Refinance a Balloon Commercial Mortgage 6 Months Early — The Pre-Maturity Playbook

Commercial mortgages structured as balloon loans (5- or 10-year fixed periods followed by full balance due) create a refinancing pressure point that catches many borrowers off guard. The borrowers who start the refi 6 months ahead end up with competitive permanent financing at near-market rates. The borrowers who wait until 60 days out end up paying bridge rates or accepting subpar terms under deadline pressure. This page walks the 6-month playbook, prepayment penalty mechanics, and the refi options. For broader CRE context see commercial real estate loans; for rates see CRE loan rates 2026.

Why 6 Months Is the Right Lead Time

• Permanent CRE underwriting takes 60–90 days minimum. Agency multifamily 60–75 days; bank conventional 45–75 days at relationship bank, 60–90 at new bank; CMBS 60–75 days; life co 60–90 days; FHA 6–9 months. None of these can compress.
• Third-party reports take their own time. Commercial appraisal 2–3 weeks; environmental Phase I 7–14 days; title commitment 7–14 days; property condition assessment 2–3 weeks. Often run in parallel but can hit delays.
• Lender shopping takes time. Applying to 2–3 permanent lenders in parallel for competitive offers requires 30–45 days from initial outreach to term sheets received.
• Diligence surprises eat schedule. Environmental Phase II requirement (4–8 weeks), title objections (2–4 weeks to clear), appraisal coming in short (1–2 weeks to restructure or contest), tenant estoppel issues — each potential delay needs schedule buffer.
• Prepayment penalty windows shift. Many loans have decreasing prepayment penalties or open windows in last 90–180 days. 6-month lead lets you time the close to minimize penalty.
• Negotiation leverage requires not being in distress. Lenders sense urgency and price accordingly. A borrower with 6 months runway has 5x more leverage than a borrower with 60 days.

Prepayment Penalty Mechanics

The amount you pay to prepay before maturity depends on loan type:

CMBS / agency defeasance

• Most CMBS and many agency loans use defeasance — borrower buys a portfolio of U.S. Treasuries that mirrors the loan's remaining cash flows. Lender continues receiving payments from the Treasury portfolio; borrower owns the bond portfolio and recovers some value at the loan's original maturity.
• Cost varies with Treasury rates. When Treasury yields are below the loan's coupon, defeasance is expensive (5–15% of balance). When Treasury yields are above the coupon, defeasance can be near-free or even net positive.
• Defeasance window: Typically closed for first 1–3 years of loan, then open until last 1–6 months (when borrower can prepay without defeasance).
• Process: 30–60 days to structure defeasance transaction; defeasance consultant required ($15K–$50K fees).

Bank yield maintenance

• Bank loans commonly use yield maintenance — borrower pays a penalty equal to the present value of remaining interest payments above current Treasury yield (the “make-whole”).
• Cost: Typically 2–5% of balance with longer remaining term and lower current rates increasing the cost.
• Open window: Last 90–180 days of loan typically have reduced or no yield maintenance.

Step-down prepayment penalty

• Some bank and agency loans use step-down structures: 5% in year 1, 4% in year 2, 3% in year 3, etc., decreasing to 0% in last year.
• Predictable; easier to plan around than defeasance or yield maintenance.

Open prepayment (no penalty)

• Some smaller bank loans and most short-term bridge loans have open prepayment with no penalty after an initial lock period.
• Check your loan documents — assumption that you can prepay freely is sometimes wrong.

Why Borrowers Wait Too Long (And Pay For It)

Common reasons borrowers don't start 6 months out:

• Assumed lender would extend. Most CRE balloon loans don't auto-extend. Lender owes you no extension; some won't extend at all, others extend only at premium (rate bump, extension fees).
• Hoped rates would drop. Waiting for better rates is common; rate timing rarely beats the cost of last-minute refi. Refi now at known rate beats hoping for unknown rate while running out of runway.
• Property had issues being addressed. Sometimes legitimate — lease-up, value-add not complete, NOI not where it needs to be. But often the issues take longer than expected, eating the runway.
• Underestimated the timeline. Borrowers familiar with residential mortgage (30–45 days) underestimate commercial permanent timeline (60–90 days).
• Didn't track maturity date. Surprisingly common. Maturity date should be in your operations calendar with 6-, 9-, and 12-month warnings.

