I can see this as a possibility but I wonder if the spike in population, interest rates, and inflation would balance it all out a bit.

I am sure after Katrina the rates spiked

Are there still demand for Miami condo these days for the $500K range even with these major headwinds, not to mention the spike in mortgage rates?

You put your house up when rates dip - you win, you put it up when they spike - it cuts into your bottom line.

One additional reason I say that is be sure nurses aren't 100% of your MTR strategy - people got way too comfortable with the insane spike in travel nurses during Covid, but signs are pointing to that diminishing back to normal levels and now that MTRs are becoming so prevalent (especially targeting nurses) I expect an oversaturation of MTR supply for nurses in a lot of areas. 

I use those miles when prices spike and it makes sense to use miles for a trip.. or in the past I only used the miles for international business class which is a great use for those miles and paid for first class tickets on all business trips.. keep in mind you get a ton of perks with first class tickets no charge on luggage no change fee no cancel fee special check in line plus special line for TSA if your not TSA pre check which we always are anyway.. sometimes a discount to the lounges which again are critical for the frequent flyers enjoyment and experience. 

I was originally saving to buy a home and have a decent down payment that I'm still building but with the massive spike in the market down here since the beginning of Covid, buying the home we would want has slipped out of reach. 

So despite the crashes and spikes we've seen over the last 20 years, there is still a positive appreciation across the board. 

But what they won't tell you is the money being poured into it to revitalize it, since it is the closest area to UC that has not spiked in values as other neighboring areas.

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