House bought but moving in later - experiences?

Hello everyone,

I have a question again and hope for some experienced input from a few members.
The following scenario is currently with us:

We are very interested in a house and would like to buy it. Loan inquiries have been sent out and we are currently comparing.
The house in question is supposed to be sold this year, but will only be available in the summer. The reasons for this were given by the seller and are understandable.
Since we are currently renting, however, we want to avoid double burdens in the form of rent and loan installments. Does anyone have experience or ideas on how to deal with this?

There is already the following idea, but I don't know if it makes sense or is feasible – as I said, experience is lacking.
The house purchase will be completed this year and from 01.01.2016 the former owners become tenants and pay me the amount of the loan + additional costs. That way, the loan can already start to be paid off (interest-free provision period > 6 months usually costs extra), but there is no double burden.

Good idea? Not a good idea? Can it be done differently/better? If yes, how?

Thank you very much for your advice.

Is completely customary. However, I would strike out the tenancy and name an amount, for example 6 times the interest on the loan (of course without repayment), which the sellers receive less when buying the house. Consumption of additional costs is monthly - all of this is recorded in the notarized contract. The notary will already have these components saved for the contract.

Buy now, but schedule the handover date + the payment for the summer and have it recorded by the notary. After the summer, set a penalty rent equal to the local rent if they have not vacated the house. That way you have no costs. If the seller needs the money immediately, lower the price.

The seller is concerned about planning security, hence the sale still this year. The house will only be available as stated in August or September. However, since the financing must also be arranged within this year and the interest-free period on standby loans usually lasts only 6 months, I currently see no other option to avoid double financial burden.

: Why only the interest? Then we would still have the additional burden from the repayment.

No, repayment should be considered independently and is only advantageous for you. After all, you are paying into your own pocket. The loan interest is your burden. Or do you want to impose 19% repayment on the sellers monthly, of course

There are banks that are "bereitstellungszinsfrei" for 12 months, it’s all a matter of negotiation.
