@Rachel Luoto cell towers potentially have issues with radiation that may scare some people away

If you exhibit an understanding of the vernacular and can talk in extent about real estate and the numbers, you present yourself as someone who know what they are doing, and oftentimes that is just what some people need.I wish you the best of luck and I hope that your enthusiasm will radiate and will rub off on your husband.

Yes, radiation causes cancer, but nobody really knows exactly how much exposure is too much, so they set the "actionable limits" for radon pretty low.  

Many of the units are now missing the window AC units that were once in 2 rooms per unit, and several of the radiators (approximately 5 out of the 24) are gone too. 

The heating system in the building is single pipe steam radiators.

I also had a steam boiler with old radiators and pipes and those caused major issues. 

My concern is with the baseboard radiators.

I just offered on a duplex that has one boiler and only has a radiator in one bedroom in each unit (units are 1st floor and 2nd floor).

@Michelle WilliamsWe started out in the basement of this property and talked about the typical things to look for when walking through:Electrical work, foundation leaks or cracks, piping, asbestos, gas meters, structural integrity (support columns, rafters) and heating (forced air water heater vs radiator boiler)The basement of this particular property (according to one of the tenants) was actually a beauty salon about 20 years ago, so there was still a toilet in place on one side of the room, as well as an additional entrance.Aaron mentioned that today gas companies prefer to have the meters on the outside of the unit for access, and since these were on the inside Peoples Gas would do the necessary work to route them outside the unit.We traversed through the back entrance to the top floor and walked through, noting the floors, kitchen area, bedrooms and closets, bathroom and living/dining areas.  

Radiators can leak or crack, and they can be hard to find if you want to match what is there, and very heavy to deal with if more than a few feet in length.
