The Quick Read: Break-even is the total cost of the new loan, including any prepayment penalty on your existing first mortgage and any second lien you must pay off, divided by your monthly principal-and-interest savings, and you then compare the answer to how long you will realistically hold the property.
- Count the prepayment penalty on the old first lien as a real cost line.
- Measure savings on principal and interest only, because taxes and insurance do not change with a refinance.
- Any second lien behind your first usually has to be paid off or subordinated before the new first can close.
- A cash-out refinance often raises the payment, so judge it by what the cash earns, not by payment savings.
- Clearing the DSCR test on the new balance is a separate gate from clearing break-even. You need both.
Key Terms Defined
DSCR (debt service coverage ratio): the property’s monthly rent divided by its monthly PITIA, which is principal, interest, taxes, insurance, and any association dues.
First lien: the mortgage with top priority on the property. It gets paid first if the property is sold or foreclosed.
Junior lien: any loan recorded behind the first, such as a second mortgage or a home equity line.
Payoff statement: the lender’s written figure for what it takes to retire a loan on a given date, including per-day interest.
Break-even months: total refinance cost divided by monthly savings. It is the point where the refinance has paid for itself.
Subordination: a junior lender’s written agreement to stay behind a new first lien. It needs their consent, and they have no obligation to give it.
Seasoning: the time you must own or hold a loan before a lender will refinance it. About six months is the common expectation for a cash-out.

What Holding a First Lien Changes
The first lien is the loan you are replacing, so its terms feed straight into your cost. A penalty on that loan raises your cost. A second lien behind it adds a payoff or a consent request. What happens depends on the refinance type.
| Refinance type | Old first lien | Any second lien |
|---|---|---|
| Rate-and-term | Paid off and released | Paid off or subordinated |
| Cash-out | Paid off, whole balance repriced | Paid off from proceeds, usually |
| Keep first, add second | Stays in place | New second sits behind it |
The third row matters because it avoids repricing a cheap first loan. Lendmire’s piece Cash-Out Refinance vs Investment HELOC When You Have a Low First Lien covers that choice in depth. Here, the math below treats it as one of three paths you can price side by side.
The Step-by-Step Calculation
Run these steps in order. Each one feeds the next.
1. Pull the payoff statement on your existing first. Get the exact balance, the per-day interest, and any prepayment penalty from the note. The penalty is charged on the balance at payoff, and in the early years that balance has barely moved.
2. Total the refinance cost. Add the new loan’s lender fees, appraisal, title, and recording. Add the prepayment penalty. Add any second-lien payoff costs and any local transfer or mortgage recording taxes. Prepaid interest and escrow deposits are cash you need at closing, but they are not cost in the break-even sense. Treat them as liquidity.
3. Compute monthly savings on principal and interest only. Subtract the new principal-and-interest payment from the old one. Leave out taxes and insurance, because a refinance does not change them. Use the new balance, including rolled-in costs and any cash-out, and the new term.
4. Divide total cost by monthly savings. The result is break-even in months.
5. Compare to your realistic hold period. Break-even only pays off if you hold past it. Sell or refinance again sooner, and you lose money. Every month after break-even is savings.
6. Check the DSCR on the new loan. For one-to-four-unit rentals, the lender divides rent used for lender review by the new PITIA. The appraiser documents market rent on form 1007 for a single-family home or form 1025 for a two-to-four-unit property. Larger multifamily and commercial properties generally use net operating income divided by annual debt service instead.
Step six is where many refinances stall. In Lendmire’s network, 1.00 is where many select programs start, and a separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage. Your old loan’s payment is irrelevant to the new test. Only the new payment counts.
One caution on reading the result. Clearing 1.00 does not mean positive cash flow. Repairs, vacancy, management, utilities, and capital expenses all sit outside the ratio.
Worked Example 1: Rate-and-Term Refinance
These figures are indexed units, not dollars, and they are modeled assumptions for illustration only. They are not market data.
- Closing costs on the new loan: 10 units.
