Convert boiler system to HVAC?

[David Fernandez]

Hi,

I am closing on a rowhome in Baltimore (Belair-Edison) that I am planning on renting out after the rehab is done. 

The main question is what to do with the heating and cooling system: 

    - Option 1: Service the current boiler (20 years old) = ~$200

    - Option 2: Upgrade to a new boiler = ~$2,500

    - Option 3: Duct the property and get a new HVAC system = ~$7,000

With a new HVAC, I may get a little extra rent every month (~$50), but I believe the biggest difference will be in resale value, if I ever want to sell the property. Since I am planning on holding this property, I am not sure whether it makes sense to upgrade or to keep the existing boiler.

Thanks for your input!
