When I started to prepare to buy rentals for a long term real estate portfolio for my retirement, I checked the weather maps first.

At least the weather will be a little cooler in a few months when you move.

It's water resistant and tough. 

I just dropped 15k on a bathroom remodel and replacing all weathered wood windows with new vinyl double pain windows on a duplex building.

I think as you educate yourself and perhaps the reason you are on BP is to learn from experts, smart use of leverage and ensuring solid cash flow to weather downturns is how big time wealth is created and gets you there much faster, nor paying all cash.

Like others have posted in this thread, you need to have reserves and recognize that things will go wrong and you have to be able to weather the storm. 

If it does NOT have any debt on a income producing property will help you weather the storm.

I see nothing that indicates that the San Diego market going forward will be different than history indicates (but history does show RE cycles so you need to know you can weather a down cycle). 

And then of course, there are a few folks who absolutely need to sell now - but you can find those in any weather.

In Austin, we have areas where there is alot of clay which is expands and contracts depending upon the weather (rain or sun mostly) as weird as that sounds.
