Are they retro fitted for earth quakes?

I’ll add:1- regarding earthquake risk, I’ve given that a lot of thought too.

In case of real estate, you are one big earthquake (I'm from California :-D ), or hurricane, or flooding away from being wiped out. 

You have to use the whole population not a subset in your calculations.China population 1,396,164,036 Covid 19 cases 80,754 = .00578% deaths in China attributed to Covid 19 cases 3,136 = .00022%https://www.livepopulation.com...I'd be a lot more worried about a 'quake in SeattleWashington’s 30-year earthquake drill for the ‘Big One’: Order studies.

With tile roofs, stucco siding, no storms, freezing, or “real” earthquakes, I average about $250-$300/mo in repairs and cap-ex combined.

There's also resistance (and for good reason) from environmentalists and those who see what overdevelopment does in the face of mother nature as california keeps expanding into wildfire and earthquake territory.

@Jay Maranan just an FYI, my primary property is 5 stories, of which almost all the carpet in the units has been removed(90%)...the original flooring is beautiful oak, that was original installed over 90 years ago, however, the units that just have the carpet torn up, sanded and stained the original flooring are much louder that the units, that I lay down subfloor, underlayment foam, and new floors over the original solid wood(I know it is sinful to purists, to not refinish the original wood, but it cost more, takes longer, is louder, and less isolation of bugs, and leaves some of the earthquake retrofit hardware exposed, if I do that) ....BUT, with carpet and/or wood floors it will be noisey...that's why the 5th floor are the "PentHouse" units, since no upstairs neighbors, even though identical layout to the below units, they can demand a bit of premium, especially if your new tenant has lived in apartments before.

I would have guessed it was a massive earthquake that might make that stuff useful living here, but if it's a virus, so be it.

For Miami you're looking at Allapattah, Little Haiti, Little Havana, North Miami, Miami Gardens, Liberty City and the general north eastern parts of the city.

This question is literally asked weekly.Start with no state income tax, cheap insurance, low property taxes, tile roofs, stucco siding, and low maintenance yards, landlord friendly and no snow/hurricanes/hail/major earthquakes, that should narrow it down for you.
