Answer:
Hello! :)
The answer to your question is.....
Blended mortgage payments are mostly about repaying loans.The part blended means combined. You still might be confused, let me say it more clearly.
Ok so...pretend that you took out a new loan. The loan you just taked out will be added to the loan amount you already had, with the amount of mortgages being blended/combined.
Hope this helps! :)
