The mold issue is tenant caused likely due to air circulation.

Common areas can be enclosed or open space and are in turn driven by determining the density of NRA, parking requirements along with non-discretionary common areas (like internal or external circulation) and discretionary common areas such as a gym, laundry/vending machines and swimming pool/spa.

I was stationed in Italy till January since then the air circulated through out the house basically spreading bio almost everywhere.

Buy one big enough to shock treat the unit and make sure to have fans circulating the air and no one in the unit during those times.

Help em out already.Would've grabbed one of my several locksets I circulate around and had it swapped quicker than it took you to post the question, but that's just me.  

I know they have another offer on the table, and it seems this offer have been submitted after they circulated the info on our offer.

I'll elaborate a littleExamples:  Natural gas hot airNatural gas hot waterOil hot waterOil hot airElectric baseboardElectric heat pumpPropane hot airPropane hot waterAs an overall, the first is what provides the actual heat, the second part is how it gets delivered around the house.Natural Gas Hot Air:  Generally there is a furnace that heats the air and has a blower, and then air ducts that deliver the hot air around the house.Natural Gas Hot Water:  Now it is a boiler that uses natural gas to heat the water (separate from the domestic hot water for your shower) and then circulating pumps that move the hot water through baseboard pipe units with "fins" for distributing the heat.Oil just uses that fuel (instead of natural gas) to either heat the air or the hot water. 

Will I always have a tenant will there be times I cannot find a tenant or should I hire a property management to help keep tenants circulating.

I know there is a ton of info circulating that may not all be true.
