Does someone being on maternity leave influence your decision when assessing applicant household income?

I am by no means discriminating against them for being on leave, but their household income only just met our minimum requirement for the property/expenses with full-time income from both parties. If one is on parental leave, they are technically no longer meeting that minimum. Do others take this into account when screening, or do you overlook since it is (supposed to be) temporary?

Thank you!
