If you plan to stay in your home more than five years and can lock a competitive fixed rate on a second mortgage, a piggyback loan can beat the cost of PMI over time. If your horizon is shorter, your credit profile is average, or you want a simpler closing, paying PMI is usually the cheaper and easier route. The right choice depends on your monthly payment tolerance, the rate spread between your first and second loans, your closing-cost budget, and how refinancing might affect a second lien down the road.
TL;DR:
- PMI typically costs $30 to $70 monthly per $100,000 borrowed; a $300,000 mortgage therefore carries an estimated $90 to $210 premium.
- Second loan rates often run 1 to 3 percentage points above the first mortgage, and two sets of closing costs can erase monthly savings.
- You can request PMI cancellation at 80% of original home value; servicers must end it at 78% if payments are current, or at loan midpoint.
- Piggyback approval often requires credit in the high 600s, cash reserves, and acceptable debt across both loans; refinancing may require second lien subordination.

Comparing Monthly Costs and Multi-Year Totals
The clearest way to see which option wins for you is to run the numbers side by side. Consider two borrowers each buying a $400,000 home with 10% down, leaving a $360,000 financing need.
If the first mortgage carries a competitive fixed rate and the second loan carries a higher fixed rate typical for piggyback second loans, the combined monthly payments add up to a certain amount reflecting both loans. Total monthly housing payment before taxes and insurance will be the sum of both payments.
Principal and interest run about $2,335 a month. PMI on this loan, per Freddie Mac's rule-of-thumb range, typically runs $30 to $70 per month for every $100,000 borrowed, so on a $360,000 loan that lands between roughly $108 and $252 a month. Using a middle estimate of $180, total monthly payment comes to about $2,515.
In a representative scenario, the piggyback structure may save some amount per month compared to PMI before accounting for closing costs.
- The piggyback route usually means two sets of closing costs, since you are opening two separate loans instead of one.
- PMI costs decline in relative terms as your loan balance amortizes, while a fixed second-loan payment stays flat for its full term.
- A higher second-loan rate, common when rates rise or credit is average, can erase the piggyback's monthly advantage entirely.
A one-point swing in the second-loan rate is often enough to flip which option actually costs less.
Breaking down PMI shows that PMI costs scale with credit score and loan-to-value, which means two borrowers with the same loan amount can see meaningfully different PMI quotes. That variability is exactly why getting an actual rate quote matters more than relying on rule-of-thumb math.

Weighing the Tradeoffs Beyond Monthly Payment
Price is only part of the decision. Each structure carries its own set of practical advantages and friction points that matter over the life of the loan.
Piggyback loan pros:
- Can lower your blended monthly payment when the second-loan rate is competitive and fixed.
- Avoids PMI entirely, which some borrowers prefer on principle even when the math is close.
Piggyback loan cons:
- Requires managing two loans, two statements, and two sets of closing costs.
- The second lien can complicate a future refinance if the second-lien holder will not subordinate.
- Second-loan rates are often variable or priced higher than the first mortgage, adding payment risk.
PMI pros:
- Simpler underwriting and a single closing with one monthly payment.
- Protected by the Homeowners Protection Act, giving you a clear legal path to cancel PMI once you build enough equity.
PMI cons:
- Adds a monthly cost that provides no direct benefit to you as the borrower, only to the lender.
- Cancellation still requires meeting equity thresholds and, in some cases, submitting a request.
Pro Tip: If you go the piggyback route, ask your lender in writing about the second-lien holder's subordination policy before you close, not after you decide to refinance.
Qualifying for a Piggyback Loan vs. a PMI-Backed Mortgage
Lenders evaluate these two paths differently, and that affects both approval odds and pricing.
A piggyback second loan typically asks for a stronger overall profile. Many lenders want a credit score in the high 600s or better, a combined loan-to-value that still leaves meaningful equity, and documented cash reserves to cover both payments if income dips temporarily. Combined debt-to-income across both loans gets scrutinized closely, since you are carrying two obligations instead of one.
PMI pricing, by contrast, is tied more directly to your credit score and loan-to-value ratio on a single loan rather than a separate underwriting decision.
- Piggyback loans are a niche product today compared to their prevalence in the early 2000s, and the CFPB's own consumer guidance notes they require managing two separate loans.
- Not every retail lender offers second-lien piggyback financing, so you may need a broker or specialty lender to access competitive second-loan pricing.
- If your target home price pushes you near the conforming loan limit, a piggyback structure can sometimes help you avoid jumbo pricing on the first mortgage.
Reviewing common down payment mistakes before you apply can also help you avoid structuring errors that affect which option you qualify for.
What PMI and Second-Loan Rates Actually Cost
Getting real numbers before you decide matters more than any rule of thumb. PMI typically ranges from $30 to $70 per month for every $100,000 borrowed, depending on your credit score, down payment size, and loan type. On a $300,000 loan, that works out to roughly $90 to $210 a month, with stronger credit profiles landing at the lower end.
Second-loan rates on a piggyback structure often run one to three percentage points above the first mortgage rate, and many are fixed for a shorter term, such as 10 or 15 years, which raises the monthly payment relative to a 30-year first mortgage. Some piggyback second loans are structured as home equity lines of credit, which carry variable rates that can rise after closing.
- Expect two sets of closing costs with a piggyback structure, since you are financing two separate loans.
- PMI closing costs are built into the single-loan closing process and typically add less upfront complexity.
- A simple breakeven check: compare the monthly dollar difference between the two structures against the extra closing costs the piggyback requires, and divide to find how many months it takes to recoup that difference.
On a $300,000 first mortgage, PMI can run anywhere from $90 to $210 a month depending on your credit score and down payment, which means the "right" answer genuinely depends on the quote you receive, not a generic average.

