collateralized lending comes with smaller interest rates/financing cost because it's low risk for the lender
if you default - the lender keeps your collateral
haircuts and spread are set sufficiently high to cover liquidity, term and market risks
โ80% of lending in financial markets is collateral-based
financial institutions use government bonds as collateral for short-term loans
you're using immovable property as collateral for a generally longer term-loan
