On a mortgage application, what's the logic - and is there any evidence for it - regarding longer length of service being 'better' for an applicant?
I can understand if you've only been in the job a week, sure.
But having been at a company for 5 years just says that the company was hiring 5 years ago. "Only" 3-6 months service means that the company was hiring quite recently and so is in a growth phase, or at least not a recruitment freeze? Which would seem to be a good thing statistically for outlook of that job.
Edit: this isn't about a specific lender's policy, but the general recommendation about that.
