The Quick Read: Blended cost is the balance-weighted average cost of every debt you retire, compared against the all-in cost of the single new loan that replaces them. Calculate it by weighting each rate by its payoff balance, adding fees and exit costs to the new loan, and comparing both sides on the same principal. A lower headline number only counts if it survives fees, penalties, and a longer term.
- Weight every rate by its payoff balance. A simple average of the rates is wrong.
- Fold points, fees, and prepayment penalties into the new loan’s cost before you compare.
- Separate the refinanced debt from the fresh cash, because the new money has its own cost.
- Re-test coverage on the larger payment. Cash-out on a standard rental tops out around 75% LTV.
- Passing the coverage test does not mean the property cash flows. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Investors usually reach this question with a mixed pile of debt: a couple of mortgages, a hard-money note, maybe a line of credit or credit cards. One loan sounds cleaner. Whether it is cheaper is a math problem, and most people skip the math.

What Does “Blended Cost” Actually Mean?
Blended cost is the weighted average price of your existing debt, then the same measure for the new loan. A large balance counts for more than a small one. The formula fits on one line: add up each balance times its rate, then divide by the total balance.
Vaia’s explainer on weighted-average cost of debt frames it the same way: each debt’s share of the total, multiplied by its cost, then summed. Picture a stack where the first loan is 50% of the total payoff, the second is 30%, and the third is 20%. Your blended rate is 50% of the first rate, plus 30% of the second, plus 20% of the third. Use real shares that add to 100%.
A plain average gives a small credit-card balance the same vote as a large first mortgage. That is the core mistake the weighted method fixes.
Which Two “Blends” Are People Talking About?
There are two different comparisons, and they answer different questions.
Consolidation blend. You compare the weighted cost of all the loans you are paying off against the one new loan.
Keep-or-replace blend. You keep a low first lien and add new money through a line or second lien. You blend the old loan with the new money and compare that to one new cash-out loan. Lendmire’s piece Should a Scaling Investor Preserve a Low First Lien or Cash Out the Rental covers that version in depth.
This article walks through the first blend. The method carries over to the second.
How Do You Calculate It, Step by Step?
Work the numbers in this order. Every step uses figures you can pull from payoff statements and a lender’s fee sheet.
1. List every debt you are retiring. Use current payoff balances, not original loan amounts. Add accrued interest and payoff fees shown on each statement.
2. Compute the old blended rate. Multiply each payoff balance by its rate, add the results, and divide by total payoff. The sum of balance times rate is also your blended annual interest cost in dollars.
3. Price the new loan all-in. Take its annual interest on the full new balance, then add one-time costs: origination, points, appraisal, title, and any lender fees.
4. Add exit costs on the old loans. A prepayment penalty is a cost of leaving early, so it belongs in the comparison. So do hard-money exit fees and per-diem interest.
5. Spread the one-time costs over your expected hold. Divide total fees and penalties by the years you realistically keep the loan.
6. Compare on the same principal. Old stack: annual interest plus its share of exit costs. New loan: annual interest on the refinanced portion plus amortized fees.
7. Isolate the new money. Covered in the next section.
8. Re-test coverage. Covered after that.
One caution on step 3. Lenders do not itemize cost the same way. The CFPB’s closing-cost study found that origination fees are among the largest disclosed closing costs. It also notes that lenders differ in which costs they fold into the rate or origination charge and which they bill separately. A quote with no origination fee is not automatically cheaper. Compare totals, not line items.
How Do You Separate the Refinanced Debt From the Cash-Out?
Split the new loan into two buckets. The first bucket is the payoff of old debt. The second is the cash you receive, which is the new balance minus payoffs, costs, and reserves set aside at closing.
The refinanced bucket answers one question: is the same debt now cheaper? Compare it to the old blended cost.
The cash bucket answers another: what does the new money cost? Here is the method.
- Take the new loan’s total annual cost, including amortized fees.
- Subtract the old stack’s annual cost, including amortized exit costs.