- Prepayment penalty on the old first: 6 units.
- Second lien: none.
- Total cost: 16 units.
- Monthly principal-and-interest savings: 0.8 units.
Break-even is 16 ÷ 0.8 = 20 months. Hold the property 36 months and you keep 16 months of savings, which is 12.8 units. Hold it 14 months and you lose about 4.8 units, because you stopped before break-even.
Now add the second gate. Say rent is 140 units and the new PITIA is 100 units. Coverage is 1.40x, comfortably above where select programs start. Both tests pass. Reserves still apply, commonly around six months of PITIA, though conservative rate-and-term files at modest leverage under $1,500,000 can see them waived. Reserve rules vary by lender, leverage, and loan size.
Worked Example 2: Cash-Out on a Cheap First Lien
A cash-out reprices the entire balance, not just the new cash. That is the cost people miss when the old first lien is a good one.
Keep the same indexed units. Rent is 140. The old PITIA is 100, so coverage is 1.40x. You take out 100 units of cash. The new PITIA rises to 122, so coverage drops to about 1.15x. Rent did not move, but the denominator grew.
Monthly savings here are negative. The payment went up by 22 units, so break-even in the usual sense does not exist. Use a different test instead. Compare the added annual payment to the cash you pulled. The added annual cost is 22 × 12 = 264 units on the PITIA line, though the actual principal-and-interest bump is what you would measure in a real file. Use that same logic: divide the added annual principal-and-interest by the cash taken. The result is a rough hurdle rate the cash must beat.
That hurdle overstates the true cost, because part of every payment repays principal, which is your own equity coming back. It still tells you something useful. If the cash goes into a next purchase, a renovation, or another asset, ask whether it can earn more than the hurdle after its own risks and costs.
Cash-out leverage tops out around 75% LTV on an investment property across most of the network, subject to lender guidelines. Short-term-rental collateral generally sits lower, around 70% on a cash-out. Seasoning of about six months is the common expectation.
Worked Example 3: Keep the First, Add a Second
Same property, same rent of 140 units. You leave the old first alone, so there is no prepayment penalty and no repricing of the old balance. A new second lien adds a payment of 12 units on top of the existing 100. Combined obligation is 112 units, so combined coverage is 140 ÷ 112 = 1.25x.
The upfront cost of the second is 4 units. There is no payment savings to divide into it, so the test is the same hurdle idea as in example 2. Compare the second’s added cost to what the cash earns.
Whether this path is open depends on your first lien’s documents and on lender guidelines for second liens behind a first. Read your note and ask your servicer. Do not assume.
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.
Prepayment Penalty and Payoff Timing
The penalty is a contract term, so the note controls it. Common structures are step-down schedules, flat percentages, months of interest on a portion of the balance, and yield maintenance. They vary by lender, state, and entity type. A payoff through refinance is typically a trigger, along with a sale or a large principal paydown.
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 TILA exam procedures treat credit to acquire or improve non-owner-occupied rental property as business-purpose credit, and a law-firm paper from Hunton walks through the occupancy test behind that label. The practical takeaway is simple. Consumer-style penalty limits should not be your assumption, so read the clause.
Timing can move the answer, but waiting is not free. Suppose a step-down drops your penalty from 6 units to 3 after a year. Waiting trims total cost, but you give up a year of monthly savings. At 0.8 units a month, that forgone savings is 9.6 units, which is more than the 3 you save. In that case, waiting loses. Wait only when the penalty drop exceeds the savings you forgo.
Payoff figures also move. Per-day interest keeps accruing, and payoff statements expire. Ask for an updated figure close to closing and rerun the math with it. An escrow refund from the old lender is cash back, but it is not savings.
Junior Liens at Refinance
A refinance pays off and releases the old first mortgage. A second lien then has two options: get paid off, or agree in writing to stay behind the new first. Subordination needs the junior lender’s consent, and that lender can say no.
Plan on a payoff. Add the payoff to your cost, and add the balance to the new loan size. That can push a deal you thought was rate-and-term into a different category, depending on program rules. It also raises leverage, which has to fit within the caps.
