Help us make our dream real

I've had a dream - to live in a nice house with a pleasant yard with some pets living together with my family. Since I was born, I've been living in an apartment. My only touch to the life in a house was when I was visiting my grandmother. It was so great there... My mom had the dream for a house too... Unfortunately, she died by cancer before she was able to buy one, she hadn't never got the money for that. Now I have the feeling that I would somehow satisfy her making her dream real if I'd got a house... My partner - my girlfriend with who I live, also shares my dream for a house. Unfortunately, we cannot afford it...
