Ok -thx.
So given that the balance on the joint mortgage is 350k - my share being 175k and assuming my sibling agrees to reside in this residence and pay half rent to me. Furthermore, the joint residence is now worth say 200k, so we both have 75k neg. eq.
If I then apply for a seperate mortgage with my spouse (with a joint income of 90k) will the bank take into account my outstanding mortgage debt of 175k and/or my neg. eq. of 75k or neither in deciding what my loan limit is?
E.g., Would we be entitled only to 4x90 - 175 = 185K?
Thx.
