How Should You Insure a Portfolio of Texas Commercial Properties?

What Does a Portfolio Insurance Program Usually Include?

Most Texas owners with several commercial properties need the same building blocks as a single-property owner, organized across every location. The core pieces are property at rebuilding cost, loss of rents, general liability, an umbrella and flood where it applies. What changes with a portfolio is how the limits, deductibles and paperwork fit together.

For a short overview of how we approach multi-property owners, see our commercial real estate portfolios page.

Should All Your Properties Be on One Policy?

Often, but not always. Many owners move to one master program, meaning one set of policies that covers every property. Others keep a separate policy for each property. Both approaches have real trade-offs.

When Does a Separate Policy Make Sense?

Some properties fit poorly in a combined program. Common examples:

• A coastal building. A property near the coast may need wind written separately, and its storm risk can change the terms for the whole program.
• An apartment property. Underwriters often treat apartments as a habitational risk with their own pricing and rules, and that market has stayed more selective.
• Outside partners. A property owned with investors who don't share in the others may be cleaner on its own policy.
• A lender's rules. Some loan documents limit shared policies or require extra wording before they accept blanket coverage.

We usually price both ways and show you the difference in limits, deductibles and terms, not just the premium.

How Do Blanket Limits Differ From Per-Building Limits?

With a scheduled limit, each building has its own limit. With a blanket limit, one total limit covers several buildings, so a large loss at one property can draw on the shared amount. That helps if one building's value was set too low.

Blanket limits come with conditions. Insurers usually want a signed statement of values, and many add a margin clause. A margin clause caps what you can collect at one location at a set percentage of the value you reported for it, such as 110% or 125% (IRMI). With a tight margin clause, a blanket limit works a lot like a per-building limit.

Margin clauses are not a standard form, so the name, the percentage and the wording vary from policy to policy. Ask where yours sits and what percentage it uses before you sign off on your values.

How Do You Keep Your Statement of Values Current?

Update it at every renewal, and any time you buy, sell or renovate. Your statement of values is the spreadsheet that lists each building with its address, use, size, construction, year built and values. Insurers price your program from it, and margin clauses and percentage deductibles are often tied to it.

Each value should show what the building would cost to rebuild today, called its replacement cost. That isn't what you paid, its market value or its tax appraisal. A purchase price includes land and reflects rent, so it can be far above or below the cost to rebuild.

Coinsurance and Agreed Value

Most property policies have a coinsurance clause. If your limit is below a set share of the value at the time of loss, often 80% or 90%, the insurer cuts partial claims in proportion. With a blanket limit, coinsurance is usually measured against the total value of everything the blanket covers. Insurers may also ask for a higher percentage on blanket limits, such as 90% or 100%.

Agreed value suspends the coinsurance clause for the policy term when you insure to the values you reported. It doesn't raise your limit. It removes the penalty risk, and it usually needs a fresh signed statement of values at each renewal.

1. Get a building valuation for each building from a recognized estimating tool or an appraiser, and refresh it every few years.
2. Between valuations, adjust each value for changes in construction costs.
3. Add renovations, new roofs and any improvements you own.
4. List a year of rents for each property, so your loss of rents limit matches your real rent roll.
5. Keep a dated copy of each year's statement of values and the source of each number.

How Do Deductibles Add Up When One Storm Hits Several Buildings?

Quickly. Texas wind and hail deductibles are often a percentage of each building's insured value, and many policies apply them building by building. So one hailstorm that crosses a metro area can trigger several deductibles at once.

Read three things in your wording: the percentage, the value it applies to, and whether it applies per building, per location or per occurrence. Some policies use the building value only. Others use the total insured value at that location, including rents. Many also set a minimum dollar amount.

On the coast, a named storm deductible works the same way and is often larger. One hurricane can reach every property you own around Houston and Galveston Bay, and each building's deductible may apply.

Aggregate Deductibles and Buy-Downs

Some programs offer an annual aggregate deductible. Once you've paid a set total in deductibles during the policy year, later deductibles are reduced or waived, depending on the wording. Fannie Mae's multifamily guide even has its own section on aggregate deductibles (Fannie Mae).

Another option is a deductible buy-down, a separate policy that pays part of a large wind, hail or named storm deductible. It has its own terms and its own smaller deductible. Whether either option makes sense depends on its price compared with the gap it closes.

Set your deductibles from the worst storm you could face across all your properties, not the loss at one building. Then check the result against each lender's maximum deductible.

Should Every Property Renew on the Same Date?

For most growing portfolios, one common renewal date is easier to manage. But it isn't right for everyone. Weigh both sides:

• Less paperwork. One statement of values update, one round of underwriting questions, and one set of certificates and lender evidence.
• A clearer picture. You see your total limits, deductibles and costs in one place, and insurers see the whole account in one submission.
• Everything reprices at once. If the market tightens or a big storm hits just before your date, the whole portfolio feels it.
• Cash flow. One large premium may be due at once. Many owners use a premium finance agreement to spread payments.
• Getting there. Lining up dates usually means writing some policies for a shorter or longer term once. Ask how each insurer charges for that.

Whose Name Should Go on the Policy?

Every legal entity that owns a property should be on the policy. Many investors hold each property in its own LLC. In a combined program, each owning LLC is usually listed as a named insured, often along with the parent company and the property manager.

This matters at claim time. A property policy pays those with an insurable interest, and a claim check made out to the wrong entity can be delayed while names are sorted out. Lenders also check that the borrower on their loan matches a named insured.

