The quick read: A bridge loan on a Madison apartment building is short-term, floating-rate debt that funds the purchase plus a renovation or lease-up budget, then gets repaid by a permanent bank or agency loan once the building's income is stabilized. The lender sizes it on today's value and on the stabilized value, and the refinance math decides whether the plan works. In 2025 the Madison metro permitted 129 buildings of five or more units carrying 5,008 units, according to the Census Bureau.
How do bridge loans work on Madison apartment buildings?
A bridge loan on a Madison apartment building funds the purchase plus a renovation or lease-up budget, usually charges interest only while the business plan runs, and is repaid at maturity by a permanent loan or a sale once occupancy and rents support the new debt. The term is short, so the exit is the underwriting.
The investor's first decision is the building and the plan, not the loan. Three plans show up in Madison: an older walk-up on the Near East Side or around Schenk-Atwood that needs kitchens, baths and flooring; a building near campus leased by the bed on an academic calendar; and a suburban complex in Middleton or Fitchburg with rents below the renovated comps. Each plan changes what a bridge loan has to carry.
The loan itself usually has three parts:
- Initial funding: a share of the purchase price, released at closing.
- Renovation holdback: the capital budget, drawn against completed and inspected work.
- Interest reserve: cash set aside to pay interest while income is below debt service, where the lender requires one.
Maturity is short, often with extension options that carry fees and performance tests. When the renovated units are leased at the new rents, a permanent lender refinances the bridge balance. For the national picture across lender types, see our guide to multifamily bridge loans.
How much apartment construction does the Madison metro permit?
The Madison metro permitted 129 new buildings of five or more units in 2025, carrying 5,008 units, according to the Census Bureau's Building Permits Survey metro file. That works out to about 38.8 units per building, and five-plus buildings held about 72% of all new units permitted in the metro.
Madison, WI metropolitan area (CBSA 31540) new residential building permits, 2025, Census Bureau Building Permits Survey CBSA annual file (metro, not city; permit authorizations, not completions; value in thousands of dollars):
| Building size | Buildings | Units | Permit value ($ thousands) |
|---|---|---|---|
| Building size 1 unit | Buildings 1,725 | Units 1,725 | Permit value ($ thousands) 843,785 |
| Building size 2 units | Buildings 93 | Units 186 | Permit value ($ thousands) 39,329 |
| Building size 3-4 units | Buildings 7 | Units 28 | Permit value ($ thousands) 6,416 |
| Building size 5 or more units | Buildings 129 | Units 5,008 | Permit value ($ thousands) 839,041 |
Five-plus units, Madison metro, 2025: 129 buildings and 5,008 units, per the Census CBSA file.
Units per five-plus building (our arithmetic): 5,008 divided by 129 is about 38.8.
Five-plus share of new units (our arithmetic): 5,008 of 6,947 total units, about 72%.
Permit value per five-plus unit (our arithmetic): $839,041 thousand divided by 5,008 units is about $167,540. That is the valuation reported on permits, not a full development budget.
For a bridge borrower, the reading is competition. New five-plus buildings lease up in the same years a renovated older building is trying to push rents, and a bridge lender will ask how the renovated units price against new product nearby. Bring rent comps from both.
What does a bridge lender underwrite on a Madison apartment building?
A bridge lender underwrites two sets of numbers on a Madison apartment building, the as-is value and income today and the as-stabilized value and income after the plan, and sizes the loan to the tighter of its limits on each before checking that stabilized income can support a permanent loan.
Sponsor: completed renovations, local management experience and liquidity. Lenders want to see the same plan executed before.
Budget: a line-item capital plan per unit, with contractor bids and a contingency.
Rents: in-place rent roll, trailing operating statements, and comps for renovated units.
Lease-up schedule: how many units turn each month, and when the building reaches stabilized occupancy.
Rate: bridge debt often floats over an index such as SOFR, which was 3.87% on 2026-10-08, per the FRED series SOFR. Ask each lender for the spread, the floor and whether it requires a rate cap.
Exit: the permanent loan you expect, sized at today's permanent rates, and whether it repays the full bridge balance.
How does Freddie Mac's Value-Add loan compare with a private bridge loan?
Freddie Mac's Optigo Value-Add loan is a published agency version of a bridge: a three-year floating-rate, full-term interest-only loan for light renovations of $10,000 to $25,000 per unit, sized at baseline 85% as-is and 75% as-stabilized loan-to-value, though its term sheet excludes student housing.
The terms below come from Freddie Mac's Value-Add term sheet dated 04/25. They apply to that program only, through Freddie Mac's Optigo lenders, and Freddie Mac says terms are subject to change without notice. Private bridge terms vary by lender and this guide has no public, dated source for them, so each cell in that column is a question to ask.
Freddie Mac Value-Add terms (term sheet dated 04/25) versus a private bridge lender (no public, dated source):
| Feature | Freddie Mac Value-Add | Private bridge lender |
|---|---|---|
| Feature Term | Freddie Mac Value-Add Three years, one 12-month borrower extension, one optional 12-month extension at Freddie Mac's discretion | Private bridge lender Ask for term and extension tests |
| Feature Rate | Freddie Mac Value-Add Floating, full-term interest-only, no rate cap required | Private bridge lender Ask for index, spread, floor and cap |
| Feature Renovation budget | Freddie Mac Value-Add $10,000 to $25,000 per unit; 50% of budget should be spent on unit interiors | Private bridge lender Ask for the maximum budget and draw process |
| Feature As-is sizing | Freddie Mac Value-Add Baseline 85% loan-to-value and 1.15x amortizing coverage, subject to market adjustment | Private bridge lender Ask for as-is loan-to-value and loan-to-cost |
| Feature Stabilized sizing | Freddie Mac Value-Add Baseline 75% loan-to-value and 1.30x coverage, subject to market adjustment | Private bridge lender Ask for the as-stabilized test |
| Feature Student housing | Freddie Mac Value-Add Not eligible | Private bridge lender Ask whether by-the-bed leases are accepted |
| Feature Recourse | Freddie Mac Value-Add Non-recourse | Private bridge lender Ask for guaranty and carve-out terms |
| Feature Exit | Freddie Mac Value-Add 1% exit fee, waived on refinance with a qualified Freddie Mac Conventional loan | Private bridge lender Ask for exit fees and prepayment terms |
Equity: 15% cash equity generally required, per the term sheet.
