We are about the same age as you, but already have a child in the household. It was very important to us not to have to make any major or even any financial compromises, as the risk of exceeding the amount quoted to us by various providers for a single-family home was too high. Therefore, I must answer your question "would you do that?" with no. We decided on a new-build terraced house; if the selected semi-detached house had still been available, we would have chosen that as well. For the price, we would not have found a nearly new existing property in our region either. We have a similar financing amount (including a large buffer for other doors, floor plan changes, different tiles, etc.). We finance with one salary, while the other full-time salary goes into special repayments, reserves, vacations, etc. However, I would not wait much longer, especially not until the family planning is completed, as this can still be delayed for many reasons.
