The front door wooden stone built or prefab house
Sorry, I have to laugh...
I can already hear you singing at the construction site: "Wood on stone, wood on stone, my little house will soon be finished"
Let me guess, it was something like this: Since you live next door and needed a garage, you built one in EL for €25,000. When you finished, you clapped your hands and said to yourself: "It turned out great, and it wasn’t that hard." And that night you dreamed the house next to the garage.
So now you should rub your eyes and wake up. The value of the plot, says your municipality – standard land value. The bank probably won’t credit more than that. At best, the value of the garage will be added. That is then your equity. That will help you get a slightly better interest rate.
For a household of 5 people and an income of a little over €3000, any bank with even a bit of honesty will still not lend you more than €180,000 with both eyes open. Unfortunately, that is not enough for a house, at least not if it is supposed to be move-in ready.
Read through the planning and cost topics here. That will give you a sense of it.
