It is 3 bed 1 bath with central air.

I purchased this home while stationed at the Air Force Base. 

Hi, im from Buenos Aires, Argentina and im looking to buy a rental property in Columbus, Ohio.

If you need to be close to your property, consider being close to an airport instead. 

Tear out the carpet and remove the poop and air out the unit.  

Or are there actually two different heating systems in the building (radiant heat and forced air)? 

If the property comes in at the low end of your estimate of value, you're already at 76% without considering carrying costs or closing costs.If you're buying in Baltimore, your comps better be air tight. 

He described the property and how close it was to the base, Marine Corps Air Station Cherry Point.

We cover Vero Beach, Fort Pierce, Port St Lucie, Jensen, and Stuart.

When I was in the Navy they would give us a list of bad places/areas to avoid when we pulled into a port on the submarine.That's were we all went including the people who told us not to go there.
