Bond Financing for Commercial Projects

Bond financing lets a project borrow from the capital markets rather than from a single lender, often at a lower rate because the interest is exempt from federal income tax, in exchange for a public approval process, higher issuance costs and ongoing compliance. Manufacturers, nonprofits, hospitals, schools, affordable housing developers and infrastructure sponsors use it. This guide explains how bond financing works, the main kinds of bonds, who qualifies, what it costs, how it compares with bank and conduit loans, and how to approach it.

How Bond Financing Works

A bond is a loan sold in pieces. Instead of one lender advancing the money, a public issuer, such as a state or local development authority, issues bonds that investors buy. The proceeds fund the project. The borrower, through a loan or lease agreement with the issuer, makes payments that the issuer passes to a trustee, who pays the bondholders. In a conduit issuance, which is how most private projects are financed, the issuer lends its name and tax-exempt status but takes no credit risk; investors look only to the project and the borrower.

Bonds are either tax-exempt, where interest paid to bondholders is excluded from federal income tax and sometimes state tax, or taxable. Tax exemption is available only for purposes Congress has approved, which is why the first question in any bond financing is whether the project qualifies.

Kinds of Bonds Used for Commercial and Nonprofit Projects

Industrial Revenue Bonds

Industrial development or industrial revenue bonds finance manufacturing facilities: the purchase of land, construction or expansion of a plant, and the equipment inside it. Federal rules limit the size of tax-exempt manufacturing issues, generally to ten million dollars per project with limits on capital spending at the site over a six-year window, so these bonds suit small and mid-sized manufacturers rather than the largest plants. They require an allocation of the state’s annual private activity bond cap, which is competitive in some states and freely available in others.

Bonds for Nonprofits

Organizations exempt under section 501(c)(3), such as hospitals, universities, private schools, museums and cultural institutions, can finance facilities with tax-exempt bonds without the size limits that apply to manufacturers. The project must serve the organization’s exempt purpose, and private business use of the facility is restricted.

Multifamily Housing Bonds

Private activity bonds for rental housing finance affordable apartments and trigger 4% tax credits; see our affordable housing financing guide.

Exempt Facility Bonds

Airports, docks, water and sewage facilities, solid waste disposal, certain energy facilities and other infrastructure defined by federal law can be financed with tax-exempt bonds even when privately owned or operated.

Taxable Bonds

Projects that do not qualify for tax exemption can still access the bond market with taxable bonds, which carry higher rates but avoid the use restrictions and some of the compliance. Large real estate and corporate projects use them when the amount justifies the cost of a public offering or a private placement.

Tax Increment and Special District Bonds

Some public bodies issue bonds repaid from the increase in property taxes that a development generates, or from assessments on a special district, to fund infrastructure that benefits a private project. The developer does not borrow directly, but the financing shapes the project’s economics.

Who Qualifies

Qualification depends on the bond type: manufacturers for industrial revenue bonds, 501(c)(3) organizations for nonprofit bonds, affordable housing developers for housing bonds, and specific infrastructure for exempt facility bonds. Beyond eligibility, the project needs enough credit quality to attract investors or a bank willing to buy or enhance the bonds. Bond financing rarely makes sense below a few million dollars because issuance costs are fixed; five million dollars is a common practical floor, and many issuers prefer larger deals.

Credit Enhancement and Private Placement

Investors in a public bond offering want a rating or a guarantee. Most private project bonds are therefore either:

• Enhanced by a bank letter of credit, which guarantees payment to bondholders. The bank underwrites the borrower like a loan, charges an annual fee, and typically requires a shorter commitment, five to seven years, than the bond term, creating renewal risk. Variable-rate demand bonds, which reset weekly and can be tendered back, use this structure.
• Privately placed with a bank, which buys the whole issue and holds it as a tax-exempt loan. This removes the rating and marketing cost, keeps the tax exemption and simplifies the structure. The bank’s rate reflects the tax-exempt income and the borrower’s credit.
• Rated and sold publicly, for larger, stronger borrowers such as hospital systems, universities and established companies, usually at a fixed rate for a long term.

