining-market flag on the property can lower the ceiling by 5 points. Always confirm which tier the file lands in.
How the Rent Test Can Shrink the Line
The lender does not test rent against what you would pay on the first day. It tests rent against a fully amortizing principal-and-interest payment on the entire credit limit, at the start rate plus 2 percentage points.
That means an unused line still counts in full. It also means a bigger line demands more rent. Taxes and insurance are not part of the qualifying payment on this program, which keeps the test focused on the line itself.
Rent is the lesser of the appraisal’s market rent and the lease, unless three months of receipts support a lease above market. A lease in place is required. On a two-to-four-unit building, at most one unit can be vacant.
On a second lien, confirm on the file how the lender treats the first-mortgage payment. The lender’s own coverage calculation governs, and the arithmetic here is illustrative only.
When rent is the constraint, the usual fix is a smaller line, not a different borrower. That is a rent-coverage decision, and the offer letter plays no part in it.
DSCR HELOC vs. an Income-Based HELOC
An income-based HELOC on a rental sizes the line against your pay and your debts. A DSCR HELOC sizes it against the property. Here is how the two compare, with the income-based column describing that product’s typical rules, not this program’s.
| Factor | DSCR HELOC | Income-based HELOC |
|---|---|---|
| What qualifies the line | Rent coverage | Personal income and debts |
| Offer letter | Not part of sizing | Typically reviewed as income |
| Tax returns, W-2s, pay stubs | Not calculated | Typically requested |
| Title in an LLC | Allowed on this program | Varies by lender |
| What caps the amount | CLTV, rent test, credit, line size | Income ratios plus equity |
If you want the broader comparison of how rent-qualified and income-qualified loans differ, the complete DSCR loans guide covers it.
What Job Timing Does to the Line
The table below walks through the common job-transition situations. In each one, the line size comes from the same four gates.
| Situation | Effect on line size | What still matters |
|---|---|---|
| Offer signed, start date ahead | None | Equity, rent, credit |
| Started, no pay stub yet | None | Same four gates |
| Job lost after closing | Line stays as written | Payment on drawn balance continues |
| Relocating for the job | None, if you keep the rental | Rental must stay non-owner-occupied |
The third row deserves a plain warning. The line does not reprice itself to your income, and neither does your obligation. The draw period is five years of interest-only payments on the drawn balance, followed by a 25-year repayment period with a 30-year maturity. The rate is variable.
At least 80% of the line is drawn at closing, so you carry a real balance from the start. The members of an LLC sign as guarantors. If a new job slips or falls through, the debt is still yours.
Where the Offer Letter Does Matter
The offer letter matters on any loan that counts your personal income. That includes a purchase mortgage on the home you are moving into and a HELOC on a home you live in. Large retail lenders use employment history and pay in those files, and start-date rules vary by lender and loan type. Those are separate products with their own tests, and a DSCR HELOC is never offered on an owner-occupied home.
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 Federal Register notice on the ability-to-repay rule explains that investment-purpose loans fall in the business-purpose category outside that rule.
The line that matters is occupancy. If you plan to live in the rental within the coming year, the business-purpose analysis can change. Under the CFPB’s Regulation Z text, credit to acquire counts as business-purpose in that case only on properties with more than two units. Credit to improve or maintain counts only above four units. A one-to-two-unit property you will live in is treated as consumer credit, and income documentation, possibly including that offer letter, comes back.
Business purpose also does not mean free of rules. A Hunton Andrews Kurth publication on business-purpose lending warns that some states require licensure for loans secured by residential real property, whether consumer or business purpose. That is one reason this program is offered only where Lendmire holds consumer licenses.
What the File Looks Like
The file is about the property and your credit. It does not include a pay stub, W-2, tax return, debt-to-income ratio, or offer letter. A short checklist:
- A lease in place and a rent schedule from the appraiser.
- Your credit report. The lender’s own pull sets your tier.
- Proof of title and hazard insurance covering both liens, with flood coverage where required.
- Entity documents if the rental is vested in an LLC.
- A valuation, covered below.
LLC vesting is allowed on investment property, subject to lender program eligibility. The members sign as guarantors. A title holder who is not a borrower signs a non-borrowing owner acknowledgment and the security instrument. The borrowers on the line need not be the borrowers on the first mortgage.
Valuation. Lines to $400,000 use an automated valuation with a confidence score of 85 or better, paired with a property inspection report, or a full interior appraisal. Lines above $400,000 take a full interior appraisal on Form 1004, 1073, or 1025. Appraisal waivers are not accepted.
Credit history. Expect no 30-day mortgage late in the last 12 months. Expect 48 months since a bankruptcy, foreclosure, short sale, or deed-in-lieu. No reserves and no cash to close are required.
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).
Borrower and property. US citizens, permanent residents, and non-permanent residents with a Social Security number can borrow. Foreign nationals and ITIN borrowers are outside the program. Eligible properties include single-family homes, PUDs, townhomes, two-to-four-unit buildings, and condominiums, plus lots up to 10 acres. Rural-designated property, condotels, row homes, leaseholds, and mixed-use are outside it. So are properties listed for sale in the prior two months and properties with a solar lien. Each borrower is limited to 5 loans or $2,500,000 with the program.
Sequence It Before the Move
Open the line while the rental’s numbers are simple. This product is never closed together with a purchase, so it has to exist before the next deal goes under contract. If the plan is to use the equity as a down payment on another rental, the line comes first and the contract comes later.
Check four things before you start:
1. Confirm the six-month clocks on title and the last note date.
2. Confirm the rental is not listed for sale and will stay non-owner-occupied.
3. Confirm any first mortgage allows a junior lien. This matters most when the first mortgage is itself a DSCR loan.
4. Decide how much of the line you actually need, since the whole limit is tested for rent coverage.
Then think about cash flow in the gap. Interest-only payments on a drawn balance are modest in structure but real in practice. Budget for them with the new paycheck in mind, even though the lender never asks about it.
Common Mistakes
- Assuming the letter boosts the line. It does not. Equity and rent set the amount.
- Skipping the full-line stress test. A bigger limit demands more rent coverage, even if you plan to draw little. The program requires at least 80% drawn at closing anyway.
- Treating a first mortgage as irrelevant. A first mortgage you keep limits you to a second lien, and a second lien needs a 720 score.
- Planning to live in the rental. Owner occupancy changes the product and the rules.
- Using a listed or just-bought property. The seasoning clocks and the listing rule can disqualify an otherwise strong rental.
Frequently Asked Questions
Does a DSCR HELOC lender ask for an offer letter?
The offer letter is not part of how the line is sized, because personal income is not calculated on this program. The lender’s file list for your specific scenario governs what documents are collected. Expect the file to center on the lease, the credit report, title, insurance, and the valuation.
Can I qualify if I am between jobs but have strong credit and equity?
A job gap does not enter the sizing, and credit and equity still do. A second lien needs a 720 score and a first lien needs 700, subject to underwriting. Keep in mind that the payment on your drawn balance continues regardless of your paycheck.
Why would my line come in below 70% of value minus my mortgage?
Four things can pull it lower. The rent may fail the 1.10x test on a full-line stress payment. The program’s line-size caps may bind. A declining-market flag can lower the ceiling by 5 points. Smaller leverage tiers also apply to first liens at lower scores.
Can my LLC hold title to the rental?
Yes, subject to program terms, on investment property.
Can I use the line on the home I am moving into?
No. This line is secured only by a non-owner-occupied rental, never your own home or a second home. A line on a home you live in is a different product that does use your income and employment.
