We put in a new kitchen, bathroom, flooring, opened up the floor plan, new heating system and roof.

Copper supply and plastic drains are ideal.Make sure the heating works and is in good condition.

Maybe look into mini split systems , they are a heating and cooling unit for each room and dont require any ductwork.

Heat/AC systems - a lot of the heat around here is old radiators with a boiler in the basement, and a boiler can run you $10k if it's bad.

The graphs show that Zillow purchases on average are newer than Opendoor's and are larger in heated square footage.

It has central heat and air and a bathroom already rough plumbed.

It will cost you 5 to 6% of the selling price.It will result in many lookie loos wondering through your home, letting their kids destroy things, casing the house or stealing your things, etc.If its a vacant, furnished home it may become your agent's love nest.They can leave the air -heat or air conditioner- on in vacant houses. 

The system is a heat pump that was manufactured in 2006 but when I bought the house this March I did have it inspected, pulled and cleaned and it seemed to be fine.They haven't yet specified exactly what the problem is but I'm wondering if they're just preferring that I install the new system to make it easier for them, or to make their subcontractors happy with the work, or if it's really something not worth trying to fix.Anyone with experienced insights?

On that condo fee for 531 Main street, i believe it includes heat and hot water,  I think there is also so roof and facade work tied in there.