Due-on-sale protections for junior liens are written around owner-occupied homes. A rental falls outside them, so the contract language controls. Titling matters too. Lien and credit-line options can differ when a rental sits in an LLC versus your personal name, subject to lender program eligibility.
Sensitivity: When to Rerun the Math
Using the base case from example 1, here is how break-even moves.
| Change | Total cost | Monthly savings | Break-even |
|---|---|---|---|
| Base case | 16 units | 0.8 | 20 months |
| Costs rise by 4 units | 20 units | 0.8 | 25 months |
| Savings fall to 0.6 | 16 units | 0.6 | about 27 months |
| Both worsen | 20 units | 0.6 | about 33 months |
Rerun the math when any of these happen:
- The payoff statement changes or expires.
- The appraisal comes in below expectations and the loan amount or leverage shifts.
- A second lien needs payoff and was not in your original estimate.
- You roll costs into the loan, which raises the balance and trims your savings.
- Your hold plan changes.
Term reset deserves its own check. Restarting a 30-year amortization lowers the payment, but a lower payment over thirty new years is not the same saving as a lower payment over the years you had left. Compare total interest over your hold, not only the monthly figure. Where select lenders offer extended terms or interest-only periods, savings and coverage change again, so price those separately.
Reading the Result
| Break-even vs. hold period | What it usually means |
|---|---|
| Well inside your hold | Likely worth pursuing, if the new DSCR clears |
| Close to your hold | Marginal. Small cost changes flip the answer |
| Beyond your hold | Usually not worth it on payment savings alone |
Some refinances make sense despite a long break-even. A BRRRR exit, a portfolio build, or a move from a short balloon to a stable term are about access to capital or risk, not payment savings. For those, use the cash-out hurdle test from example 2. Lendmire’s piece How a Refinance Break-Even Works: When the New Loan Pays for Itself covers the core payback logic in more detail.
When Not to Refinance
A refinance that looks good on the loan’s headline terms alone can fail once the penalty and junior-lien payoff are counted. Skip it, or wait, in these situations:
- Break-even is longer than the time you plan to hold.
- The penalty is large and a step-down is close, and the savings forgone by waiting are small.
- The new DSCR lands at or under the program minimum once costs roll into the balance.
- The old first is a cheap loan and you only need a modest amount of cash. A second lien may fit better.
- You are counting on payment savings that come entirely from a term reset.
Also avoid treating the DSCR result as proof the property pays for itself. Reserves, repairs, and vacancy still have to be funded.
Credit and loan size shape the options too. A 620 score floor exists in parts of the network, most programs want around 660, and 700 and up 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. Reserves commonly step up to about nine months above $1,500,000. Every file is underwritten individually, and the complete DSCR loans guide lays out the full picture.
Tax treatment can depend on how the funds are used and how the property is held; investors should keep clear records and speak with a qualified tax professional before relying on any deduction.
Frequently Asked Questions
Do I include taxes and insurance in the savings number?
No. Taxes and insurance do not change with a refinance, so they cancel out. Measure savings on principal and interest only. Taxes and insurance do matter for the DSCR test, because they are part of PITIA.
Does the prepayment penalty shrink as I pay down the loan?
Not meaningfully in the early years. The penalty is charged on the balance at payoff, and that balance barely moves at first. What shrinks it is time, if your note uses a step-down schedule. Check the note for the exact structure.
What if the savings are negative?
Then payment-based break-even does not apply. That usually means a cash-out or a larger balance. Judge it by what the cash earns against the added cost of carrying the larger loan, and confirm the new coverage still meets program minimums.
Can I keep my first lien and still pull cash?
Often, yes, through a second lien, subject to the first lien’s documents and lender guidelines. It avoids repricing the old balance. Compare the combined coverage and the second’s cost against a full cash-out.
Is there a standard break-even number I should aim for?
No. Rules of thumb vary and none are regulatory. Your hold period decides. A break-even inside your planned hold is the practical test.
