Calculators for the dates that actually matter
Letting a property in England runs on a handful of statutory deadlines, and most of them are counted in a way that catches people out — a deposit deadline that is 29 days rather than 30, a notice period set by whichever ground is longest, a certificate with no renewal date at all.
Each of these runs the same code the Tenarize product runs, from a copy kept in step by a check that fails our build if the two disagree. Use them without signing up for anything.

Cost your letting agent out
Not a statutory deadline, but the other number landlords want before they commit to anything: what a full-management fee actually costs against doing it yourself, on your own figures.
