The plot will be cheaper to purchase, but the house itself will not. If it is ever sold, however, it is a complete package that might not sell well.
This problem affects ALL those who have bought cheap plots (e.g., in the countryside). The low price is due to no one wanting to live there. So the sale is difficult even with a top location in the middle of nowhere. I always say that expensive plots have more advantages than disadvantages. The high purchase price offers something; otherwise, no one would buy it. A high purchase price basically guarantees resale (unless you really mess it up badly).
I would get the development plan for the property. It is possible that there are increased requirements for noise protection, then there will be an additional larger amount added.
Well, that only becomes an advantage when you want to sell - if you don't want to, then you don't have any advantage there.
And prime location is all well and good - but it's usually not quiet there.
all the years you live there you already have the advantage that you can live where everyone wants to live. (that's why the price is so high) and the sale of the property normally comes up eventually anyway, whether directly or indirectly. ultimately, your own property is the provision for the retirement home, so you don't have to be a burden on your children.
