I don't think that is how it works. In the ad the Kaltmiete is €1900, which is simply the rent without utilities. It does not mean that a. you are eligible to buy that property b. the buy-to-rent price will be the same.
And even if it was, the legal costs alone add up to a few tens of thousands of EUR for a property like this (eg. if the property is worth €500k, you are looking at at least in the order of €50k of legal costs and taxes...). But I don't know of any bank that would lend you 100% of the price of the property you want to buy, if you do please introduce me to them...
If it really was so easy, everyone would be buying these properties. But the upfront costs are simply prohibitive.
Every lender (Wüstenrot, Interhyp and Sparkasse) were ok with 100% lending as long as I was able to bring in my own 10% for legal/buying procedure. Of course it was during cheap money phase. Now it might be different. I also wouldn’t buy a house from last century anymore with current insane gas and electricity prices. And this makes things complicated since new buildings are very rare.
