What this means for your budget
Average rents mix older and newer homes, so a newly listed home often costs more than the average. Use this figure as a benchmark when you compare listings, and budget for deposits and fees on top. The 30% rule is a simple guide, not a lender's or landlord's requirement; many landlords use their own income checks.
