The Quick Read: A refinance is worth the closing costs only when your total upfront cost, divided by the real monthly savings, gives a break-even point shorter than the time you will keep the property and the loan. On very large balances the costs are big in absolute terms, and bank statement pricing often leaves the savings thin. Run the test on quoted numbers, not on rules of thumb.
- Break-even months equal total refinance costs divided by monthly savings. If you will not hold the loan that long, skip it.
- Qualifying income comes from 12 or 24 months of eligible deposits after an expense ratio, so the deposit review can move your savings before you apply.
- Leverage steps down as the loan grows, and every file above $4,000,000 is reviewed case by case.
- A refinance to pull cash out has a different test than a refinance to improve the payment.
- For rentals, a property-income path can sometimes replace personal-income documents entirely.
When Does a Super Jumbo Refinance Pay for Itself?
It pays for itself when you keep the loan past the break-even point and the savings are real, meaning measured from the actual old and new payment structures. The formula is simple. Total costs divided by monthly savings equals the months you need to hold.
Three situations usually justify a refinance on a large balance:
1. The existing structure is about to change. An interest-only period ends, or an adjustable loan nears its reset.
2. You need cash-out for a purpose with a return. Buying another property or funding a business can outweigh the cost of the funds.
3. Your income documentation changed. You may now qualify on bank statements in a way you could not before, or the reverse.
Two things make the math harder than on a smaller loan. Costs that scale with balance, such as title and escrow, grow with the size of the loan. And non-QM pricing, meaning pricing for loans that do not fit standard agency boxes, often sits above agency pricing, so the monthly savings can be small. A modest payment improvement against a large cost stack is the classic losing trade.
Key Terms Defined
Super jumbo: A loan large enough that it sits above ordinary jumbo programs. Through the wholesale network Lendmire places files with, the line where tighter overlays begin is $3,500,000 on a primary residence and $3,000,000 on a second home or investment property.
Bank statement loan: A mortgage that is reviewed around documented deposits in your personal or business accounts rather than on traditional personal-income documentation. It is reviewed on documented income under the applicable program, subject to lender guidelines.
Eligible deposits: Deposits that count as income after the lender strips out transfers between your own accounts, loan proceeds and other non-income credits.
Break-even: The number of months until the monthly savings add up to what the refinance cost you.
Cash-in-hand: The cash you actually receive on a cash-out refinance after paying off the old loan and costs. It is often much smaller than paper equity.
How Bank Statement Income Gets Counted
Underwriters add up eligible deposits across the statement window, apply an expense ratio if the account is a business account, and divide by the number of months. That result feeds your debt-to-income ratio. Scotsman Guide’s non-QM overview describes the same design: 12 to 24 months of statements, with a profit-and-loss statement or a third-party tax professional’s expense statement able to stand in for a flat expense factor.
Across the wholesale network, the mechanics look like this:
- Statement window: 12 or 24 consecutive months of personal or business statements. The bank portfolio program uses 12. Transaction histories never substitute for statements.
- Business accounts: You need at least 25% ownership. Fixed expense ratios run 20% for a service business with no employees, 40% for one to five employees, and 50% for six or more employees or any product business. An accountant-provided ratio is an option, and so is a profit-and-loss method capped at 80%.
- Personal accounts: Transfers from your own business into your personal account count in full.
- Limits: Debt-to-income can reach 50%. The credit floor is 660 on the portfolio program, 680 on the bank portfolio program, and 700 above the super jumbo line on the portfolio program.
Why does this matter for the refinance decision? Because the income that qualified you on the original loan may not repeat. A year with large unexplained transfers or lumpy deposits can shrink qualifying income. A smaller income number can push you into a lower leverage cell, and that can erase the savings you planned around. Check your deposits first, before you spend money on an appraisal.
What Sits Inside the Closing-Cost Stack
The stack has several layers, and they behave differently on a big loan. Sorting them tells you where you have leverage to negotiate.
| Cost layer | Who is paid | Usually negotiable? |
|---|---|---|
| Origination or broker compensation | Lender or broker | Often |
| Optional pricing buy-down | Lender | Your choice |
| Appraisal (sometimes more than one) | Third party | Rarely |
| Title and escrow | Third party | Sometimes shopped |
| Recording and prepaids | Government, escrow | No, and prepaids are timing items |
Two details are easy to miss. Prepaid items such as interest and escrow deposits are money you would have spent anyway, so do not count them against the refinance. And if your existing loan carries a prepayment penalty, that penalty is a real cost of leaving it and belongs in the break-even.
Tax treatment can depend on how the funds are used and how the property is held; borrowers should keep clear records and speak with a qualified tax professional before relying on any deduction.
How Loan Size Limits What You Can Borrow
Leverage falls as the loan grows, so the cash you can take out is often far less than your equity suggests. These figures are ceilings through select wholesale programs, subject to full underwriting, and the band is the loan amount, not the property value.
On a primary residence, rate-and-term refinance ceilings run 90% to $1,000,000, 85% to $2,000,000 and 80% to $3,000,000. They are 75% from $3,000,000 to $3,500,000 and 70% from $3,500,000 to $4,000,000. Cash-out on a primary residence runs 80% to $1,500,000, 75% to $2,000,000, 70% to $3,000,000 and 65% to $4,000,000.
Above $4,000,000 a bank portfolio program takes over. It carries files to $30,000,000, and every figure there is reviewed case by case before submission. On a primary residence in the $4,000,000 to $5,000,000 band, a rate-and-term ceiling of 65% and a cash-out ceiling of 60% are the starting point on review.
