I would guess that in those times you would see a spike in the electricity as the units struggle to heat.

When it showed up, the government made an estimated 1Q of safety net for common citizens assuming that Covid-19 spikes and then subsided like how it did in China or Korea.

Definitely a rough report - been really tough for mortgage rates these last couple of weeks, spiking really high again. 

If there is an unusual spike in water usage, it points to either a water leak, water waste or unauthorized occupants having moved in.

Also, interest rates are spiking hard making your pricing even harder to swallow for buyers.

I'm not trying to gouge people on rent because of the spike in demand and shortage of supply.

Apple, Google, Xerox, Fuji film, and Meta are all coming into the area. 5k people a month move to the area which has created a housing shortage, rent spikes, major appreciation (not just due to inflation) and you can still find single family homes for sale on the MLS in good condition for ~250k+ Tenant-landlord laws are landlord-friendly and taxes are low.

Conversely, if rates spiked I could have asked them to re-amortize the loan back out to 15 years and by stretching it out lower my payments and preserve my cash-flow.

@Michael Blair The spike in rental rates (and property values) over the last 10+ years has made investors LAZY!

Electric can also spike in the summer with A/C.
