A real estate agent told me there was a spike in prices during the summer of over valuation and they are seeing it come down due to high interest rates and buyers hesitant to purchase at this point!  

Nothing major, I believe there has been a spike in crime because of covid-19 and people, mostly kids, have nothing to do.

My question is this - with rates spiking and deals in general grinding to a halt, how much additional leverage is there for buyers?

Jackson County Missouri tax assessments went out and some property owners saw huge increases - were talking CRAZY HUGE SPIKES for some. 

As rates rise, home prices will become more affordable to offset the spike.

House prices spiked in a big way in the UK, and the prices never really looked back.I think the same thing is happening in the US today with people begging, borrowing and stealing to get into the rental game.

A sudden spike in rates is highly unlikely - the more likely scenario is that rates increase slowly and over longer periods of time.  

Prices in Utah have spiked over the last two years as many head quarters have moved there, tax incentives and what not.

I will probably sell the shares next time there is a major spike in oil prices.Sorry wish I had better stock tips.

Generally it has (and always will have) absolute minimal appreciation but no major dips or spikes.
