I have the opportunity to buy a plot of land worth €64,750 for €15,000.
First of all, the neutral note on the saying "Greed kills the brain." Nowadays, no one just gives anything away anymore. So check everything regarding this almost dubious opportunity. Building plot? Location? Access and development plan... is a house even possible there?
That would be €190,000 plus €15,000 for the plot. What other costs would I face?
€190,000 house (unchecked) €15,000 foundation slab €7,000 transport €20,000 technical upgrade according to KfW €10,000 electrics, painting, and floor coverings €12,000 kitchen €40,000 ancillary construction costs €10,000 necessary paving €5,000 planting Prices without guarantee and cheap DIY variants. Basically, your own needs dictate the house-building question, not the financial opportunity. If it were the latter, I would have a boat, a vacation home in Norway, and a Harley, without the necessary urge to actually use these awesome things.