The 6-Month Playbook (Month-by-Month)

Month -6 (6 months before maturity)

• Confirm exact maturity date and read loan documents for prepayment penalty terms
• Calculate current NOI, T-12 cash flow, stabilization status
• Engage mortgage banker (recommended for $5M+ deals) or directly contact 2–3 permanent lender categories
• Get indicative term sheets from agency, bank, life co, CMBS, SBA 504 (whichever fits)
• Determine target permanent loan amount + LTV + DSCR

Month -5

• Pick lender category and submit formal application to 1–2 primary candidates
• Submit complete package: sponsor PFS + tax returns, subject property T-12 + T-3 + rent roll + leases + property condition
• Order third-party reports: appraisal, environmental Phase I, title commitment, survey if needed
• Engage closing attorney

Months -4 to -3

• Lender underwrites; third-party reports come in
• Conditional commitment letter received
• Conditions identified: insurance binding, additional reports, lease estoppels, entity good standing, etc.
• Start clearing conditions

Month -2

• Conditions cleared
• Loan documents drafted by lender attorney
• Borrower attorney reviews; negotiates final language
• Settlement statement prepared
• Calculate prepayment penalty payoff on existing loan + verify open-window timing

Month -1 to maturity

• Final close coordination
• Close on permanent refi; lender wires payoff (including any prepayment penalty) to existing lender
• Existing lender confirms payoff, releases mortgage 14–30 days post-close
• New permanent loan service begins

Timing the Prepayment Penalty Window

Most loans have predictable prepayment penalty curves. Time the refi close to minimize:

• Last 90 days of most loans: Reduced or no prepayment penalty. Close refi during this window if possible.
• Last 30 days: Often zero prepayment penalty. Ideal timing if your refi process can land here.
• Last 6 months but still in penalty period: Calculate penalty cost vs refi rate savings. Sometimes paying a 1–3% penalty is worth it to lock in current rates before they move; sometimes worth waiting 60–90 days for penalty to drop.
• Defeasance interest rate sensitivity: Defeasance cost varies with Treasury yields vs loan coupon. If Treasury yields are rising, defeasance gets cheaper — waiting may save money. If falling, defeasance gets more expensive — refi sooner.

Refi Path by Asset Type

• Stabilized 5+ unit multifamily: Agency (Freddie SBL, Fannie Small Loan, FHA 223(f)). 5.5–7% fixed. Non-recourse. See hard money to permanent.
• Stabilized retail, office, industrial $5M+: Life insurance company. 5.5–7% fixed. Lowest rates. Mortgage banker required.
• Stabilized CRE $2M–$50M, non-recourse desired: CMBS. 6–8% fixed, 10-year balloon, 30-year amortization.
• Mid-size CRE $1M–$15M, relationship or recourse OK: Bank conventional. 7–8% fixed. Faster + more flexible than agency.
• Owner-occupied CRE: SBA 504 if borrower business operates from property. ~6.5–7.5% blended. Often cheapest for owner-occupied.
• Value-add or non-stabilized: Institutional bridge refi to stabilize, then refi to permanent. See bridge loan rates.

If You're Late: Last 90 Days Scrambles

If maturity is <90 days and you haven't started refi:

• Apply to permanent lenders immediately, even though timeline is tight. Some agency and bank lenders can close in 60 days for clean deals.
• Request maturity extension from current lender. Most CRE lenders grant 30–90 day extensions for a fee (0.5–1% extension fee + rate bump). Costs $5K–$30K but buys time to close clean permanent refi.
• Refi to institutional bridge as intermediate step. Bridge at 9–11% (vs current ~7%) closes in 30–45 days. Use for 12–18 months while you arrange permanent. Expensive but available.
• Refi to hard money / private money as last resort. Closes in 7–21 days at 10–14% interest + 2–5 points. Significantly expensive but works for true emergencies. See bridge loan close in 7 days.
• Negotiate with current lender for modification or extension. Lender prefers continued performing loan over default. Often willing to modify for 6–12 months at modest premium.

What to Watch Out For

• Defeasance cost surprise. Defeasance is calculated daily based on Treasury yields. Get a fresh defeasance quote within 7 days of intended close — can vary $50K–$200K from month to month on $5M+ loans.
• Lockbox / cash management transition. Many CMBS loans require lockbox or cash management agreements during life of loan. Transitioning these to new lender adds 1–2 weeks of operational complexity.
• Yield maintenance using wrong index. Some loans calculate yield maintenance against specific Treasury maturity; confirm exact formula in loan docs.
• Loan modification vs refi. Sometimes lender will modify existing loan (rate reduction, term extension) instead of refi. Modification costs are typically lower than full refi but may not capture full available rate reduction.
• Lender consent for prepayment. Some loans require lender consent for prepayment even within open window. Reach out to current lender 60–90 days ahead of intended payoff.
• NOI variance vs original underwriting. If current NOI is meaningfully lower than original underwriting NOI (e.g., due to a recent tenant loss), new permanent loan amount sizes to current NOI, potentially short-funding the payoff.

Get Matched for Balloon Refi

If your CRE balloon matures in 3–12 months, start the refi process now. Get matched for CRE refi — one application submits to agency, bank, life co, CMBS, and SBA 504 permanent lenders. Also see CRE permanent rates 2026, CRE closing timeline, CRE refi delays, and CMBS vs life co vs agency.
