Renters
Turnover costs landlords a month or more of rent. Comparable listings plus a good payment history is a real negotiating position — ask 60 days out.
A $1,600 one-bedroom split as an $825-each two-bedroom frees about $9,300 a year. Worth one honest conversation.
Often $10-$25 a month, and required by many leases anyway. Bundle quotes with auto — and re-shop both yearly.
Emergency rental assistance, 211 and legal aid all work better BEFORE a missed payment than after a filing.

Owners
Worth analyzing when rates fall meaningfully below yours: closing costs against monthly savings against how long you'll stay. A break-even month count, not a vibe.
Same three-quote discipline as auto; check bundling both ways, not just with your current carrier.
Many states offer homestead exemptions and senior/disabled/veteran freezes or deferrals. One application at the county assessor can save hundreds yearly.
