Calculations are separated from legal conclusions
A calculator can tell you whether arithmetic matches a stated formula, ledger or cost scenario. A routing tool can identify which billing pattern best matches the document signals you enter. A readiness audit can show which disclosure, evidence or timing layers are missing. None automatically determines whether a formula is permitted, a deadline was missed, or a charge is supported by the lease and evidence.
No hidden “typical renter” assumptions
Dollar amounts start from your documents, not sample rents or fee benchmarks. Generic notice and grace periods are not preselected. State-derived deadlines appear only after the property state is chosen, and replacement proration requires the useful life and claimed portion you want to model.
Letter generators do not preselect your claim
Dispute tools ask for the specific fact, balance, reporting item or missing record you want reviewed. The utility generator changes requested records based on the billing method and problem type. Neither tool pre-fills a conclusion that a charge, collection balance or credit-report entry is wrong.
Your entries stay workflow-first
These tools are designed to work without creating an account. Calculators process numbers in the browser, evidence checklists organize selections for your session, audit tools route missing inputs, and letter generators build text for you to review before you choose whether to copy or send it.
Use the simplest next step
If you only have a confusing line item, start with Check My Charges. For a recurring rental fee, use the Rental Fee Audit when the disclosure, mandatory status or frequency is unclear, then organize missing records in the Rental Fee Evidence Checklist before calculating or requesting documentation. For a final move-out balance, use the Move-Out Bill Audit when you are not sure which record is missing. For a deposit problem, use the Security Deposit Audit and the Security Deposit Evidence Checklist before applying a deadline or itemization rule. For an apartment utility statement, use the Utility Bill Audit when the missing layer is unclear. For a late fee, preserve payment and ledger evidence before testing the timing and formula. If an issue is already at collections or on a credit report, keep that downstream process separate from the original landlord ledger.
