Frequently asked questions
What counts as move-in cost?
Deposit plus first month rent plus the agency fee and any one-time setup costs — the cash you need before living there.
Does it model rent increases?
Yes — the annual increase field compounds the rent for leases longer than a year.
Why compare the average monthly cost?
It spreads one-time expenses — agency fee, moving costs — across every month, so two listings with different fee structures can be compared on what you actually spend per month rather than the headline rent.
