This is not really true, Estonian market is experiencing a lot of problems at the moment. Many expats are leaving due to the insane inflation, creating a lot of vacancies on the rental market. Estonian promoters have been building sub-par stuff lately and there's a lot of stock on the market :
Estonian real estate developers increasingly cautious about projects
Real estate boom has been fueled by investment from foreigners (Russian, Finnish, Swedish mainly), and many have exited at︀ the top, so further growth is not warranted. As a side note, Tallinn is one︁ of the most badly managed capitals in the EU, with great amounts of dubious things︂ happening behind the curtains.
There is no zoning, or even planning, so depending on your︃ neighborhood, you may lack basic services. For instance, the neighborhood of Kalamaja is the densest︄ in Tallinn and has only one small supermarket, very few shops, restaurants or schools as︅ promoters only built housing there. Also, the city does not spread salt or even clears︆ the snow in winter (yes you read this right), so you'll need a car as︇ it's almost impossible to walk during the icy season.
As a last note about Tallinn,︈ bear in mind that because the promoters favored residential housing heavily, commercial space is hard︉ to come by and expensive. This leads to a great lack of office space and︊ high costs associated. Which is kind of strange for a country that likes to boast︋ about its startups.
In general, I'd suggest being cautious when reading stuff online about Estonia.︌ They are very good at storytelling, while the reality is much different.
Unless you have a pure holding︎ company, you'll need to pay yourself a salary of around 1500€ in order to be️ let in peace. Ah, and the CIT will be 22% next year. VAT is also 20% on everything, even medication or food. I wouldn't call Estonia a fiscal haven.
