Is this normal in renting in germany?

Hey, I'm an incoming master's student to university in munich and looking for an accommodation.

One of the landlord said I would have to sign the contract & send the deposit+rent to get contract signed by him.

Is this normal in germany (or munich) or does it seem like a scam?

I have done the video call and it looked legit to me, but I'm not sure cause there are lots of warnings about rental scams in germany.

It would be really greatful if someone have experience in living in germany could give me some advice.

Thank you!