- Divide the difference by the net cash you actually receive.
That is the incremental cost of the cash. Sometimes it is high, and that is fine if the cash buys something worth more. Sometimes the new loan lowers the cost of old debt and the cash comes nearly free. You cannot see either result in a single blended number.
Net proceeds are not the loan amount minus the old balances. Payoff, closing costs, required reserves, and any prepayment charge come out first, so a cash-out refi does not guarantee cash in hand.
Why Isn’t the Rate the Whole Answer?
Rate shows only the interest side. Three things change real cost: fees, exit penalties, and the term.
A cheaper loan on paper with heavy upfront costs can cost more over a short hold. A loan stretched across a fresh 30-year amortization can cost more in total interest, because the clock restarts. And payment savings alone do not equal break-even.
Investors often use break-even, which divides closing costs by monthly savings. Yahoo Finance’s walkthrough explains it and flags that a cash-out refinance distorts the math, because the larger balance raises the payment. For a consolidation, annual cost on the same principal is cleaner than payment-based break-even.
| Lens | What it measures | Best used for |
|---|---|---|
| Blended rate | Interest price per dollar of debt | First-pass screen |
| Blended rate plus amortized fees | Interest and one-time costs per year | Comparing offers |
| Payment change | Monthly cash demand | Coverage and cash-flow planning |
| Total interest over hold | Cost across the actual holding period | Term-reset decisions |
Interest-only structures widen the gap between the lenses. An interest-only payment can look light while the balance never shrinks. Select lenders in the network offer interest-only periods and 40-year terms, and those structures flatter the payment lens. Judge them on annual cost and total interest too.
What Mixed Debt Stacks Look Like
Most real stacks are not all mortgages, and each type has its own payoff quirks.
- First mortgages: check for a prepayment clock. A new cash-out starts a fresh clock on the new loan, so you may face two penalty clocks, the old one and the new one.
- Hard money: expect exit fees and per-diem interest on the payoff date.
- Second liens and lines: the new first-lien lender will generally require a junior lien to be paid off or subordinated.
- Credit cards and unsecured debt: the interest on these is often the highest in the stack, so the blended math can improve sharply. The tradeoff is that unsecured balances become debt secured by your property.
An investor who accepts a higher note rate to clear card debt and fund another purchase is doing a legitimate trade, as long as they see the whole cost. Rate alone is not the objective.
Does the New Loan Still Pass the Coverage Test?
A more affordable blended cost can still fail coverage. DSCR is monthly rent divided by the full monthly obligation: principal, interest, taxes, insurance, and any association dues. A bigger loan raises the payment and lowers the ratio.
Here is how that plays out across the network. The cash-out ceiling on a standard investment property is about 75% LTV, with about six months of ownership (seasoning) expected. Coverage of 1.00 is where select programs start. A separate select-lender path takes coverage below 1.00 with leverage and terms adjusted. Stronger ratios open better pricing and leverage. Final terms depend on lender guidelines, property type, leverage, and the borrower’s complete credit picture.
Credit matters too. A 620 floor exists in parts of the network, most programs want around 660, and 700+ unlocks the strongest leverage tiers. Reserves commonly run about six months of PITIA, stepping up to about nine months on loans above $1,500,000. Standard programs go up to $3,000,000. All of this is subject to lender guidelines, and every file is underwritten individually.
If coverage fails at the full cash-out size, you have options.
- Take less cash. A smaller balance means a smaller payment.
- Leave a low-cost loan in place and consolidate only the expensive debt.
- Choose a longer term or interest-only period through a select lender.
- Check whether the appraisal’s rent figure supports the ratio you modeled.
Two caveats matter here. First, DSCR compares rent to PITIA only. Clearing 1.00 does not mean the property produces positive cash flow, because repairs, vacancy, management, utilities, and capex sit outside the calculation. Second, an investor who consolidates and pushes the payment close to rent may pass the ratio and still feel squeezed.
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.
