I was hoping to air bnb out the duplex until I can move in.

E.g. opens the window, closes the bedroom door so air isn't circulating, etc? 

We spent evenings and weekends cleaning them because we couldn't get reliable cleaners.

It would be very unusual for a condensation line blockage to cause problems this time of year here in Birmingham because it's been cold here lately...so nobody has their air on...and the unit doesn't produce condensation in heat mode.For a future preventative measure though, I would recommend you have an HVAC company install a pan underneath the unit in the attic (if there's not one there already) and attached to that pan, ask them to install a "float kill switch".

@Erik Kuhi, I just use the AIR BnB and VRBO apps on my phone. 

Purchase price: $220,000 Cash invested: $60,000 This property is a Pocono Mountains vacation home and is listed on air bnb.

Need recommendation for realtor, and then eventually will need helps from handyman/electrician/plumber, cleaner crew if we're going forward with STR. specific questions I have in mind at this point:1.

rent by room on air bnb, if so, how is it around that area?

Always air more on the conservative side here.5.
