House construction. Sell or rent out the condominium?

What contradicts me is that plots only cost 180,000 while apartments cost 380,000 and more. If I apply this to our area, the plots are at least 100,000 euros more expensive with similar apartment prices.

We are talking about a rural area, directly on the highway, about 60 km from Stuttgart. It is a new development area, directly from the municipality. Private building plots are sold for about 500+ €/m2 and are very rare. 20 km further, the m2 costs about 500€ (from the municipality). Prices for building plots have almost doubled in the last 10 years. New apartments are also rare. A new 4-room condominium (standard, no luxury) costs around 450k (+garage/underground parking space 20-25k).

You can always spin renting in a positive or negative light. In this case, I would spontaneously be on the side of renting, as the value suggests that it is a desirable location.

Actually, the only thing that helps is to properly plan the entire financial mix. So calculate both options through to the end with concrete numbers and make some estimates for the future, what happens if it goes well or poorly. Then you decide whether security (sale and lower loan) or a bit more opportunity and risk through renting (higher income vs. payment default, vacancy, etc.) lets you sleep peacefully.

Quite simple, right?

I would keep the apartment. It does not pose a risk. Lower the repayment so that the installment and reserves are covered by the cold rent. Possibly even hire a management company. The return may be low, but the tenants pay off your debts. In your situation, definitely keep the apartment!

The question for me is, do you want to live or turn every cent twice.

Assuming we keep the apartment and it pays for itself... We would have to take out about 600k (!!!) loan for the house. Interest + repayment about 4-5% = approx. 2300-2500€ monthly rate. Did I calculate that correctly off the top of my head? With a family income of about 5500€? Definitely not doable for us! Are there other solutions where the installment is max 1800€ and we do not have a residual debt of 300k after 20 years,

5,500 euros family income is only average and not really much. Many high earners already have that just with one person working. If a few thousand more per month were possible, then the situation would be much easier to manage. See my post above.
