Home calculation - realistic?

That could be true... the reason why we still want to wait 2 more years is to save up more equity. We should manage about 20,000/year, but that is almost offset by the possibly increased costs.

There are five good reasons not to wait: 1. Money is currently very cheap. The extra equity will not improve the interest rate accordingly. 2. Construction costs are steadily rising. 3. Building regulations are making construction increasingly expensive. 4. You pay rent for a shorter time (if you are a tenant). 5. You enjoy your own house sooner. There are of course also good reasons to wait, which I’ll simply leave out here.

Sounds absolutely understandable, but at the moment we are only paying 550 euros rent and have not really looked into houses at all. We want to take our time and compare carefully. It’s quite possible that we will also sign a contract in 2019 if we are sure then.

Hey, I'm just tempting like the evil snake Kaa...

I would also start building. It will take a while anyway until moving in.

Until you have found the right building partner, finished the planning, and the building permit is granted, a lot of time will pass. Then the construction phase, which takes a bit longer anyway because of the EL, so moving in will probably be in 2021.

Building won't get any cheaper either.

I'm just not sure whether a prefabricated timber frame house is the right choice for you regarding the EL. Many still exclude painting and flooring (some also offer turnkey without painting and flooring. There is at least one in Estenfeld among the show homes that states turnkey excludes painting and flooring). For other works, the cuts are often meager and disproportionate.

Am I the only one here who just noticed that the OP hasn't written anything about equity, household income, or parental leave? With a construction sum estimated at 550k€, it is rather questionable to suggest starting building now when basically nothing is known. Given the circumstances, I basically agree with foregoing saving in the current situation, but the income also has to fit, because an offer proposal is by no means a loan agreement and if the planning is far from complete, one should not sign any financing.

With a construction sum of an estimated €550k, it’s rather questionable to suggest starting to build now when actually nothing is known.

Given the conditions, I fundamentally agree in the current situation to forgo saving up, but the income has to match as well, since a proposal offer is by no means a submitted loan contract and if the planning is nowhere near ready, one should not sign any financing.

I can gladly provide some key data and I am, of course, happy about feedback:

Financing requirement is between 450,000 and 480,000.

Household income without 13th salary and Christmas bonus is €4,800.

There is a desire to have children, although we both want/have to work full-time again relatively soon.

During parental leave, we would then have “only” about €3,900, which should still be sufficient.

As a monthly rate, we are imagining €1,500.
