If your Split Pay isn't at a 50/50 split yet, your approved amount grows automatically 5% each month you pay your second payment on time — up to a maximum of 50%.
Example: if your second payment is $300 this month:
Pay it on time → next month it'll be $315 (5% more)
Pay that one on time → next month it'll be $330.75
Keep going until you hit 50% of your total rent
This happens automatically. You don't need to ask, request it, or do anything other than pay on time.
The other path to increase your approval:
Reapplying (after eligibility expires or if you want a fresh evaluation) starts from scratch with your current financial profile. Could go up, could stay the same, could go down — it's a fresh look. See the FAQ on Will I get the same approval amount if I reapply?.
The most reliable path is just paying on time and letting the 5% compound.
