I removed the chimney entirely and installed a full HVAC system, making it the only house on the block with modern heating and cooling.

It will be a little trying for 6 units to use - they're slower because they do both washing & drying - but that would be way better than expecting tenants to drag wet laundry around.

In other news, water is wet.

They will try to run 2 kitchens and that can mean clogged drains in your wet bar kitchen.Be sure there is personal recourse when you need to sue them for $40k in repairs above the deposit.

They were never particularly nice, beach cabins on stilts with rattan furniture that usually had water stains from wet suits.  

I work with a ton out of state investors that are just getting their feet wet, so I'd be happy to connect and see how I can help you as you're coming into the game!

Sounds like a cool opportunity and it also sounds like a lot of folks have some good ideas/approaches.

Gullies, trees, brush, wet ground, etc.  

While I use it primarily for noise concerns (it alerts me for sustained +80 decibels), it's also handy for cigarette smoke and tracking temperatures (in addition to our Ecobee thermostat)- sensors on all exterior doors and possibly windows (which you might have via smart locks for the doors)- exterior camsA recent guest for reasons only known to them set the thermostat to cool and 60F in the winter (where it's currently a balmy 11F). 

Cool wish you the best and post about your project as you go through the different stages I am sure the audience here would really appreciate it from your POV
