Recent articles I have read online say that studies have been done and have shown much higher amounts of radiation if you live .3 miles away from a cell tower, which this place is located within that radius.

We plan to replace with tankless water heaters and in-unit high-velocity small duct central heat and air (using electric baseboard for the garden unit heat), and also remove all the radiators from the building.With the furnace and water heater removed, we would like to knock down the walls dividing the current furnace room, and make one larger rear, which is the bulk of the remodeling work to be done. don't not currently have drawings or architectural plans.

Their strategy is to pinpoint good areas then radiate outwards and target solid, affordable properties as close to them as possible.

I've used Hammertone paints on old rusty baseboard units to good effect, the copper looks particularly nice.A friend has spent considerable effort getting steam radiator covers because the condo sponsor's contractors pitched the 80 year old originals.

Get the radiator/oil type, not the fire-hazard exposed-coil type.

@Jim Adrian I guess it just depends on which internet site you choose as I found a few that definitely push vinyl over aluminum.That second link even says Vinyl comes with UV stabilizers that work to keep sunlight from breaking down materialhttps://www.stanekwindows.com/vinyl-vs-aluminum-wi...I just see info that aluminum frames are prone to corrosion, cost more, and act like radiators. 

The house has radiator heating, and this of course would not be split amongst the two units.

Looking into my first deal and stalling a little after walking through property side by side twinasking 70,000 for both sides; 2400 total square feet, 1200 each sideone side is almost completely gutted with new electrical work only.needs Hvac, sheet rock, full bath, kitchen, floors, half windows needed to be replaced and reframedother side is "livable" and "passed inspection" think feces, stains and smellsneeds new floor, full bath, kitchen, floors, half windows need to be replaced and reframed.has electrical, radiator heatmy question is I know this is a huge renovation but how do I get a ballpark?

When 80% of the properties have common laundry in the basement it is not something tenants are going to require.Same thing about radiators vs central HVAC - the cost is $15k a unit and it will not bump rents enough to justify the cost. 

Radiators?
