they are the most popular type of mortgage used to buy buildings and land for business purposes
they are offered to start-ups, small to medium busineses and large businesses,
the lender holds the legal rights over the business property/land until the loan is fully paid.
How do they take advantage of people? When you sign the papers, you are saying that you understand and agree to the terms and you agree to pay a certain amount of money a month for the privilege of living in "your" house until it's paid off.
Don't pay, they take your house. Fair enough
