Use a fan or a portable AC unit if the reason for the open windows is that it is too hot.Trying to chase all cracks and sealing off your unit in a 1980s building will be mission impossible.

Do not do showings, look at social media, or set up meetings during this time. 

Maybe handle FB ads or social media.

Other strategies that I would recommend: 1) Start with your network - Friends and family are low hanging fruit 2) Create a brand on social media and let everyone know that you do Co-Hosting 3) Network with investors - BIGGERPOCKETS and work together to find deals and then ultimately manage their property 4) Reach out to long term rental landlords to see if they would be interested in turning their LTR into a STR 5) Reach out to cleaners who are already working with Airbnb hosts who are self-managing who would benefit from someone Co-Hosting it

My property manager is asking copy of my social security card for new Section 8 tenant paper work. 

After that we were in the green and getting greener.....This should be  auto reply to every STR question about low occupancy on EVERY forum/social media.

Nowadays, social media is filled with scammers. 

As well as the entrenchment of social groups to ignore date and fact driven messaging, deciding there “tribe” and then with near cult-like fervor defending that groups messaging regardless of fact based information.

Learn the skills of social interaction.
