Look at the consumption.

If they decide to split utilities, it's actually a win-win; they can reduce their consumption and save money and it's a greater net savings of $250/$150 a month for me.

One should ratchet their debt consumption down over the course of their investing career, but most people could not even participate in real estate investing absent debt products.

If the bill is that high, they should have noticed the massive increase in water consumption and contacted you. 

We've reduced the energy consumption of properties by as much as 70% with no more than a 10-12% increase to our renovation costs.Of course "Green" is more about marketing than energy efficiency :-)

The homeowner is responsible for everything downstream of the meter to the point of consumption.

Very efficient.Chances are the older system has substantial duct loss and should be tested.Mini splits have their place but cold air is heavier and drops so the bottom floor doesn't make sense.Electric motors do not raise in load consumption as they age, it's the mechanical work done that raises load, typically deferred maintenance on belts, shives and pulleys.I'd disqualify HVAC companies by asking; Are you proficient in the new Manual J,S & D standards (that will be required in the industry moving forward)These companies will understand laminar flow, stratification and static airflow imbalances that have a great effect on efficiency, operation and longevity of a conditioning system.Get 3 estimates, compare scope & make sure its permitted.

And without doubt, the pandemic injected trillions into the economy that have been slow to burn off.So let’s look at 3 charts: Personal Savings Rate as a percentage of disposable personal income, Credit Card use, and Consumption as a percentage of GDP.Disposable Personal Income is after all taxes are paid.

It seems that beyond submetering, we as Philly landlords have no recourse in regard to this issue, no matter if it's due to consistent tenant overuse or the city making wild guesses about water consumption.

Im not saying consume for the sake of consumption.
