I think there’s an issue with the A/C or maybe a blockage in the ducts because the a/c is running nonstop but won’t cool below 75 degrees (it’s set on 68 with the fan running). its been hard to regulate the temperature in the house for awhile but more intermittently.

For instance when it's REALLY HOT in Saudi Arabia and the middle east, or inundated with rain and snow in other parts of the world, coming to Orange County where winter temperatures are between 68-72 during the day, is a welcome change, and we don't have hurricanes! 

It's the reason why you don't see a ton more vacation rentals on those sites.There are limited exceptions in Vegas, such as condo-hotels, but your plan @Liam Weld would not fall into those.If you wanted to try it, I would look into the idea of doing it with a property that is technically in unincorporated Clark County, as that might possibly work.

My old company did that and created small micro-offices, I've seen it done for wood-workers, food production, welding, artspace, you name it.  

And I see some of the shakiness in Weld County with oil & gas being in the tank as it is.

Here in Denver the shared space idea has been used in many forms from micro offices to wood-working and welding.  

(two knobs... one to choose oven or broiler and the other to set temperature) I was charged $50 for the service visit and I sent it to the property manager to have the tenant pay.The next day the tenant calls and says the oven burned the top of their food and obviously the oven does not work correctly.

It monitors temperature, humidity, and electricity.

You could also have a separate agreement outlining house rules...I havent done this but it's something i'm considering.Here are a few issues that have come up while I've house hacked:- Tenants disagreeing about how clean the common areas should be, WHO is cleaning, and whether it's worth having a cleaning service (monthly)- the house's temperature- Some tenants leaving things out in the common areas and other tenants getting annoyed at it.Every situation is going to be different, but if you've ever lived with roommates...it's similar to that, except you're not paying rent! 

Answers to the other questions depend on a lot of factors, and the temperature of the market as we head into presumably tough times.
