There is not a particular interest rate discount tied to this factor- once negotiated, it becomes a part of agreement. And negotiating this requirement beforehad would to submit another mortgage application. I don't think any banks here allow you just to have a mortgage agreement without an account at them- they deduct the monthly payment automatically. It might be possible with other types of loans, but I don't think it can be done with mortgages.
