As Serbian/Dutch with wife from Croatia - I can definitely say that prices didn't rise only in Croatia.
Basically same % rise in (non-EU) Serbia, and The Netherlands.
Possibly elsewhere too - but NL/CRO/SRB is where were have family and spend enough time to really know.
For example - personal opinion disclaimer - if Spain had better tax scheme for small business (not really sure on the nomad status there, but I am more interested in long term) I would probably move because the coastal cities in Spain are much better for similar prices, I would rather live in Valencia than Split/Rijeka/Zadar/Dubrovnik/Pula.
We got lucky to move to NL and then buy house just around the time when post 2008 crisis was at the lowest point. Some houses are only 2x more expensive than back then.
Meanwhile apartments in Belgrade Serbia are now similar to price of apartments in Amsterdam/Amstelveen/etc from 10-15 years ago.
From what I've heard from friends and family - more of the same across France, Germany ...etc.
