Whether utilities are individually metered or master-metered makes a big difference. If each unit has its own utility meters, tenants can handle their own utility bills, so the landlord doesn't have to worry about paying them. But if the utilities are on a master meter, the landlord has to cover those costs. In that case, it's important to check out the T-12 (trailing 12 months) financial statements.
Looking at the T-12 is key because utility costs can vary a lot from one property to another. For example, single-pane windows can make heating and cooling more expensive compared to double-pane windows. So, it's a good idea to really dig into the T-12. If the property is master-metered, consider setting up a RUBS (Ratio Utility Billing System) program to bill back some of the costs. Just be aware of your state's laws, as they can differ on how much you can bill back to tenants. If the property is mastered metered, I use the total utility bill from the T-12 as the estimate in my pro forma.