Renovation timing: work must begin within 90 days of origination and finish within 33 months.
Extension fees: 0.5% for the borrower extension and 1% for the Freddie Mac extension.
One more change matters for small Madison buildings. Freddie Mac's SBL Guide Addendum, effective September 25, 2026, says Freddie Mac "is no longer accepting Small Balance Loan ('SBL') Mortgage applications as of April 30, 2026." A bridge plan written around that small-loan exit needs a new takeout, so ask each permanent lender which program it would use today.
How does a Madison bridge loan exit to a permanent loan?
A Madison bridge loan exits when the stabilized building qualifies for a permanent loan large enough to repay the bridge balance, and in the illustrative 24-unit case below the permanent lender's debt service coverage test, not the appraised value, sets the refinance amount and leaves a gap to fund.
Every figure below is our arithmetic on assumed inputs, not a quote, a market rent or a lender term.
Illustrative (our arithmetic) cost: a 24-unit building bought for an assumed $3,600,000, plus an assumed $20,000 per unit of renovation ($480,000), is $4,080,000.
Illustrative (our arithmetic) bridge loan: an assumed 75% of total cost is $3,060,000, with $2,580,000 funded at closing and the $480,000 holdback drawn as work finishes. Equity is $1,020,000.
Illustrative (our arithmetic) carry: at SOFR of 3.87% plus an assumed 4.00% spread, the rate is 7.87%. Interest on the $2,580,000 initial balance is $203,046 a year; an assumed as-is net operating income of $200,000 covers it about 0.98x, so an interest reserve fills the gap. Fully drawn, interest is $240,822 a year.
Illustrative (our arithmetic) stabilized income: an assumed $260,000 of net operating income after renovation is an 8.5% debt yield on $3,060,000.
Illustrative (our arithmetic) value test: at an assumed 6.00% cap rate the building is worth $4,333,333, and an assumed 75% permanent loan-to-value allows $3,250,000. Value clears the bridge balance.
Illustrative (our arithmetic) coverage test: at an assumed 6.25% rate on 30-year amortization (a 7.39% annual constant) and an assumed 1.25x coverage, $260,000 supports $208,000 of debt service, or about $2,815,100 of loan. That is about $244,900 short of the bridge balance.
Illustrative (our arithmetic) breakeven: repaying the full $3,060,000 needs about $282,600 of net operating income, about $22,600 more, or roughly $79 a month per unit.
The lesson for an investor: run the exit at today's permanent rate before you close the bridge. If coverage binds, either the rent plan carries more income, the bridge carries less leverage, or you budget cash to close the gap at refinance.
How do Wisconsin rental laws affect a Madison bridge business plan?
Wisconsin law shapes a Madison bridge business plan in two ways a lender reads: state statute section 66.1015 bars any city from regulating the amount of rent, and section 66.0104 bars local ordinances that stop a landlord from signing or showing a unit to the next tenant during a current tenancy.
Rent regulation: "No city, village, town or county may regulate the amount of rent or fees charged for the use of a residential rental dwelling unit," per Wis. Stat. 66.1015(1). A post-renovation rent increase is set by the market, not a local cap. The lender still sizes on comps, not on what the law allows.
Pre-leasing: Wis. Stat. 66.0104(2)(a)3 and 4 bar ordinances that prohibit or limit entering into a rental agreement with, or showing a unit to, a prospective tenant during the current tenancy. That protects the early signing cycle a by-the-bed campus building runs for the next academic year.
Inspections: Wis. Stat. 66.0104(2)(e)1 allows required rental inspections only on complaint, under a permitted inspection program, under s. 66.0119, or as state or federal law requires. Budget for code work either way.
Campus demand: UW-Madison reported preliminary fall 2026 enrollment of 50,965 and an incoming undergraduate class of 9,781, in a university news release dated September 25, 2026.
For a campus building, the financing question is program eligibility, not demand. Freddie Mac's Value-Add term sheet lists student housing as not eligible, so a by-the-bed plan needs bridge and permanent lenders that underwrite student housing. Ask each one before you sign a purchase contract.
What should a Madison investor have ready before asking for bridge terms?
A Madison investor should have the purchase contract, rent roll, trailing operating statements, a unit-by-unit renovation budget, renovated rent comps, a lease-up schedule and a priced permanent exit ready before asking for bridge terms, because every lender sizes on today's income and tomorrow's income at once.
- Purchase contract: price, deposit and closing date.
- Rent roll and operating statements: in-place leases, concessions and the last 12 months of income and expenses.
- Renovation budget: cost per unit, scope by unit type, contractor bids and contingency.
- Rent comps: renovated units and new buildings nearby, by unit type.
- Lease-up schedule: units turned per month and the target stabilization date; for campus product, the academic-year signing calendar.
- Sponsor package: schedule of real estate owned, personal financial statement and completed renovation history.
- Exit plan: the permanent program you expect, sized at current rates, with any shortfall funded.
