The quick read: Bridge financing on a Des Moines apartment building should be judged on whether the permanent refinance at the end of the term will close, and in Iowa that refinance runs on a tax line that can change mid-loan. Iowa reassesses real property every odd-numbered year, the next assessment is set as of January 1, 2027, and bills on it come due in September 2028, about when a bridge loan closed today would be paying off. Test the exit DSCR against reassessed taxes, using the 44.5345% residential rollback and the parcel's Polk County district levy, and check whether a conversion will be taxed as commercial or residential. Then compare quotes on leverage, reserves, extension tests and prepayment.
What are the options for bridge financing a Des Moines apartment building?
The main options for bridge financing a Des Moines apartment building are local and regional banks, debt funds and private bridge lenders, and they differ less on headline rate than on how much renovation money they advance, how they test extensions and how much recourse they want. Pick the structure the exit can support.
Corporate Finance Institute's bridge loan explainer (updated November 20, 2025) defines a bridge loan as a short-term form of financing used to meet current obligations before securing permanent financing, with relatively high interest rates and collateral such as real estate. In Des Moines the bridge request usually comes from one of three plans:
- Sherman Hill and Ingersoll-Grand rehab-to-stabilize. An older, partly occupied building gets renovated unit by unit, and the loan funds turns and capital work while rents move up.
- East Village and downtown conversions. An office or commercial building becomes apartments, so the loan carries construction, a certificate of occupancy and a lease-up.
- Lease-up of newer product. A recently completed building needs time to reach the occupancy a permanent lender requires.
All three end at a refinance. Fannie Mae's Small Mortgage Loan Program term sheet is a useful public benchmark for that exit: existing, stabilized properties with 5 or more units, loans up to $9 million, a maximum LTV of 80% and a minimum DSCR of 1.25x. Other permanent lenders set their own tests.
What does the Des Moines permit pipeline say about bridge deal size?
Census permit data show that the Des Moines metro builds apartments in large buildings, averaging close to 47 units each in 2025, which means a bridge request for an older 10-to-60-unit rehab competes for lender attention with much larger lease-up loans. Size the lender search to the actual loan.
The Census Bureau's 2025 annual Building Permits Survey file for the Des Moines-West Des Moines metro shows 57 buildings of five or more units carrying 2,675 units. Inside the City of Des Moines, the 2025 place file shows 16 such buildings with 1,377 units, an average above 80 units per building. New construction is concentrated in big projects, so the rehab-to-stabilize market in Sherman Hill and Ingersoll-Grand is mostly about existing buildings that are smaller and older.
That affects lender fit. A $3 million rehab loan on a 30-unit building is a natural size for a local bank or a smaller debt fund, while a $20 million lease-up loan goes to a different set of lenders. Fannie Mae's small-loan program tops out at $9 million, which makes it a realistic take-out for many rehab deals but not for the largest new buildings.
How does Iowa's two-year reassessment reprice the tax line mid-bridge?
Iowa's two-year reassessment reprices the tax line mid-bridge because the state revalues real property every odd-numbered year and bills on each new value arrive two years later, so a 24-to-36-month bridge loan closed in late 2026 will refinance on the 2027 assessment, not on today's bill. The exit lender will see it.
The Iowa Legislative Services Agency's January 7, 2026 explainer sets out the cycle: real property is assessed every odd-numbered year, the assessment year is the January 1 valuation, and bills are due in the fall and spring two years after the assessment year. The 2025 assessment is being paid in September 2026 and March 2027. The 2027 assessment will be paid in September 2028 and March 2029.
The rollback limits the statewide average, not your parcel. The same explainer says aggregate residential taxable value growth from revaluation is capped at 3.0% per year, and the Department of Revenue sets the rollback to enforce it; for the 2025 assessment the residential rollback is 44.5345%. The LSA's rollback table shows it fell from 56.4919% for the 2022 assessment to 46.3428% for 2023, the kind of drop the state imposes when values rise far faster than 3%. A building whose value rises faster than the statewide residential average, which is exactly what a successful renovation produces, still sees its taxable value climb.
Why does tax class matter for a Des Moines conversion?
Tax class matters for a Des Moines conversion because an office or retail building is taxed as commercial property, with most of its value taxed at 90%, while an apartment building now takes the much lower residential rollback, so the in-place bill and the stabilized bill can differ by half. Model both.
The LSA explainer says that beginning with the 2022 assessment, properties from Iowa's former multiresidential class were combined into the residential class, so a typical apartment building is now residential for tax purposes. Commercial property follows a two-tier rule: the Department of Revenue's 2025 order taxes the first $150,000 of each commercial property unit at 44.5345% and the value above $150,000 at 90%. Confirm with the assessor when a converted building will be reclassified and how a mixed-use ground floor will be treated, because the class decides which rollback applies.
How should a lender test the exit DSCR on reassessed taxes?
