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? 

@Shia Rubin great advice and points to ask @James CarlsonI live in Boca and spoke with the city who basically said what you know--it's not allowed.People do it here but at the risk of being found out and fined.I didn't ask the more specific questions @James Carlson did, so missed those details.You may want to check out Delray Beach-the town next to Boca- where I know several folks Air B n B ing.

If that's up on the air it's too early to decided as you're going to be faced with potentially having to pay that LT tax gains and scrambling to find a replacement property. 

Haven't used AO Smith in several years because they used to have alot of problems with the air inlet vents getting clogged.

#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.
