Zinspoker - Long term or short term?

Take advantage of your income. Unprofitable to be annoyed forever if you don't do it.

Would you prefer a long-term financing at a relatively high interest rate beyond 3 percent in this situation, or rather the shorter financing with the prospect of possibly being able to pay off a large part of the remaining debt after 10-12 years (investments and sale of the inherited property)?

To come back to the original question here once again.

We decided on the shorter option (despite the low interest rates..) and if I were in your situation, I would do the same. You have the very best conditions not to have to pay surcharges for even longer fixed interest periods.

worst case (extreme inflation of energy and food prices) 2500 €.

My personal opinion on this is that everyone can best assess their own income and expenses. You can explain to some here how you might not go on vacation for a year, or don’t buy the newest technical device, or have other saving potentials (because one previously consumed indiscriminately, for example) and still there is always someone who finds something to complain about, in your case the underestimated renovation costs.. Or the too low costs for windows, despite submission of quotes. Or questioning the income because one expects income jumps for the coming or following year (which are plausibly explained)...

Or the subject of children etc. pp..

Electricity costs almost nothing because of the photovoltaic system, wood costs nothing either.

I hope you don't also have in mind that the solar system pays for itself? Otherwise, you're flattering the calculation twice :) and even then only if heating during the sunshine hours in winter is enough for you.

I think he will use the oil heating.
