There's not much ventilation so I thought about adding vent fans or windows to the hallways and stairwells as they all have at least 1 exterior wall.A cheaper and easier solution I thought might be a commercial grade air purifier in each hallway and some plug in air fresheners.Every room has 2 vent fans, a window, and a through the wall air conditioner so the rooms have good ventilation but the hallways can get stagnant, especially in the summer when it is hot(no a/c in the hallways and stairwells).Any suggestions that don't cost a fortune?

#industrialAt this point, I am looking for some basic 40,000 feet in the air view information.  

Looking to see if anyone does Air BNB and does not own the property?

I assume vacation rentals/air bubbles.

All my expected numbers (cashflow wise) are in the air, now on all the deals that I see.

Look, up in the air, it’s Austin’s super housing market — and it will remain relatively sky-high for years to come, experts agree.More than a dozen economic and residential real estate experts interviewed believe this is not a bubble that’s in danger of bursting.

due to the money that I haven't been making I cant afford to get move money up after paying monthly expenses. there is no heating or air. or hot water. have to use a bucket under the kitchen sink and the sockets have caught on fire twice.. they charge me for insurance but its to protect the interest of the landlord. this is PMI property management...

I am an agent that specializes in buy-and-hold rentals but I am interested in buying a vacation rental for short term tenants or air B&B rentals.

You will need air tight business systems to mitigate some of this. 

How about mini split air conditioners, vs their own window units?
