Thank you in advance, I never thought about money twice before visiting this site!
Background Info: Germany. I am in my mid 20s. My long term boyfriend and I make around 100k a year together. He would be moving there together with me. If I continue my current carrer path and don't take too much time off for children, this sum will double in the next 10 years, but just assume it won't.
My dad has a barn with sheep and a nice big house. Too big for him now that he is retiring soon. He wants me to move back home in a couple of years to help him keep the house in good shape. The house is huge (more than 350 square meters of living space).
The relationship with my dad is excellent, we love and trust each other. One half of the house is in great shape. Everything has been renewed in the last 5 years. The other half needs quite a lot of work. It is still fine for living, but in the next 10 years I believe I need to invest 100-150k to keep it nice.
My dad and I were thinking of 3 possibilities for me to keep the house after his death.
Option 1: He sells me the house now for a symbolic low price.
Option 2: I buy the house for a more reasonable price, by paying a fixed amount each month until he dies.
Option 3: I inherit the house after his death.
My boyfriend and I were thinking of 2 possibilities on how to finance everything.
Option 1: My boyfriend pays me rent each month (we were thinking about 500€), and I pay for all expenses.
Option 2: We share all costs as good as possible, in the hope of staying together forever. ( We are planing to get married in 2021).
Security: I have around 50k in my bank, but I would also need to buy a car if I move there (countryside). My dad also has some real estate he could sell if everything goes down hill.
What are the best options in the long run? What kind of hidden costs do I have to expect in this type of scenario in Germany? Is this house to expensive to keep if I may become a single mom (60k a year)?