How PMI Cancellation Works and Why a Second Loan Does Not Expire
PMI has a built-in sunset that a piggyback second loan simply does not. Under the Homeowners Protection Act, you can request PMI cancellation once your loan balance reaches 80% of the home's original value, and your servicer must automatically terminate PMI once your scheduled balance reaches 78% of the original value, provided you are current on payments. If neither happens earlier, PMI must terminate at the loan's midpoint.
A CFPB compliance bulletin notes that servicers sometimes apply investor guidelines incorrectly and wrongly deny cancellation requests, so it is worth tracking your amortization schedule yourself and requesting cancellation in writing once you hit the 80% threshold.
A piggyback second loan carries no equivalent legal sunset. It simply amortizes on its own schedule until you pay it off or refinance it away.
- Request PMI cancellation in writing once your balance reaches 80% of the original value, and keep a copy of the request.
- Track your amortization schedule so you know your automatic termination date even if you never request early cancellation.
- Understand that refinancing out of a piggyback structure requires either paying off the second loan or getting the second-lien holder to agree to subordinate to the new first mortgage, a process Fannie Mae's subordinate-financing guidance governs in detail.

A Six-Question Checklist to Decide Between the Two
Answering these questions honestly will point you toward the right structure faster than comparing rate sheets alone.
- How many years do you realistically expect to stay in this home before selling or refinancing?
- Are you comfortable managing two separate loan payments, statements, and due dates?
- Do you expect to refinance within the next few years, and have you asked a potential second-lien lender about its subordination policy?
- How sensitive is your monthly budget to a rate that might be one to three points higher on the second loan?
- Can you cover two sets of closing costs now, or does a single-loan closing better fit your cash position?
- Does your target lender even offer piggyback second-lien financing, or would you need a specialty source?
Once you have answers, request three things from any lender you are considering: a sample amortization schedule for the first mortgage, a PMI rate quote based on your actual credit score and down payment, and, if you are exploring a piggyback, a second-loan term sheet with the exact rate and term. Compare total cost, not just monthly payment, across three horizons.
Pro Tip: Run your total cost comparison at the 1-year, 3-year, and 7-year marks, since the structure that wins at year one often is not the one that wins at year seven.

Why the Math Alone Rarely Settles This Decision
Our team works with buyers who are weighing exactly this tradeoff, and the pattern we see most often is that the "cheaper" option on paper is not always the one that fits a borrower's actual plans. Before we recommend a direction, we ask for a first-loan rate quote, a second-loan quote if a piggyback is on the table, a PMI premium estimate based on the borrower's real credit profile, closing-cost estimates for both structures, and, when a second lien is involved, information about the lender's subordination policy.
We then build a side-by-side worksheet showing monthly payment, closing costs, and multi-year totals for each path, so the comparison is grounded in the borrower's actual numbers rather than a generic rule of thumb, and we recommend the route that fits the borrower's timeline and risk tolerance.
What Most Advice on This Topic Gets Wrong
Most articles comparing piggyback loans to PMI treat the decision as a pure math problem, and that misses the point. The math changes every time a rate sheet updates, but two things do not change: PMI has a legal cancellation path under the Homeowners Protection Act, and a second lien does not. That asymmetry deserves more weight than most comparisons give it.
The conventional advice tends to treat "avoid PMI" as a goal in itself, when in reality PMI is often the simpler, more flexible choice for anyone who is not certain they will hold the home long enough to recoup a second loan's closing costs and rate premium. Where a piggyback can genuinely win is a specific profile: a borrower with strong credit, access to a competitively priced fixed second loan, and real conviction about staying put for years.
If you take one thing from this comparison, prioritize getting real quotes before comparing structures in the abstract. A rule-of-thumb breakeven is a starting point, not a decision.

FAQ
Are piggyback loans a good idea?
A piggyback loan can make sense if you have strong credit, can secure a competitively priced fixed second loan, and plan to stay in the home long enough to recoup the extra closing costs. For shorter time horizons or average credit, paying PMI is usually the simpler and often cheaper choice.
Are piggyback loans still available?
Yes, though they are far less common than they were in the early 2000s, and the CFPB notes that borrowers typically need a lender or broker who specifically offers second-lien financing. Availability and pricing vary significantly by lender, so it often takes more shopping than finding a standard PMI quote.
Is it hard to get a piggyback loan?
Qualifying typically requires stronger credit, documented cash reserves, and a combined debt-to-income ratio across both loans that lenders are comfortable with. Because fewer lenders offer this structure, working with a broker who has access to second-lien financing can make the process considerably smoother.
How much is PMI on a $300,000 loan?
PMI on a $300,000 loan typically runs between $90 and $210 a month, based on the rule-of-thumb range of $30 to $70 per $100,000 borrowed. Your exact premium depends on your credit score, down payment size, and loan type, so a personalized quote is the only way to know your real number.
