Borrowing and monthly costs
couldbuild estimates your new debt, interest during the build, and monthly costs during and after the work. Check these against your own budget and what your bank or broker tells you.
Low, middle, and high
The low and high figures come from the range you choose. They show what could happen if the numbers move. They are not best- or worst-case promises.
Risk labels
The comfortable, stretched, and high-risk labels are simple warnings based on the tightest monthly period. A bank will do its own checks and may reach a different answer.
