I've taken 2 top up's/separate split from my PPOR. Both have new account numbers so they separate loans. One top up I bought IP with same lender. Second top up I bought IP with another lender. Anyway are these top up's now crossed with the PPOR?
They are secured by the PPOR. The first IP may be x-coll with the PPOR, the top-ups won't be. Check your loan docs for the IP and it will tell you.
Having multiple loans against one property doesn't mean cross coll. Having multiple properties secured by the same loan(s) does. Cheers Jamie
