There many ways in real estate to model non-revenue units. Here at Top Shelf Models we model non-revenue units as a negative income line item. A non-revenue percentage is applied to all positive forms of income and the result is a negative income line item. Typically, non-revenue units are anywhere from 0.5%-2% depending on the number of non-revenue units as well as the size of the apartment complex. For example, what will happen if a multifamily project produces $300,000 of positive income in one month and a 1% non-revenue percentage is applied?
Non-Revenue Unit = $300,000 X 1% = $3,000
The non-revenue unit negative income for that month would be $3,000. Be sure to include this as a negative line item in the EGI.
