In short, the answer is no. Just as long as you have enough free equity in your home you should have no problem obtaining a secured loan. 'Free equity' is a term used to refer to the amount of property that you actually own; if you have a mortgage then it will be the amount of your mortgage that you have already paid off.

Remember that the amount you will be permitted to borrow will correlate with the amount of free equity you have in your home; someone who owns their home outright will be able to borrow far more than another who only owns a small proportion of their property. You should also remember that it is possible to have more than one loan secured on the same home, just so long as you have enough free equity to support your borrowing.
