Left to Live Flow

A Left to Live is a mortgage calculation before or in conjunction with applying for a loan. This calculation considers a series of parameters to evaluate if the requested loan amount is acceptable giving the expected life costs, helping to ensure that an applicant won't take a loan that becomes a strain on their personal finances.

A Left to Live request is sent with some information about the applicant, like income, family size, other accommodations, etc. The result is a rating that represents how well the requested loan fits with their given situation:

• if the returned rate is positive, then the applicant can take the requested loan amount
• on the other hand, a negative value presents a loan that is considered an excessive financial burden (in this case a new loan amount is proposed, considering the applicant's situation)

As of Q2 2022, cost of cars is included in the calculation, read more in the cost of cars section.