What Bond Financing Costs

The attraction is the rate: tax-exempt interest can run meaningfully below a comparable taxable loan, because the lender or investor pays no federal tax on it. Against that saving come costs a bank loan does not have: bond counsel, issuer’s counsel, underwriter or placement agent fees, the issuer’s application and annual fees, a trustee, a rating if public, a letter of credit fee if enhanced, and the borrower’s own counsel and accountants. Issuance costs of two to four percent of the bond amount are typical, and federal rules cap how much of the proceeds can pay them. The lower rate wins when the bonds are large enough and outstanding long enough for the interest savings to exceed the up-front cost; a rule of thumb is a project above five million dollars with a term of ten years or more.

The Process and the Timeline

1. Preliminary review. The borrower, bond counsel and the issuer confirm eligibility and structure.
2. Inducement resolution. The issuer adopts a resolution expressing intent to issue; costs incurred after this date can generally be reimbursed from bond proceeds, so timing matters.
3. Volume cap allocation, if required, from the state.
4. Public approval. Federal law requires a public hearing and approval by an elected official or body for private activity bonds, with published notice.
5. Credit. A bank commits to buy or enhance the bonds, or an underwriter markets them.
6. Documents. The indenture, loan or lease agreement, letter of credit or purchase agreement, tax certificate and opinions.
7. Closing. Bonds are issued, proceeds are deposited with the trustee, and draws fund the project.

Expect three to six months from preliminary review to closing on a straightforward deal, longer if volume cap is competitive or the public approval calendar is slow.

Fixed or Variable: Structuring the Rate

Tax-exempt bonds can carry a fixed rate for the full term, which locks the cost but limits prepayment, or a variable rate that resets weekly or monthly, which is lower on average but exposes the borrower to rate movement and, with demand bonds, to the risk that bonds tendered back cannot be remarketed. Many borrowers with variable-rate bonds buy an interest rate swap to fix the cost; the swap is a separate contract with its own counterparty, collateral and termination costs, and it is where several borrowers have been surprised in past rate cycles. Bank private placements often offer a fixed rate for an initial period, say ten years, with a reset after; ask what happens at the reset and whether the bank can simply decline to continue.

Equipment and Working Capital Through Bonds

Bond proceeds can finance equipment as part of a facility project, and some issuers run small-issue equipment programs for manufacturers. Working capital generally cannot be financed with tax-exempt bonds; the proceeds must go to capital assets. Borrowers who need both typically pair bonds for the facility and equipment with a conventional line of credit for working capital, from the same bank when the bank is the bond purchaser.

Refunding and Prepayment

Bonds can often be refinanced with new bonds, called a refunding, when rates fall, subject to tax rules that limit advance refundings of tax-exempt debt. Prepayment of a privately placed bond follows the bank’s terms, which may include a make-whole provision; a publicly sold fixed-rate bond usually cannot be called for a period of years and then only at a premium. Build the prepayment terms into the comparison with a bank loan, because a borrower who may sell the facility in five years can pay dearly to unwind a fifteen-year bond.

Working With the Issuer

Local and state development authorities exist to do this work and are usually helpful. They publish application forms, fee schedules and approval calendars; their staff can tell you quickly whether a project fits and which bond counsel firms are active in the state. Some issuers also run related programs, such as sales tax exemptions on construction materials or property tax abatements through a lease structure, that can be combined with the bonds. Ask about every program the issuer offers before deciding on the structure.

Compliance After Closing

Tax exemption comes with rules that last as long as the bonds. The borrower must use the facility for the qualifying purpose, limit private business use, track and spend proceeds within required periods, calculate and rebate to the federal government any investment earnings above the bond yield, and file reports. Breaching the rules can make the bonds taxable retroactively, which is an event of default. Borrowers appoint a compliance officer and keep bond counsel’s post-issuance compliance checklist in the file.

When Bond Financing Makes Sense

• A manufacturer building or expanding a plant within the size limits, in a state with available volume cap.
• A nonprofit financing a facility it will own and use for its mission.
• An affordable housing developer who needs the 4% credits that bonds unlock.
• An infrastructure or energy project that fits an exempt facility category.
• Any borrower large enough that the rate savings outweigh the issuance cost and the compliance burden.

When It Does Not

• Projects under a few million dollars.
• Short holds or projects likely to be sold or refinanced within a few years.
• Facilities with significant private business use that would break the tax rules.
• Borrowers without the staff or advisers to manage compliance.
• Tight timelines that cannot absorb the approval calendar.

