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

With that much more money in circulation, when do we get significant inflation?

Use a sump pump to circulate the water. 

This exacerbates the problem mentioned before regarding individual unit control, as well as raises an issue of where the return air is ducted from (i.e. if there is a smoker or otherwise unpleasant smell, that will get circulated through all units).1.

For those in the business, how much does it cost to replace a circulator pump?

I'm going to consider brrrr a little more as it's something I'd like to add to my "tool box" to keep money circulating. 

Air circulation, and spraying and wiping with bleach will help, and done regularly, may keep the infestation at bay.

I’ve only seen a couple listings on Craigslist for multi families in the area that are FSBO but none that cash flow well considering they require almost total renovation.I know there must be a decent amount of off market deals circulating in the area as it is a hot market.

Are there any petitions circulating in support of landlord rights that I can sign and help circulate? 

Rainy winter so can’t open windows, but have had air circulating.
