Thank you very much for the many responses; as I expected, the opinions are split in all directions.
For your information, I have a plan to get more points in future point systems (in other words, a higher chance of getting a property than last time). Additionally, an apartment with 3 rooms gives -1 point. Children (no matter how many) give +1.
What do you think of the following alternative:
Buying a used 3-room apartment (price would be around 200k-240k), which we could pay off in 3-5 years. This would also not affect the points system. Afterwards, living here "temporarily," having children, speculating on the next properties, and meanwhile sprucing up the apartment ourselves or beautifying it.
Theoretically, we would then have the option to rent out or sell the property if we find a plot.
Is the apartment’s financing as security sufficient for the bank, or will they probably not grant a loan without equity (excluding incidental construction costs)?
Regards
Simon
