If that is the case, then mortgage interest on a note is passive and not subject to UBIT.UBIT applies when a tax-exempt entity engages in a trade or business on a regular or repeated basis.Passive income not subject to UBIT includes royalties, dividends, interest, rent from real property and gains on the sale of an asset that has been held to produce such passive income.Trade or business subject to UBIT generally consists of services or buy/sell transactions.
