Hello Schneemann86,
Two years ago, I was in a similar situation as you, looking for a property.
One thing upfront: You are approaching this correctly by first defining the financial framework and only then planning a house! Please don’t forget this during the further planning and especially during the construction phase.
Let’s summarize the situation for the end of 2012:
Equity:
Plot: €34,000
Additional equity: €40,000
Total equity: €74,000
With your presented income and cost calculation for the house, the financing – especially in the current low-interest phase – is manageable.
What worries me besides the car loan is the rough estimate for the house. I also paid significantly more for our house than the "catalog prices + fees" initially suggested.
Budget well and generously several tens of thousands of euros for "special requests," gardening work, garage, paving work, additional equipment requests.
I actually wanted to slightly "overfinance," but the calculation ended up exactly +/- 0...
So, let’s do the planning:
Monthly net income: €2,200
Realistically available for financing: €900 (car + living costs for 2 persons already deducted)
With €900 per month you could service a loan of approximately €240,000 (planned with 3.5% interest and 1% repayment)
In my eyes, however, that is a bit optimistic!
Better plan a little more conservatively. If you suddenly have to feed 3 people, the house of cards could possibly be on shaky legs.
In my view, financing around €180,000 under your conditions is not a particular problem!
The last catch still remains: interest rate development. In recent months, rates have been historically low. Currently, nominal interest rates of roughly 3, low % are available at almost all banks. That probably won’t be the case in a few months => financing will become more expensive! It could well be that you will have to finance at 4,X% or even more!
At 4.5% interest, 1% repayment, and a financing sum of €180,000, you would already have to spend €825 monthly. At more than 5% interest, €180,000 financing is then no longer feasible. This means for you: hope that interest rates stay low or act proactively and secure low rates in time either by building earlier or other measures (e.g., forward loan)
Best regards
