I will angle the conversation as “I need to monitor the work to make sure I know any building issues that arise and so I’m on the same page with you about where we are up to”.Is there anything I’m missing, like I’d be in breach of some labour law etc.

Bigger Pockets has some great state forums and usually there are good locals that monitor those.

They'll provide the real insight, but here are some metrics I look at:-Population growth-Job growth with higher wages-Business friendly-Diverse economy-Strong occupancy rates-Acquisition price-to-rent ratio-Landlord friendly-Infrastructure development-Lifestyle amenities-EducationBest of luck!

I have family members in the aviation industry and they’re monitoring flight loads on certain routes and seeing the number of open seats increasing by the hour.

Trailers that occupied as a residential dwelling are considered permanent property by the IRS and are 27.5And land improvements or infrastructure driveways, landscape ect are shorter life and can potentially qualify for bonus depreciation. 

Mine can set door codes, message (or call) guests, schedule cleaners, adjust the thermostat, monitor my cameras, & call a plumber just as easily as a local PM can, for 1% of the costHire good cleaners, a solid handyman & befriend some helpful neighbors.

Not really, but can certainly keep watch/question/monitor how it is being managed, now that the lesson is learnt. 

Another reason they are interested in continuing is the property's multiple exit strategies and high appreciation potential because of planned infrastructure improvements.

Start by looking at what is the HOA's responsibility; if it's all infrastructure that leads to the unit then this is on them to fix. 

I just bought a property where the previous owner has purchased a termite baiting service that is monitored 3x a year for $275/year.
