How many mortgage loans do the banks allow???

To say the noteholder is the true owner of the property is simply a fallacy. Sure the noteholder has a security interest in the property but they do not own the property. The purchaser/homeowner has assumed all of the market risk by buying the house and as such is rewarded with any market appreciation or depreciation. The noteholder is simply a lender with a security interest which might be foreclosed upon should certain covenants be broken.
