I purchased Gutshaus Gnevkow in May 2011 at auction. It was in a terrible state, but given I couldn't drive at the time, the train station with its direct service to Berlin was highly attractive.
We spent most of the first year getting to grips with understanding the house and resolving immediate crises. The house required extensive work. There were no 90% grants for me - the best I received was for 33% of the cost of the roof, windows and stucco.
My tilers were Portuguese, my plasterers Polish, electricians German among others, and by some amazing fortune we were able to open in November 2018.
