I’m not super keen on having long-term tenants in a single-family home in California, but I’m open to advice on that.The house is in decent shape but could use new flooring, a paint job, and potentially heating and/or central AC, as well as blocking/taking out the existing fireplaces (don't love the idea of fireplaces in a rental). 

This year we had a heat pump cleaning, testing refrigerant charge (didn't need any added) and a capacitor replacement, bill was $157.05, factor I consider are the age of the existing unit, if it needed a charge, potential leak, cost of refrigerant (over the years there have been many varients of the type of refrigerant). 

Others may have had a good experience but we would have been better off lighting our money on fire to heat out our home.

At the beginning of every winter season, I send a message to the tenants with the account information and let them know to call the gas company if the heat goes out.  

Wow this thread has gotten heated. 

That renovation included everything inside the exterior studs (all-new heating, electric, plumbing) and exterior siding.

Since I personally always get the most out of conferences when I have dedicated time after to decompress, digest, and implement what I've learned, I booked a private beachfront villa with some friends for a few days immediately following BPCON (checking in the afternoon of Wednesday the 9th, checking out the morning of the 12th) just a few miles up the beach from the Moon Palace Resort, and we have a couple of beds still available so I wanted to extend the invite to folks here.A couple photos of the villa are below, and some of my favorite features of this place include:- Direct beach access off the back porch- Private heated infinity pool- Private furnished terrace- Private resort access- Wifi- Indoor jacuzzis- Private kitchen- Air conditioningShoot me a DM if you're interested!

I'm not sure if the OP is talking just about water, heat, electric etc.

Similar to Realtor.com the leading real estate company Zillow announced it will disclose climate risk features such as: flood, fire, wind, heat and air quality risks.

Very dependent on each home's usage profile (as you mentioned) along with heating/cooling equipment type, utility rates and and solar net metering schemas.
