Homeowners short-changed: Someone must be responsible

Buying a home is a reasonably complex process with all sorts of limits and regulations, but most of all someone who wants to buy a home must satisfy a lender they are capable of repaying any money borrowed. What a pity such rigid scrutiny does not apply right across the process.
Once those concerns are resolved, most of us are happy to sign on the line, maybe agreeing to make repayments over 30 years.
