The HVAC has been completely revamped to provide central AC and heat throughout the home.

They require regular maintenance and sealing plus they can be sensitive to moisture and heat.

There is a sunroom attached that isn’t connected to central heat and air, but has a window unit.

Second is to put an ad on Facebook for free heating oil , It will go quickly . 

Landlord pays heat and water. 

Tenants running the heat and air conditioning at the same time.

(Which does sound like an owner expense, especially if you advertised a heated pool.) get a couple more quotes> I’m guessing it depends on if it’s like a septic inspection during a sale in MN.  

This was back in 2016/17 when areas of Columbus like Olde Towne East and the area around Children's Hospital, for example, were just starting to heat up.

The second reason is that pretty much every state has something called the implied warranty of habitability, which basically means there’s a minimum standard the home has to be kept in to be livable (i.e. working/safe electrical, plumbing, heating, etc).

Raising interest rates will be the way they slow down inflation and the heated up economy...
