In fact only the coastal regions will suffer from sea levels rise per se. But no height will be sufficient to guarantee your safety, sadly, because this is not about literal Great Flood. This is about climate change and hundreds of millions of deperate displaced immigrants from places like Bangladesh who will make everywhere more chaotic than today. We're not prepared for the human part of the catastrophe.

I would bet that even under worst case scenarios + some black swan events 20 feet above sea level is still perfectly safe from sea level rise until 2100, but then you still have increased flooding from extreme rainfall events, draughts, heatwaves, ocean acidification, soil depletion, mass migration, and a number of other future problems that can wreak havok on people just about everywhere.

I don't think they're expecting much in the next decade or two, maybe a few inches?

I believe it's about 9m if the whole of Greenland (two major glaciers) melts. And another ~60m if the whole of Antarctica melts. Naturally this is unlikely to happen in our lifetime, but positive feedback loops are a fascinating subject.

For friends looking to buy coastal property on ~30 year loans I advise that they need to be able to sell those properties some decades out from a more general concern / awareness of the risk.

Don't live close to sea level anywhere that gets hurricanes (Sorry Houston, New Orleans, Tampa and Miami).

From TFA: "Globally, sea levels are rising by about 3mm a year."

That's really, really fast.

If it gets worse, it wont matter how many feet you are above sea level, except to not have your house submerged in water.

But the repercussions, like economic downturns, loss of friends and relatives, climate change created phenomena, food and water shortages, diseases on the raise, and so on, will affect everywhere...

If you’re more than like 150 feet above sea level it will never be an issue.

50cm by 2100. That's just under 20 inches for Imperialists.

This assumes a linear rise of 6mm/year.

So in the next 10 years sea level would rise by 6 cm (just over two inches; I understand there are twelve of those in a foot, so we're not talking "feet" until 102 years from now).

The bigger impact will likely be water stored on land -- e.g. snowpack. All of California's major rivers are fed by snowpack/glacial melt from the Sierras, if all that starts melting more, there will be flooding, and then in later years there will be much less water coming off the mountains (as it'll have already melted).
