Ramat Hasharon is less expensive than TA, but kind of marginally so: https://www.numbeo.com/property-investment/compare_cities.js... (Cf. with Ramat Gan, for instance: https://www.numbeo.com/property-investment/compare_cities.js...)

Also people who live there identify it as a “plush suburb” themselves.

I appreciated the data and response. Those prices are entirely off though. Here is a local and more accurate source it's common for Israelis to check (other ones are yad2.co.il , homeless.co.il, newspaper sites and surprisingly a facebook group called "Apartments between friends"):

It’s hard to compare apples to apples here: there is, for instance, a 5-bedroom apt in North TA for 4850k and a slightly bigger on on RSh is 4500k, 7% difference. Other pairs with higher percentage difference can be found, but it’s hard to extract the median or average.

But even if your estimate is correct and the difference in prices is “categorical”, the author of the piece could simply have had in mind the streets with private houses, which mostly cost north of 1.5-2 million USD. This is rather plush, I guess.

"Defense"/"Military" is not the same as "Security", and "Conscript" is not the same as "Official".
