Frequently Asked Questions

Varies by state: Some have no limit (Texas, Ohio), many cap at 1-2 months' rent. California limits to 2x for unfurnished, 3x for furnished. New York limits to 1 month. Always check your state's security deposit laws.

Typical allowable deductions: unpaid rent, cleaning beyond normal wear and tear, damage repairs (not normal wear), and lease violation costs. Document everything with photos, receipts, and itemized statements.

State laws vary: 14-60 days is typical. California requires return within 21 days, Texas allows 30 days. Failure to comply can result in penalties—some states allow tenants to collect 2-3x the deposit amount.

It's common to collect first month, last month, and security deposit upfront. However, last month's rent is not a deposit—it cannot be used for damages. Keep them separate and clearly labeled on receipts.