Single Loan or Several? The Cost Nobody Prices
Consolidating several properties into one loan can simplify servicing. It can also create a cost your spreadsheet will not show: flexibility. With cross-collateralized debt, selling one property can mean negotiating a partial release or paying down the pool. Program rules differ on how coverage is measured. Some programs blend rent and payments across the pool, while others underwrite each property. Ask which applies before you assume a strong property can carry a weak one.
Treat reduced flexibility as a real cost, and weigh it against the convenience. If you expect to sell one asset within a few years, separate loans may beat the pooled structure even if the pool’s headline cost is lower.
Where the General Rule Breaks
A few named situations flip the usual answer.
- A very low legacy first lien. When the cash draw is small, the old loan dominates the blend and keeping it usually wins. When the draw is large, the old loan is a small share and one new loan can make more sense.
- An old DSCR loan inside its penalty window. The refinance can erase the savings. Waiting may be cheaper.
- No-penalty options. A no-penalty structure usually exists, but lenders recover the cost somewhere else, in pricing or fees. No single number holds across the network.
- Amortization reset. A new 30-year note restarts the schedule, so a payment-based comparison can overstate savings.
- State law. State law, not federal law, generally sets the limit on prepayment fees for rental loans, so the answer can change by location.
Which Fees Map Into the Calculation?
Think of fees in three groups: lender charges (origination, points, underwriting, processing), third-party services (appraisal, title), and exit costs on the debt you retire. The CFPB’s Loan Estimate explainer is a useful category map for those groups. DSCR loans are business-purpose and exempt from that consumer disclosure form, so use it for categories only. Ask the lender for a fee sheet that covers the same items, and compare totals.
On tax: 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.
Key Terms Defined
Blended rate: the balance-weighted average of several loan rates, found by adding each balance times its rate and dividing by total balance.
Payoff balance: the amount needed today to retire a loan, including accrued interest and payoff fees.
Prepayment penalty: a fee for paying off a loan before a set period ends.
Seasoning: the waiting period between buying a property and cashing out equity, about six months on most programs.
PITIA: principal, interest, taxes, insurance, and association dues, the monthly obligation used in the coverage test.
Cross-collateralization: pledging more than one property to secure a single loan.
Copyable Worksheet
| Line | What goes in |
|---|---|
| Old debts | Each payoff balance and rate |
| Old blended rate | Sum of balance × rate, divided by total payoff |
| Old exit costs | Penalties, exit fees, per-diem interest |
| New loan size | Payoffs + costs + reserves + cash to you |
| New one-time costs | Points, origination, appraisal, title |
| Annual cost, old vs. new | Interest + one-time costs ÷ years held |
| Cost of new cash | Annual cost difference ÷ net cash received |
| Coverage | rent used for lender review ÷ new PITIA |
The usual mistakes: using a simple average, quoting stale payoff figures, ignoring escrows, mixing note rate with all-in cost, and forgetting that the refinance resets the term.
Frequently Asked Questions
Should I use the note rate or the all-in cost?
Start with the note rate to screen offers, then switch to all-in cost to decide. All-in cost adds points, fees, and exit costs spread over your expected hold. A low note rate with heavy fees can lose to a slightly higher note rate with light fees on a short hold.
Does a lower blended cost always mean I save money?
No. Fees, a penalty on the old loan, and a reset term can erase it. A cheaper-looking loan stretched over a longer amortization can also increase total interest. Compare annual cost on the same principal and check break-even against your realistic hold.
Does paying off hard money change the math?
Yes. Hard-money payoffs often carry exit fees and per-diem interest, so the old cost is higher than the rate suggests. That usually makes the consolidation look better, but run it with real payoff figures.
Can a strong property carry a weak one in a pooled loan?
It depends on the program. Some pool rent and payments across properties, while others review each separately. Ask the lender how coverage is measured before you build the plan around it.
Is a no-cost cash-out really free?
Usually the cost moves rather than disappears. Lendmire’s article Who Offers A No Cost Cash Out Refinance? explains where those costs typically land.
