Prepayment Penalties: The Math Nobody Shows You (And Why the Lowest Rate Isn't Always the Cheapest)

Many real estate investors focus on the interest rate—but overlook one of the most expensive parts of their loan: the prepayment penalty.

A lower interest rate can save you money each month, but if you refinance or sell the property sooner than expected, that "great deal" could end up costing thousands.

What Is a Prepayment Penalty?

A prepayment penalty is a fee charged by some lenders if you pay off your mortgage before a specified period ends.

This commonly happens when you:

• Refinance the property
• Sell the property
• Pay off the mortgage early
• Replace the financing with another lender

These penalties are most common on investment property loans, including DSCR and other Non-QM products.

Good to Know: Conventional, FHA, and VA loans for owner-occupied homes generally do not have prepayment penalties.

Why Do Lenders Charge Them?

Think of your mortgage as an investment for the lender.

When they originate your loan, they expect to earn interest over several years. If you refinance after only 12 or 18 months, they lose a significant portion of that expected return.

A prepayment penalty helps offset that risk.

The Biggest Misconception

Many investors assume:

"I'm planning to keep the property for years, so it doesn't matter."

Unfortunately...

Plans change.

You may decide to:

• Refinance because rates dropped
• Pull cash out for another investment
• Sell after renovations
• Complete a BRRRR strategy
• Exchange into another property

What seemed like a long-term investment can quickly become a short-term loan.

Types of Prepayment Penalties

1. Percentage-Based Penalty

This is the easiest structure to understand.

Loan BalancePenaltyAmount Owed

3%

$12,000

Simple.

Pay off the loan during the penalty period...

You owe 3% of the balance.

2. Declining 3-2-1 Penalty

Very common with DSCR loans.

Example on a $500,000 loan:

Year 2

$10,000

Year 3

$5,000

After Year 3...

No penalty.

3. Declining 5-4-3-2-1 Penalty

Often found on larger investment loans.

These loans often offer better pricing, but you're giving up flexibility.

The Math Nobody Shows You

Let's compare two real loan offers.

Loan Option A

✅ Interest Rate: 6.25%

❌ 3-Year Prepayment Penalty

Loan Option B

Interest Rate: 6.50%

✅ No Prepayment Penalty

Most borrowers immediately choose Option A because the payment is lower.

But here's the catch...

Imagine rates fall 18 months later.

You refinance your $500,000 loan.

Your penalty could still be approximately:

$10,000

Now ask yourself...

How much did the lower payment actually save you over those 18 months?

If the monthly savings totaled $4,500, but the penalty costs $10,000, the "cheaper" loan actually cost you $5,500 more.

The lowest interest rate isn't always the lowest-cost loan.

Think Like an Investor

Instead of asking:

"Which loan has the lowest rate?"

Ask:

• How long do I expect to own this property?
• Would I refinance if rates drop?
• Am I planning renovations?
• Could I sell sooner than expected?
• Will I need cash out in the next few years?

These answers often matter more than the interest rate itself.

When a Prepayment Penalty Can Actually Be a Good Thing

Surprised?

Sometimes accepting a prepayment penalty allows you to receive:

✔ Lower interest rate

✔ Higher cash flow

✔ Better DSCR qualification

✔ More loan proceeds

✔ Improved lender pricing

If you're buying a property you intend to keep for 10+ years, accepting a penalty may actually make financial sense.

Questions You Should Always Ask Your Lender

Before locking your loan, ask:

• How is the penalty calculated?
• Does it decline every year?
• Is it based on the original balance or current balance?
• What happens if I refinance?
• What happens if I sell?
• Can I make extra principal payments?
• Are there loan options without a penalty?
• How much lower is the interest rate because of the penalty?

These questions can save you thousands.

Real Investor Example

Imagine two investors purchasing identical rental properties.

Investor A

• 6.25% interest rate
• 3-year prepayment penalty

Eighteen months later...

Rates fall dramatically.

They refinance.

Penalty Paid: $10,000

Investor B

• 6.50% interest rate
• No prepayment penalty

Rates fall.

They refinance immediately.

Penalty Paid: $0

Investor B paid a slightly higher monthly payment—but had complete flexibility when the market changed.

Sometimes flexibility is worth far more than a lower payment.

Bottom Line

Prepayment penalties aren't inherently good or bad.

They're simply another cost that should be evaluated alongside:

• Interest rate
• Closing costs
• Monthly payment
• Cash flow
• Long-term investment strategy
• Expected holding period

The best loan isn't necessarily the one with the lowest rate.

It's the one that aligns with your investment goals.
