Which type of bonds are specifically not subject to the same limitations as general obligation bonds?

Revenue bonds are a type of bond that are specifically not subject to the same limitations as general obligation bonds because they are secured by the revenue generated from a specific project or source, rather than the full taxing power of the issuing entity. General obligation bonds are backed by the issuer's ability to tax its residents, which imposes strict limitations on how much debt an issuer can take on because it must maintain a certain level of tax capacity.

In contrast, revenue bonds have the unique advantage of being tied solely to the revenues generated from particular projects, such as toll roads, utilities, or other facilities. This means that issuers can potentially take on more debt, as the repayment is dependent on the project's revenue rather than the overall financial condition of the issuer. This allows for a more flexible approach to funding specific projects without directly affecting the issuer's credit rating in relation to its general obligation debt.