The exit DSCR should be tested by taking the stabilized net operating income before taxes, subtracting the tax on a reassessed value at the residential rollback and the parcel's district levy, and dividing by the permanent loan's debt service. If the deal clears 1.25x only on today's bill, it does not clear.
The table uses an illustrative 40-unit building in the Ingersoll Grand self-supported municipal improvement district, where Polk County's consolidated levy for 2025 assessed valuations is 45.99496 per $1,000 of taxable value. Stabilized NOI before property tax is assumed at $520,000. The rollback is held at 44.5345%, because the 2027 figure is not yet known.
Illustrative exit test on a 40-unit Ingersoll-Grand building (hypothetical figures):
| Line | 2025 value, residential | 2027 value up 10% | 2027 value up 20% | 2025 value, taxed as commercial |
|---|---|---|---|---|
| Line Assessed value | 2025 value, residential $5,000,000 | 2027 value up 10% $5,500,000 | 2027 value up 20% $6,000,000 | 2025 value, taxed as commercial $5,000,000 |
| Line Taxable value | 2025 value, residential $2,226,725 | 2027 value up 10% $2,449,398 | 2027 value up 20% $2,672,070 | 2025 value, taxed as commercial $4,431,802 |
| Line Annual tax at 45.99496 | 2025 value, residential $102,418 | 2027 value up 10% $112,660 | 2027 value up 20% $122,902 | 2025 value, taxed as commercial $203,841 |
| Line NOI after tax | 2025 value, residential $417,582 | 2027 value up 10% $407,340 | 2027 value up 20% $397,098 | 2025 value, taxed as commercial $316,159 |
| Line Maximum debt service at 1.25x | 2025 value, residential $334,065 | 2027 value up 10% $325,872 | 2027 value up 20% $317,679 | 2025 value, taxed as commercial $252,928 |
At an illustrative 7.5% loan constant, the gap between the first and third columns is about $218,000 of permanent loan proceeds. The last column shows why a conversion must be underwritten on its residential class: the same value taxed as commercial supports roughly $1.1 million less debt at that constant. If the bridge loan is sized to the most optimistic column, the payoff can come up short.
What criteria separate one Des Moines bridge quote from another?
Des Moines bridge quotes should be compared on the same seven criteria, because a lower rate can hide a smaller initial advance, a thin interest reserve or an extension test that the reassessed tax line will fail in 2028. Ask each lender to fill in the same list.
Exit test: stabilized DSCR on a reassessed 2027 value, residential rollback and the parcel's district levy Leverage: initial advance and total loan, stated as loan-to-cost and as-stabilized loan-to-value Future funding: how renovation or conversion dollars are drawn, inspected and released Interest reserve: months covered, and whether it assumes a lease-up schedule you can document Extension: number of options, fee for each, and the DSCR or debt-yield test each one requires Prepayment: minimum interest or exit fee if the refinance closes early Recourse: completion guarantee and carve-outs, especially on conversions
The extension test deserves the closest reading. An extension measured on trailing NOI in late 2028 will be measured after the first bill on the 2027 assessment has posted. Our guides to LTV versus LTC on a bridge loan and how long a commercial bridge loan term should be cover the leverage and term questions in more depth.
How do you get Des Moines bridge lenders competing for the deal?
You get Des Moines bridge lenders competing by sending each one the same complete package, including the parcel's tax class, district levy and a stabilized pro forma stressed for the 2027 reassessment, so that the quotes they return can be compared line by line. YieldStack is a commercial mortgage brokerage.
YieldStack's software matches the deal against a catalog of 20,000+ loan programs, which is a count of programs, not of lenders. Human brokers then structure the request, negotiate for the borrower and carry the deal toward closing. Every credit decision is made by the lender; YieldStack arranges the introductions and negotiates on the borrower's side, and no loan, rate, or closing is guaranteed.
What to send:
- Property address, Polk County parcel number, tax class and district, and the current gross tax
- A current rent roll, trailing twelve-month operating statement and vacancy history
- The renovation or conversion budget, schedule and permit status
- A stabilized pro forma with taxes at the residential rollback, stressed for a higher 2027 assessment
- Purchase contract or payoff statement, target loan amount and the intended permanent exit
- Sponsor track record on comparable rehabs, conversions or lease-ups
The Des Moines market hub collects our local material; it is not a promise of any particular lender or term. When the package is ready, send the deal for review. It costs Zero upfront to submit a deal and review offers; YieldStack's broker fee is 0.50–1.00% of the loan amount and is paid only at closing.
The bottom line
A Des Moines bridge loan is only as good as its refinance, and the refinance will be underwritten on the 2027 assessment. Model the stabilized building at the residential rollback and its district levy, stress the value upward, confirm the tax class on any conversion, and compare quotes on leverage, reserves and extension tests before rate.
