How to Prepare for a Commercial Refinance: Complete Checklist

Preparing for a commercial refinance means getting your property, your financials, and your key underwriting metrics in order before you ever submit an application. In plain English: lenders decide how much to lend you — and at what rate — based on a handful of numbers and documents, and borrowers who walk in with those numbers already polished consistently get faster approvals and better pricing than borrowers who scramble to assemble them mid-process. Preparation matters because commercial refinancing is not like refinancing a home. Underwriters scrutinize the property’s income, your rent roll, your operating expenses, and your personal financial strength, and a single missing document or a weak debt service coverage ratio can stall a deal for weeks or push you into a more expensive loan bucket. This guide walks through exactly what to prepare, how lenders will calculate your numbers, and the steps you can take in the months before applying to strengthen your position.

How to Prepare for Refinance – The Plain-English Definition

Refinance preparation is the process of assembling your documentation and optimizing your property’s financial profile so that a lender can underwrite your loan quickly and at the best available terms. It has three parts:

• The paperwork. Lenders will ask for two to three years of property operating statements, a current rent roll, copies of leases, your existing mortgage statement (including any prepayment penalty language), personal financial statements, tax returns, and entity documents for the LLC or partnership that holds title.
• The numbers. Underwriters reduce your property to a few core metrics — primarily debt service coverage ratio (DSCR), loan-to-value ratio (LTV), and occupancy — and your file needs to clear their minimums.
• The timing. Ideally, preparation starts 6–12 months before your current loan matures or your rate lock on a floating-rate loan becomes painful, so you have time to fix weak spots.

Here is what that looks like on a $1 million property. Suppose you own a small mixed-use building appraised at $1,000,000, with a net operating income (NOI) of $70,000 per year, and you want to refinance the remaining $650,000 balance on your existing loan. Being “prepared” means you can hand a lender: proof of that $70,000 NOI (trailing 12-month operating statement and rent roll), evidence the building is stabilized (occupancy history), your payoff statement showing the $650,000 balance and any exit fees, and clean personal financials. With that package, a lender can quote you in days. Without it, the same request can sit in underwriting purgatory for a month while you chase down lease copies and reconcile expense statements.

The full application-to-closing process is covered step by step in our commercial mortgage refinancing guide — this article focuses on what to do before that process starts.

How to Calculate How to Prepare for Refinance

There is no single “preparation formula,” but there are two calculations every underwriter will run on your file first — and you should run them yourself before any lender does. If you know these two numbers, you know roughly how your application will be received.

1. Debt Service Coverage Ratio (DSCR)

DSCR = Net Operating Income ÷ Annual Debt Service

DSCR measures how comfortably the property’s income covers the proposed loan payments. Most commercial lenders want to see at least 1.20x–1.25x.

2. Loan-to-Value Ratio (LTV)

LTV = Loan Amount ÷ Appraised Property Value

LTV measures how much equity cushion the lender has. Most commercial refinances top out at 65%–80% LTV depending on property type.

Worked example: the $1 million property

Using the building from the previous section:

Input	Value
Appraised value	$1,000,000
Net operating income (NOI)	$70,000/year
Proposed loan amount	$650,000
Example rate / amortization	6.75%, 25-year amortization
Annual debt service	≈ $53,900

• DSCR = $70,000 ÷ $53,900 ≈ 1.30x — comfortably above the typical 1.25x minimum.
• LTV = $650,000 ÷ $1,000,000 = 65% — well inside most lenders’ comfort zone.

This borrower is in good shape and should focus preparation on documentation rather than restructuring the request. If DSCR had come in at 1.10x instead, the preparation work would look very different: raising NOI, reducing the loan amount, or seeking a longer amortization before applying.

You don’t have to build the amortization math yourself — run your own numbers through our DSCR calculator to see exactly where you stand, and use the payment figure it produces to stress-test different rate scenarios.

What Lenders Want to See

Underwriters use your preparation — the documents and metrics above — to sort your file into a risk bucket, and that bucket drives your rate quote. Here is how the review typically unfolds:

1. Sizing. The lender calculates the maximum loan the property supports at their minimum DSCR and maximum LTV, then lends you the lower of the two results. This is why knowing both numbers in advance matters — one of them is almost always the binding constraint.
2. Stabilization check. Lenders want 85%–90%+ occupancy with a seasoned rent roll. A property that just leased up last month reads as riskier than one with two years of stable collections.
3. Sponsor review. Your personal credit (typically 660–680+ for bank programs), liquidity (often 6–12 months of debt service in reserves), and net worth are checked alongside the property.
4. Story items. Deferred maintenance, expiring anchor leases, environmental flags, or litigation all get surfaced — better by you, up front, than by their third-party reports later.

