Rental Income

I am looking to buy the 3 bedroom apartment that I am currently living in. The other 2 rooms are already rented and the current landlord has contract in place. There is also a garage box that is rented. 

So I will be taking over these contracts. The combined income from these are 1550CHF per month. If I can use this income to top up my salary then I can will be within the required monthly income bracket. I have the 20% deposit in savings that is required.

My question for the forum:

I wish to inquire if you know any banking facilities that will take the garage and rooms rental income to support my monthly income?

I have asked UBS, Postfinance, Raffeisen, Migrosbank, Credit Suisse and CLER.

They have all said that rooms rental cannot be accepted as a form of guaranteed income. So I would not be accepted for the mortgage approval.

Thank you in advance for your help.

If several banks have rejected it, it could be difficult.

You could also ask mortgage brokers, as they have connections to several banks. Some Swiss mortgage brokers: Hypoteq, Hypohaus, Moneypark, Hypotheke and others.
