Flat utility fee versus bill-back on a three room house, and how much the choice moves the numbers
Take a 3 bed 1.5 bath house in a working neighborhood near a community college, where the whole house would lease around 1,650 but three rooms at 725 each brings in 2,175, which is the entire case for running it as a co-living property. The harder decision is usually utilities. Say fourteen months of bills show electric and gas together averaging 268 a month, with a wide range across seasons, water and sewer running a flat-ish 95, and internet around 70. All in, that's roughly 433 a month, or 144 per room. Three structures are worth weighing against each other. Folding utilities fully into rent produces a higher headline number that can look expensive next to lower-cost rooms nearby. Charging base rent plus a separate utility fee sized to the real average keeps the headline competitive but shifts seasonal overage risk onto the tenants or invites disputes. A flat fee set below the true average, absorbing the difference as a cost of keeping rooms full, is the option operators often drift toward, and it deserves scrutiny rather than instinct, since it can quietly erode a year's cash flow by four figures if the gap between the flat fee and actual usage is large. Modeling all three against a full seasonal range, not just the average month, is the way to make this decision with eyes open before an offer goes in.
