Yes. Secured debt consolidation loan (as well as unsecured debt consolidation loans) exist. If you have a secured debt consolidation loan, they secure it against an asset like your property. This added security lowers the risk to the lender and this means a secured loan may come with lower interest rates than an unsecured personal loan, giving you lower monthly payments.
Despite all of this, a secure debt consolidation loan is not without a certain element of risk. Think carefully before securing other debts against your home. Your home may be subject to repossession if you do not keep up repayments on a mortgage. Not to mention any other debt secured on it.
