I just closed on a house today and the furnace was/is  an old boiler/radiator system.  

, put $20k into it with about $10k of that work being optional-I had the boilers and radiators removed to install forced air heat and central A/C and made the switch to all-electric units.

Currently, we have boilers and radiators that we want to remove to create space in the basement for a future conversion into another dwelling unit.

Have a 1960s 30 unit single story motel where we are coming up on some end of life issues: the cast iron plumbing is disintegrating underneath bathrooms, radiators are starting to leak, electrical is in poor condition, and just today, discovered significant termite damage affecting multiple rooms.

She was given 3-6 months (this was 2005). 12 chemo's, 47 radiations and 1 mastectomy later, she was 'cancer free.'

I have a leaky radiator coming from the 2nd floor that it dripping through the ceiling.

I'm thinking a solenoid valve on a couple of the radiators tied into a local thermostat in each apartment would be ideal but I've never seen or heard of this.

The kitchen is a very small room - 10x9 - with the refrigerator and stove currently on the far wall with the clock - that door is the back entrance, the sink and one side cabinet on the left wall, and a relatively small walk-in pantry behind that radiator. 

Forced air was discussed as radiator heating was originally there however since now most days its preferred to have multiple units on their own heating this would make more sense.  

Some of the copper is gone on the first floor, but just easy stuff like the baseboard radiators, no walls were opened.Understanding that there are variables that can't always be foreseen, what is a good way for me to estimate rehab costs.