Investment property takes its own ladder. On an investment property, rate-and-term ceilings run 85% to $1,000,000 and 80% from there to $2,500,000. Beyond that, ceilings drop to 75% for loans to $3,000,000, then 60% for loans from $3,000,000 to $4,000,000 on the bank portfolio program.
Cash-out has extra rules. Proceeds are unlimited at or below 60% LTV. Above 60%, the portfolio program caps cash-in-hand at $1,500,000. On files above the super jumbo line, cash-out proceeds cannot be used to satisfy reserves. Reserves run 3 months to $500,000, 6 months to $1,500,000 and 9 months above that. If you are weighing how liquid those reserves must be, Lendmire’s piece on whether super jumbo bank statement reserves have to be liquid at closing covers it. Exact terms depend on the lender’s guidelines, property type, leverage, and a full review of the borrower’s file.
Three Break-Even Cases: Strong, Marginal and Failing
The cases below are qualitative on purpose. Plug in your own quoted numbers.
| Case | Savings vs. cost stack | Hold period | Verdict |
|---|---|---|---|
| Strong | Large monthly drop; costs modest against it | Long | Likely worth it |
| Marginal | Small monthly drop; large cost stack | Longer than the break-even, barely | Run a stress test |
| Failing | Tiny drop or a higher payment | Short, or a sale is planned | Skip it |
Picture an owner of a $3,200,000 primary residence whose adjustable loan is about to reset. If the new structure cuts the monthly obligation meaningfully and the owner plans to stay for years, the strong case fits. Now picture an investor who might sell within a few years and would save only a little each month. That is the failing case, because the savings never catch up with the costs.
Stress-test the marginal case three ways. First, cut your qualifying income to see whether it still fits the leverage band you planned on. Second, assume the appraisal lands below your estimate. Third, shorten the hold period by a year or two. If the deal still works under all three, it is solid. If one breaks it, treat the refinance as a coin flip.
Pay Now, Roll It In, or Take Higher Pricing?
You have three ways to handle costs, and none of them is free. Paying in cash keeps the new balance clean but raises your upfront outlay. Rolling costs into the loan raises the balance and lengthens break-even. A lender-credit or no-closing-cost offer moves the cost into the pricing, so you pay it over time.
The CFPB’s assessment of the ability-to-repay rule notes that lenders sometimes waive fees and offset them with higher pricing. Ask for both versions of the quote and compare total cost over your expected hold period.
When Not to Refinance
Skip it when the hold period is short, the savings are small, or your qualifying income would come in lower than before. Also skip it when a prepayment penalty on the old loan eats most of the benefit.
Some alternatives avoid the closing costs altogether. You can keep the loan and wait. You can ask your current servicer about a recast or modification, if your loan allows it. And if your balance is on rental property, you can look at a property-income path.
That last option deserves a second look. A DSCR loan is reviewed primarily on property-level rental income covering the payment, subject to lender guidelines, and it applies to investment property only. It carries its own cost structure and leverage rules, so compare it against the personal-income path rather than assuming one is cheaper. Lendmire’s complete DSCR loans guide explains how that route works.
Does Business Purpose Change the Rules?
It can, and the loan’s purpose decides, not the collateral. Rental-property loans are business-purpose investor loans, and they are reviewed differently from a standard owner-occupied mortgage. The CFPB’s Regulation Z commentary on exempt credit exempts credit extended primarily for a business purpose. It also says the lender must decide that in each case. A loan with consumer-purpose proceeds, such as paying for personal expenses, stays consumer credit even when a rental secures it.
For a primary or second home, ability-to-repay standards apply to the loan. For a true business-purpose rental refinance they generally do not. Your lender classifies the loan, and you should know which side yours falls on.
Before You Pay for an Appraisal
Work through this list first:
1. Pull the old loan’s payoff terms, including any prepayment penalty. 2. Get written quotes in two forms, one with costs paid and one with costs absorbed into pricing. 3. Total your eligible deposits for 12 and 24 months and see which window helps. 4. Check your loan amount against the leverage band for your occupancy, and note that above $4,000,000 everything is case by case. 5. Decide your realistic hold period, then divide costs by monthly savings.

Frequently Asked Questions
Do super jumbo refinances cost more than smaller ones?
In absolute terms, yes, because items like title and escrow scale with the balance, and large loans can need more than one appraisal. As a share of the loan the difference depends on the quote. Always compare the dollar total, not just the percentage.
Can I refinance on bank statements if my traditional personal-income documentation shows low income?
Often, yes. A file is reviewed on documented income under the applicable program, subject to lender guidelines. Credit, assets and reserves are still verified, so the process is thorough, not loose.
Does a cash-out refinance change the break-even test?
It does, because you are paying for access to cash, not only for a lower payment. Compare the cost of the funds against what you will earn or save by using them. Cash-in-hand is also capped at $1,500,000 above 60% LTV on the portfolio program, so equity alone does not set the proceeds. Every figure here varies by lender and program — guidelines, property type, leverage, and credit profile all apply.
Is 50% always the expense ratio on business statements?
No. It applies to a business with six or more employees or any product business. A service business with no employees can use 20%, one to five employees 40%, and an accountant-provided ratio is also an option.
Is a DSCR refinance a cheaper alternative for a rental?
Not automatically. It skips personal-income documents, but it has its own leverage ladder and cost structure. Run both quotes and compare total cost over your hold period.