A Worked Example

A manufacturer plans an $8 million expansion: a $5 million building addition and $3 million of equipment. The state development authority confirms eligibility for industrial revenue bonds and allocates volume cap. The company’s bank agrees to buy the bonds in a private placement at a tax-exempt rate roughly a point and a half below its taxable commercial loan rate, for a fifteen-year term with twenty-year amortization. Issuance costs, including bond counsel, issuer fees and the bank’s fee, come to about $220,000. Over fifteen years the interest savings on $8 million exceed that cost several times over. The company appoints its controller as compliance officer, keeps capital spending at the site within the federal limit for the required period, and files annual reports. The alternative, a conventional bank loan, would have closed two months sooner at a higher rate with no compliance burden; for a company that intends to stay in the plant for decades, the bonds win.

Preparing the Application

Issuers and banks ask for the same core package: three years of financial statements and the current interim, a project budget with contractor bids and equipment quotes, a description of the facility and its use, the number of jobs created or retained (many issuers score on it), evidence of site control, environmental reports, and the borrower’s organizational documents. Nonprofits add their determination letter and a description of how the facility serves the exempt purpose. Have bond counsel review the project description before it is submitted; the words used to describe the facility’s use can decide eligibility, and a description written for marketing can accidentally create private business use.

Questions to Ask

1. Does my project qualify for tax-exempt bonds, and under which category?
2. Is volume cap required, and is it available this year?
3. What are the total issuance costs, itemized, and what portion can bond proceeds pay?
4. Will the bonds be privately placed, enhanced or publicly sold, and what rate does each imply?
5. What is the term, the amortization and the prepayment provision?
6. If a letter of credit is used, what is its term and renewal risk?
7. What compliance will we have to manage, and who will help us?
8. What is the realistic timeline to closing?

Two Shorter Examples

A private school needs a $12 million academic building. As a 501(c)(3), it qualifies for tax-exempt bonds with no size cap. Its bank buys the bonds in a private placement at a tax-exempt rate fixed for ten years with a twenty-five-year amortization, secured by a mortgage on the campus and a covenant to maintain a minimum level of unrestricted cash. The school’s finance committee adopts a post-issuance compliance policy, because a summer camp run by an outside operator in the new building would be private business use and needs to be measured against the limits.

A food processor wants a $3 million equipment line. Bond counsel confirms eligibility, but the issuer’s fees, counsel and the bank’s placement fee would consume more than the rate savings over the equipment’s seven-year life. The company takes a conventional equipment loan instead and keeps bonds in mind for the next plant.

Terms Explained

• Issuer: the public body that issues the bonds.
• Conduit issuance: an issuance in which the issuer takes no credit risk; investors look to the borrower.
• Private activity bond: a tax-exempt bond issued for a private project in an approved category.
• Volume cap: the annual limit on private activity bonds each state may issue.
• Inducement resolution: the issuer’s statement of intent that starts the reimbursement clock.
• Letter of credit: a bank guarantee of payment to bondholders.
• Private placement: sale of the whole issue to one buyer, usually a bank.
• Trustee: the institution that holds proceeds and pays bondholders.
• Arbitrage rebate: the requirement to pay the federal government investment earnings above the bond yield.
• Private business use: use of a bond-financed facility by a private party, limited by federal rules.

Finding Lenders and Advisers

Bond deals need bond counsel, an issuer and a bank or underwriter. Banks that buy or enhance tax-exempt bonds say so, and many list it as a specialty. On LenderMatrix, lenders publish the loan types and uses they finance, including manufacturing facilities, nonprofit property and affordable housing, with their states and loan sizes; filter for lenders that fit your project and ask each whether it participates in bond financings. Describe the project once with Get Funding to see which programs’ published criteria it meets. LenderMatrix is a marketplace, not a lender; nothing here is legal, tax or financial advice, and bond eligibility is a legal question for bond counsel.

Summary

Bond financing trades up-front cost and ongoing compliance for a lower rate over a long term, and it is available only to projects the tax law favors: manufacturing, nonprofit facilities, affordable housing and infrastructure. For a large project held for many years by an organized borrower, it can be the cheapest money available. For a small project, a short hold or a thin team, a bank loan is simpler and often cheaper all in. Start with bond counsel and the issuer, confirm eligibility and cost, and compare the whole structure against a conventional loan before committing.
