So, the plan was, down the road, to remove the radiator style heaters on 2nd floor and put in electric baseboard and just let the furnace heat the downstairs unit. 

You need to show the tenant how to adjust each radiator per room.

tell him you want a boiler inspection and inspections of all the radiators or whatnot... and go along. 

The area is not fully transitioned by any means, but you can see more young professionals moving in, and as the city grows and the downtown continues to develop -- I could talk for awhile about the things going on down there -- we think value increases will radiate out from the core of those new developments.

This one is for those who fix and flip homes in Massachusetts or states that closely resemble MA in terms of temperature/climate.When fixing a property that has radiator heating and AC window units, do you guys always budget for a brad new HVAC system to be put in place?

Big radiators around the house so ideally I'd like to get rid of those, but if I do an upgrade, I'm looking at a hydro-air system that will probably cost me $25K at least.

One of our biggest costs is a full HVAC conversion - from radiator heating to forced air.  

actually this question deals more with radiators. 2 family home with 6 room apt over 4 room apt.The 6 room apt. does not have radiators in the kitchen or dining room.

I took out all the plaster, radiators then ran central heat/air.  

There's one boiler heating up water and providing heating through each unit's radiator.
