However, in hot real estate markets with 10% plus annual appreciation rates, the impact can be significant.

What options do I have to help my tenants to have some type or relief from the upcoming hot temperatures?

We are planning to add a hot tub once we get a few bookings.

For example, cleaning a 2br condo will be much less expensive than a 5br home with a pool and hot tub. 

They all play a role in determining whether its a hot/cold/warm lead.

Growing up in a household with 6 siblings and parents working hard to survive living in California I became very observant of what others were doing to make money.

Heating, air conditioning, hot tubs, major appliance failure, septic issues, etc.  

I'm not saying that would happen necessarily, but just be aware.If the space runs cold in the winter or hot in the summer, you can have a bit of a problem with heating/cooling along with complaints.

yes super hot!

Heck you could even paint their side hot pink (I wouldn't suggest that).
