Refinance Timing Optimizer

The four variables that determine refi timing

Refinance timing is a four-variable optimization problem. Get any one of these wrong and your break-even math falls apart:

1. Your current PPP schedule

Every month you wait burns another month off the PPP window. If you're at month 18 of a 5/4/3/2/1 (year 2 = 4%), waiting 6 more months drops you into year 3 (3%) and saves roughly 1% of your outstanding balance — on a $400k balance, that's $4,000 of pure savings just for waiting.

See our dedicated prepayment penalty analyzer for exact PPP cost at every exit year on your specific loan.

2. The rate direction

If the market is pricing rate cuts, waiting 6-12 months can capture 50-100 bps of rate improvement — which on a $400k loan is $100-200/month in P&I savings, or $60,000-120,000 over a 30-year term. If the market is pricing hikes or flat, every month you wait risks paying more later.

How to form a view: watch the 2-year Treasury and the MBS OAS spread. DSCR rates typically track 10-year Treasury + 350-425 bps. If the forward curve prices Fed cuts, DSCR rates will likely follow within 3-6 months.

3. Seasoning requirements

You can't refi until the lender is willing to underwrite. Rate-and-term DSCR refis typically require 6 months of title seasoning. Cash-out refis typically require 6-12 months. A handful of aggressive non-QM programs will refi at 3 months seasoning at a rate premium (25-50 bps). Plan around 6 months minimum for refi eligibility.

4. Appreciation

If you're in a cash-out scenario, waiting for appreciation is often worth more than waiting for a rate cut. A 5% annual appreciation on a $500k property generates $25,000 of new equity per year — and at 75% LTV, that's $18,750 of additional cash-out capacity. Against a 50 bps rate drop saving $140/month on $400k, appreciation often wins.

Break-even math, walked through

The break-even month is when your cumulative monthly savings exceed the upfront refi cost. The formula:

Break-even months = (PPP cost + closing costs) / monthly P&I savings

Worked example

• Current: $380,000 balance at 8.25%, P&I $2,856/month
• New at 7.25%: $2,592/month P&I — saves $264/month
• PPP (year 3, 3%): $11,400
• Closing (2.5% of new loan): $9,500
• Total cost: $20,900
• Break-even: $20,900 / $264 = 79 months (6.6 years)

If you'll hold past 6.6 years, refi makes sense. If you expect to sell or refi again within 6 years, think twice — you won't recover the transaction cost.

When to wait vs act

Act now when...

• Rates have dropped 50+ bps from your origination rate
• You're past the PPP window (year 6+ on a 5/4/3/2/1) or in a state that bans PPP
• The property has appreciated 15%+ and you want to pull cash out
• You're holding to 10+ years and break-even falls inside that window
• Your current DSCR has improved (rent bumps) and you can hit a better pricing tier

Wait when...

• The Fed's forward curve prices 50+ bps of additional cuts
• You're in year 1 or 2 of a 5/4/3/2/1 — PPP alone eats the savings
• Your hold horizon is <5 years — break-even doesn't land
• Your property is still appreciating fast (10%+/yr)
• You'd pay a cash-out premium (25-50 bps) but don't actually need the cash — a future rate-and-term might be cheaper

Rate-lock considerations

DSCR lenders typically offer 30-day and 45-day locks at no cost. Extended locks cost 25-50 bps and run 60-90 days. Float-down options cost 25-50 bps and let you re-lock lower if rates drop after your initial lock. On a rapid-move rate environment, the float-down often pays for itself.

If you're locking with cash-out contingent on an appraisal, lock only after the appraisal is ordered and likely on its way back. An under-appraisal kills your cash-out and the lock fees become sunk cost.

Rate-and-term vs cash-out refinance

A rate-and-term refinance replaces your existing loan with a new loan at the same or a lower balance — pure rate-capture, no cash out. DSCR rate-and-term pricing is typically the cleanest and tightest in the market.

A cash-out refinance takes on a new loan above your existing balance and puts the difference in your pocket. Cash-out pricing runs 25-50 bps higher and LTV caps are tighter (usually 75% vs 80%). Use cash-out when you need capital for new acquisitions or capital improvements — not for "cheap" spending money.

Factoring appreciation into the decision

On appreciating properties, the refi-timing decision is really a three-way optimization: rate direction, PPP burn-down, and equity growth. If your property appreciates 5%/year and you're not planning to tap equity now, you can usually wait — another 12 months buys you better rates, a cheaper PPP, and $20-40k of additional refi capacity on a $500k asset.

Conversely, if the market is softening and you might see price declines, acting now can lock in current valuations. This is especially important for cash-out refis — you're financing based on today's appraisal, and if values drop 10% in six months your cash-out capacity drops with them.

DSCR re-qualification at the new loan

Don't forget that the new loan has to underwrite on DSCR too. If your rents have increased since origination, you'll qualify at a better pricing tier (DSCR 1.20+ is the typical sweet spot). If rents have lagged, you may fall into a lower tier and pay a rate premium that erodes your savings. Before you commit to a refi, confirm your current market rent with a 1007 market rent form — the appraiser-provided rent is what the lender will use.

Special situations

Refinancing a partial-year-old BRRRR

If you just BRRRR'd a property and want to refi out of your initial DSCR loan into a better rate, you'll face a PPP trigger because you're inside year 1 of 5/4/3/2/1. Usually this means waiting 12-18 months unless the rate drop is dramatic. Alternative: ask your original lender for a same-lender refi waiver, which some offer on the PPP.

Refinancing before selling

Don't do this. If you're selling within 6 months, just sell — the buyer assumes or takes new financing, and you avoid the PPP by not triggering prepayment. Refinancing just to have a lower rate for 6 months is almost always a losing trade.

Restructuring into a portfolio loan

Moving multiple standalone DSCR loans into a single blanket triggers PPP on each original loan. The analyzer above handles single-loan refis — for multi-property blanket restructures, use the portfolio DSCR analyzer to model the full transaction including aggregate PPP costs.

Using this tool

Enter your current loan details, your PPP schedule, your best guess at rates over the next 3-24 months, and your property's current value and expected appreciation. The tool will show you the projected math at each horizon and highlight the horizon with the best 5-year net ROI.

Pro tip: run three versions of this model. One with your base case rate outlook, one with a bull case (rates drop 100 bps more than expected), and one with a bear case (rates flat or rising). If the optimal horizon is the same in all three, you have a robust plan. If the horizon swings wildly, the honest answer is "wait and watch" — the expected value of waiting is high because the downside (one more year of status quo) is small and the upside (locking a materially better rate) is large.
