Interesting perspectives on a topic I've thought about a lot. I've heard of averaging & charging a flat fee, & using RUBS, but never met anyone who's actually done it successfully, seems theoretical, my prop manager has told me it gets messy when tenants don't pay & you decide whether or not to evict based upon that alone, & if it would hold up in court, etc. Also, if they don't pay, you'd likely be stuck paying to keep utilities on since account is in your name, would be difficult to collect back payments - a headache.
Here in MN its either landlord covers common utilities & increases rent, or sub-meter. I have 2 properties with common gas (furnace & water heater) which can be brutal in winter. Best thing I can come up with is to keep costs low (insulate, energy efficient appliances, landlord thermostats - tenants always mess with normal ones) and keep rents market until I it makes economic sense to sub-meter.
Appreciate other input.
