At the moment, I would clearly recommend to you: Don’t do it!
I have noticed in recent years that even moving from one rental apartment to another is not exactly cheap (new wallpaper, new curtains, new lamps, new furniture, the move itself, etc.). Still, you should know when you are getting in over your head. And I think that is exactly what you are doing right now.
1. I still don’t believe that you will manage with €360,000 or that you will get the same value for it. For €1400 warm rent, I think you can get an apartment with 4 rooms and 120m². But then you also have a cellar room, laundry room, etc. included. You also don’t need space for house technology (heating, electricity, water, etc.). To have comparable space in a house, you quickly need 150m² or more. In our area, we paid €1100 warm rent for 4 rooms and 150m². We did not find a comparable house for €360,000. Even now, with significantly worse infrastructure, it is still more expensive price-wise. In the same residential area, we were between €450,000 and €550,000. And nothing was special there. Or around €300,000 but in need of renovation. Have this checked carefully with an expert. Anyone who says that a house built in 1975 without major renovation just needs new wallpaper is lying to you straight in the face.
2.) As you already rightly pointed out, the step from 2 rooms to a house is not a small one. Besides a lot of new furniture, there is quickly a kitchen involved that you don’t get for just €5000. Have you thought of garden tools? Lawn mower, wheelbarrow, hedge trimmer, snow shovel, etc. all cost a good amount of money.
3.) Make sure you understand how much you earn per year and how much money you want to borrow. That is already a significant ratio. Of course, you can plan to still have a residual debt after 30 years, but 50%? That’s possible if you don’t have children and then sell the property at retirement age to live somewhere else (Mallorca, assisted living, Maui Maui, etc.). If not, you would be leaving your children a substantial mortgage: €200,000 debt and a house in need of renovation. If your children don’t want the house, you basically have no choice but to sell because you won’t be able to pay the installments during retirement age, unless you actually expect very significant salary increases. Full financing (and you are already well beyond that) currently hardly goes below 2%. I think 2.3-2.5% is realistic. Let’s assume a monthly rate of €1300, then you need 40 years to pay off and pay 1.5% amortization. As you see, you pay significantly more interest than amortization (at least the first 10 years). Assuming the interest rate over the full 40 years, you pay €220,000 interest alone!!!! Are you still sure that is cheaper than paying rent? You can’t make the math look better for yourself. If we now take a rate comparable to €1400 rent, about €1100 (which is still optimistic since €300 ancillary costs are rather low), then it would take 55 years of repayment with €310,000 interest. It just doesn’t add up.
4.) You need reserves for a house. Even with a 40-year financing, you are then at about €1300 amortization + €300-500 ancillary costs (depending on the condition of the house) + about €150-200 reserves. That adds up to a total of €1750-2000. This still does not include a buffer.
5.) Your 110% financing will probably be very expensive. There are only a few banks interested in that at all. That means they will either not take you or only for a lot of pain money. At the beginning of our talks, we planned a 100% financing or slightly less. Even there, many banks dropped out, the interest rates were bad, and scenarios with private loans, etc. were calculated. The advantage for us was that we could demonstrate a significantly higher income than you, so we only had to worry about too little equity and the creditworthiness was very good. For you, not every bank will see it that way; conservative banks will even see the creditworthiness at risk. From my perspective, most will try to cover purchase incidental costs through private loans. These, however, have significantly higher interest rates (because there is no security) and currently range between 4-10%. For terms usually of 10 years, 10% of the loan means monthly payments of €400-500. Besides the interest on the main loan, there is almost nothing left for amortization so that after 10 years nearly 90% residual debt remains.
6.) Last but not least, a house also means a lot of work. That means especially when moving in, all the renovation work begins. Do you have the time, experience, and workforce for that? This brings point 2 back into play: a 2-room apartment is something different than a house!
As you see, it simply doesn’t fit. The idea that you “save the rent” is nice, but you then pay that monthly in interest. Everything the landlord is currently responsible for (damage to the house, repairs, upkeep) you have to take care of yourself.
If you absolutely must own property, you should try to hold out a little longer and save for the purchase incidental costs. Otherwise, you will pay for those twice through the high interest rates. Then I would possibly look for a condominium. Those are cheaper, also cheaper in ancillary costs, and usually can be resold quite reasonably in a good location if you want to move into your own house later anyway. Maintenance costs are usually lower because the big items are shared among all owners and thus renewal of the roof or heating is significantly cheaper.
Finally, a few calculation examples:
To get to a (still quite expensive) 100% financing, you need 13% equity when buying through a broker and 7% without a broker (broker: 5.95%, notary: 2%, property transfer tax: 5% (depending on the federal state)).
That results in...
... €400,000 loan - with broker: €51,800 - without broker: €28,000
... €300,000 loan - with broker: €38,850 - without broker: €21,000
... €200,000 loan - with broker: €25,900 - without broker: €14,000
Regarding the rate, I would advise you never to go below 2% amortization and to aim for 3% if possible. If we now assume a rate of €1100 at 2.3% interest (I don’t think you can do more), then that results in...
... 2% amortization: €310,000 loan amount with a 34-year term
... 3% amortization: €250,000 loan amount with a 25-year term