• Match each name exactly to the deed and the loan documents.
• Tell your agent when you form, rename or dissolve an entity.
• Know who the first named insured is. That entity usually pays the premium and receives notices for everyone.
• Ask how the premium will be split by property if each LLC keeps its own books.

How Do You Handle Different Lenders' Requirements?

Track them loan by loan. Each lender sets its own insurance requirements for limits, deductibles, loss of rents, insurer ratings and the wording that protects the lender. Those rules can differ a lot within one portfolio.

• Agency loans. Apartments financed through Fannie Mae or Freddie Mac follow agency insurance requirements. Fannie Mae's multifamily guide has sections on blanket policies covering several properties, deductibles (Fannie Mae) and named storm insurance (Fannie Mae).
• CMBS loans. CMBS insurance requirements are written into the loan documents and enforced by a servicer. They are often detailed, may call for terrorism coverage, and can be slow to waive.
• Bank loans. Local and regional banks often have shorter lists, but they still set maximum deductibles and require the right lender wording.

Each lender usually wants to be named through a mortgagee clause for its own property and to receive evidence of property insurance at closing and at each renewal. On a blanket program, some lenders also ask to see that the shared limit is large enough for their property. If coverage falls short, a lender may buy force-placed insurance and bill you, so review insurance terms before you sign a new loan.

What Happens When You Buy or Sell a Property Mid-Term?

Tell your agent as soon as you're under contract. Don't count on automatic coverage. The standard building form has a newly acquired property extension, but it's small and short. IRMI describes it as up to $250,000 per building, lasting no longer than 30 days or the end of the policy (IRMI). It generally applies only to a building bought for a use similar to the buildings already insured, or for use as a warehouse.

That is far below the value of most commercial buildings. Some portfolio programs include a higher limit for new purchases, but the terms vary. The safer path is to add the property by endorsement before closing, so your lender gets its evidence of insurance on time.

• Send the address, use, size, year built, construction, roof age and rent roll.
• Get the new lender's insurance requirements early.
• Check the flood zone before closing. A new NFIP policy usually has a 30-day waiting period, but there is no wait when it's bought while making, increasing, extending or renewing a loan (FloodSmart).
• If the building is mostly empty, ask about the vacancy clause, which can shrink coverage once a building has been vacant for a set time.

When you sell, remove the property by endorsement as of the closing date. Keep liability in place until the deed transfers. Ask how any return premium is figured, and update the statement of values so your blanket limit and deductibles reflect what you still own.

How Should Liability and the Umbrella Work Across Properties?

Most portfolios use one general liability policy that lists every location, with one umbrella on top. The detail that matters most is the aggregate. The general aggregate limit is the most the policy pays for most claims in one policy year.

Without an endorsement, every property shares that one aggregate. A bad year at one apartment complex could use up the coverage your shopping center relies on. A per location aggregate endorsement, ISO form CG 25 04, applies the aggregate separately to each designated location (IRMI). Many lenders ask for it.

Then check the umbrella. It usually has one aggregate shared by every property, so size it for your total exposure: the number of properties, apartment units, visitors and parking lots. Ask how the umbrella's aggregate applies, because it may not follow a per location structure underneath it.

Loss Runs Follow You

Underwriters review loss runs for every property, usually for the past five years. In a combined program, one property with frequent claims can affect terms for all of them. Fixing that property's problem, and showing the fix in writing, helps the whole account.

How Do Coastal Wind and Flood Change a Texas Portfolio?

Underwriters look at where your values cluster, because one catastrophe can hit many buildings at once. A portfolio spread across Houston, Dallas and San Antonio has a different storm profile than one with every building near Galveston Bay.

Coastal Wind

The Texas catastrophe area covers the 14 first-tier coastal counties, plus areas of Harris County east of Highway 146 inside the city limits of La Porte, Morgan's Point, Pasadena, Seabrook and Shoreacres (TWIA). Private policies there often exclude wind and hail, and the Texas Windstorm Insurance Association (TWIA) is the insurer of last resort. A portfolio with coastal and inland buildings may end up with wind written separately for the coastal ones.

Very large or coast-heavy portfolios are sometimes insured through a shared and layered program, where several insurers each take part of the limit. Their storm deductibles and limits can work differently from a single policy, so model them carefully.

Flood

Standard property policies exclude flood. An NFIP commercial policy covers only one building, up to $500,000 for the building and $500,000 for contents. It pays at actual cash value and doesn't pay for lost income (FEMA). The same form also insures apartment buildings with five or more units, but their contents limit is $100,000 (FEMA).

So a portfolio usually needs a separate NFIP policy for each building that needs flood coverage. Owners of larger buildings often add excess flood or private flood coverage. Some property programs include a flood sublimit shared by every location for the year, so one flood can use up much of it. Check each property's flood zone, because lenders usually require flood coverage for buildings in high-risk zones.

What Do Underwriters Ask for, and How Do You Prepare?

Underwriters want to understand each building and the portfolio as a whole. A clean, complete package helps them price your properties as they really are.

1. A statement of values with each building's address, use, square footage, stories, year built, values, and COPE details: construction, occupancy, protection and exposure.
2. Roof type, age and the date of any replacement for each building.
3. Rent rolls or occupancy for each property, including any building that is empty or mostly empty.
4. Current policies, declarations pages and renewal dates.
5. Five years of loss runs for each property.
6. The owning entity and the lender for each property, with each lender's insurance requirements.
7. Sprinkler, alarm and security details, and recent updates to wiring, plumbing and HVAC.
8. Planned purchases, sales and major renovations for the coming year.
