Hi there
I was asked a few days ago about buying land as a expat in the Ukraine. In short as it stands you are not able to buy just land. But you can buy property with land attached. You often find in the villages houses for sale with land, these can make a good opportunity, to invest.
Houses in villages often are much much cheaper than in the city's and often come with a little bit of land, sometime you find a gold mine that has a house and a lot of land. This land can in most cases be divided, and sold off to neighbours etc. Also owning your own property gives you a place to register too and this is a must if you wish get residency in the Ukraine.
If and when you get land , you must go too the local government office and file the land as change of use. Most land will be down as agricultural so until its change, you can only grow things on it.
Feel free to ask any question on this subject , you never know i may now the answer.