Typical underwriting thresholds vary by property type:

Property type	Typical minimum DSCR	Typical maximum LTV
Multifamily (5+ units)	1.20x – 1.25x	75% – 80%
Industrial / warehouse	1.25x	70% – 75%
Retail (stabilized)	1.25x – 1.30x	65% – 75%
Office	1.25x – 1.35x	65% – 70%
Self-storage	1.25x – 1.30x	70% – 75%
Hospitality	1.40x – 1.50x	60% – 65%

These are market-typical ranges, not promises — every lender sets its own credit box, and the same property can receive meaningfully different terms from a bank, a credit union, a CMBS shop, and a debt fund. That spread is exactly why comparing multiple lenders is worth the effort.

Improving Your How to Prepare for Refinance

If your numbers or your paperwork aren’t where they need to be, the months before your application are when you can actually move them. Here’s what works, roughly in order of impact:

Strengthen the property’s income

• Push occupancy and rents first. Every dollar of added NOI increases both your DSCR and (through valuation) your effective LTV headroom. Renew expiring leases early, fill vacancies even at modest concessions, and document any recent rent increases with signed leases.
• Clean up the expense line. Underwriters work from your operating statements. One-time expenses (a roof replacement, a legal settlement) buried in your P&L will drag down underwritten NOI unless you clearly break them out as non-recurring.
• Bill back what your leases allow. If leases permit CAM, tax, or utility reimbursements you aren’t collecting, start collecting them — recovered expenses flow straight to NOI.

Right-size the request

• Consider borrowing less. Dropping the loan amount is the fastest way to fix a thin DSCR or high LTV. In the $1M example, cutting the request from $750,000 to $650,000 moves LTV from 75% to 65% and lifts DSCR proportionally.
• Ask about longer amortization. A 30-year amortization instead of 20 lowers annual debt service and can rescue a borderline DSCR — at the cost of slower principal paydown.

Fix the sponsor profile

• Pull your credit 6+ months out and resolve errors, pay down revolving balances, and avoid new debt before applying.
• Build documented liquidity. Move reserves into accounts you can show statements for; last-minute transfers raise sourcing questions.

Assemble the file before anyone asks

Have these ready in a single folder: 2–3 years of operating statements, trailing-12-month P&L, current rent roll, lease copies, existing loan payoff statement, property tax bills, insurance declarations, entity docs, personal financial statement, and two years of tax returns. A complete file at submission is the single cheapest “improvement” available — it costs nothing and routinely shaves weeks off closing.

Mind the calendar

Start 6–12 months before loan maturity. That window gives you time to season rent increases, let credit repairs post, and — critically — avoid the desperation discount lenders can sense when a balloon payment is 60 days out and you have no alternatives.

How to Prepare for Refinance Calculator

There isn’t a single calculator that scores “preparedness,” because preparation spans documents, timing, and metrics. But the two calculators below cover the numerical half of the job, and running both takes about five minutes:

• DSCR calculator — enter your NOI, proposed loan amount, rate, and amortization to see your coverage ratio and how it compares to the thresholds in the table above. If you’re below 1.25x, test how much additional NOI or how much smaller a loan gets you over the line.
• commercial mortgage calculator — model your new monthly payment across different rate and amortization scenarios, and compare it against your current payment to estimate the cash-flow impact of the refinance.

Run your numbers in both, note where you’re strong and where you’re thin, and you’ll walk into lender conversations knowing what they’ll see before they see it.

Frequently Asked Questions

What is a good How to Prepare for Refinance?

A “well-prepared” refinance file generally means a DSCR of 1.25x or better, an LTV at or below 75% (lower for office and hospitality), occupancy above 85%–90%, personal credit in the high 600s or better, and a complete document package ready at submission. The exact thresholds depend on the metric and property type — see the lender requirements table above for typical ranges by asset class.

How is How to Prepare for Refinance calculated?

The core preparation math comes down to two formulas: DSCR (net operating income divided by annual debt service) and LTV (loan amount divided by appraised value). The formula section above walks through a worked example on a $1 million property, and the corresponding DSCR and commercial mortgage calculators let you run your own figures in minutes.

How far in advance should I start preparing for a commercial refinance?

Six to twelve months before your current loan matures is the sweet spot. That window gives you time to season rent increases, resolve credit issues, gather documents, and shop multiple lenders. Starting inside 90 days of a balloon maturity limits your options and weakens your negotiating position.

What documents do lenders require for a commercial refinance?

Expect to provide two to three years of property operating statements, a trailing 12-month P&L, a current rent roll, copies of leases, your existing loan’s payoff statement, property tax and insurance records, entity formation documents, a personal financial statement, and two years of personal and business tax returns. Some property types add items — hotels need STR reports, for example.

Can I refinance if my DSCR is below the lender’s minimum?

Sometimes. Options include reducing the loan amount, extending the amortization period, adding a stronger co-sponsor, or working with lenders whose credit boxes accommodate lower coverage (typically at higher rates). The better path, if your timeline allows, is raising NOI before you apply — the improvement section above covers how.
