My mountain home needed to be completely refurnished plus we added a hot tub (a must for cabin rental) which came with reinforcing the deck, so to get it Airbnb ready it was about $10,000. 

For example, as a "condo" unit owner, you may be responsible for maintaining the hot water heater or the carpet in your unit if it wears out or just needs to be replaced, but "not" responsible for insuring it if it burns up in a fire. 

., someone putting together a development who needed my property, the marginal area I invested in becoming “hot”, or buying a note at a huge discount expecting 15 years of payments and instead being paid in full in 3 months.  

On a sunny day, a building can get uncomfortable hot when it's 61 oustside.

Other details I have my own house meter and that runs one of the hot water heaters.

They only run when there is demand for hot-water and considerably more efficient.  

I'll take it as a $6000 lesson, but if you are hinting that it's someone not doing their job etc, and playing to the side of the "oh, poor tenants" I'm coming in hot.

Make sure hot water is where it is supposed to be, cold water the same.  

This is the second month this was true for the county overall and San Jose - but I do not believe this will continue beyond the hot period of the market.

Not good in a hot seller market.
