Commercial property replacement costs have risen roughly 40 percent since 2020, according to CoreLogic data. Most commercial properties have not updated their coverage limits to match. That gap sits quietly on the balance sheet until a lender’s underwriting team finds it, and when they do, it can take a deal that looks like a 1.30x DSCR and turn it into a 1.10x in about an hour.
That is not a rounding error. That is a rejection.
Why a $150 Per Square Foot Policy No Longer Passes Lender Review
The trailing 12-month financials a sponsor provides reflect what they actually paid for insurance over the past year. In most cases, that number is based on a coverage limit that has not been updated to reflect what it would actually cost to rebuild the property today.
Lenders know this. During underwriting, most institutional credit teams will not use the sponsor’s historical insurance expense. They will calculate what adequate coverage should cost given current replacement costs and substitute that number into the income calculation. Credit teams have access to construction cost databases that reflect current material and labor costs. The adjustment is not an estimate. It is a calculation based on the same data the underwriter has been trained to use.
If the property is insured at $150 per square foot but local construction costs are running $250 per square foot, the lender is going to underwrite the premium required to cover $250 per square foot. On a mid-size asset, an $80,000 insurance adjustment is not unusual. If the deal was sitting at 1.25x DSCR on sponsor-provided numbers, that single adjustment can push it to 1.12x. Most traditional lenders have a floor somewhere between 1.20x and 1.25x.
The deal that looked like it cleared the screen no longer does — and the lender finds this before you do.
Why Coastal and Storm-Zone Assets Route Differently in 2026
Rising replacement costs affect every market, but the insurance problem runs deeper in coastal states, parts of the Midwest, and anywhere that has seen increased exposure to flooding, hail, or wind events over the past several years. Secondary perils have become the dominant driver of insured losses in commercial real estate. Hail, wind, and storm-driven flooding now account for more claim volume than traditional named storm events. They are also the perils most likely to be underinsured.
Generalist regional banks have quietly pulled back from assets in these areas. Not because the underlying real estate is necessarily bad, but because the insurance picture has become complicated enough that their credit committees are not comfortable underwriting properties where the coverage situation is uncertain or where available policies carry large deductibles for specific perils.
A multifamily asset in a hail corridor or a coastal retail property with a wind deductible the sponsor has never modeled against a loss scenario is not the same underwriting conversation as a stabilized industrial asset in a low-risk market.
Assets with elevated secondary peril exposure need to go to lenders who specialize in that underwriting, not to regional banks whose credit committees are going to flag it as a reason to pass.
Secondary perils are the insurance risk that most deal packages ignore. Lenders do not.
Why the 2026 Insurance Binder Belongs in the Initial Submission
The deals that clear the insurance screen on first review arrive with a current insurance binder, not a historical premium. The sponsor has already gone to market for a 2026 quote that reflects actual replacement costs. That number goes into the income calculation before the package is built, so the DSCR the broker is presenting is the same number the lender is going to calculate on their own.
When you submit a deal with realistic insurance math, you are signaling to the lender that the package has been pre-underwritten. The numbers have been stress-tested before anyone wasted their time on a submission that was going to fail the first adjustment. That reputation accumulates over time and affects how quickly lenders respond to future submissions.
The sponsor also needs to demonstrate the liquidity to fund the insurance reserve at closing. Most lenders require a full 12-month insurance escrow upfront. On a property where the correct premium is significantly higher than what the sponsor has been paying, that escrow requirement can be a substantial cash demand. If the sponsor does not have it, the deal structure needs to account for it before it goes out.
The binder in the initial submission is not a detail. It is the signal that you have done the underwriter’s job before they had to.
The Practical Move
Insurance has traditionally been treated as a closing item. That sequence no longer works. The insurance math affects the income calculation, which affects whether the deal clears the lender’s floor, which determines whether it should be routed to a traditional bank or a different capital source entirely. That decision needs to happen before the first submission goes out.
Before any package is built, pull a current replacement cost estimate for the property. Use the local construction cost benchmark, not the sponsor’s existing coverage limit. Calculate the realistic annual premium at that replacement cost. Substitute that number into the income statement and recalculate the DSCR.
If the adjusted DSCR falls below 1.25x, the deal is not a traditional bank deal in its current form. It might be a private credit deal at rates that match the asset’s complexity, or it might be a deal that needs more equity before it goes to market. Both of those conclusions are better reached at the beginning of the process than three weeks in.
A deal that cannot support adequate insurance coverage at 1.25x DSCR is not a packaging problem. It is a routing problem. Solve it before the first submission.
LoanBase helps you identify which lenders are actively underwriting in markets with elevated insurance complexity and what coverage standards they are applying, so the routing decision is based on current criteria rather than a guess.
