What it is

A back-office service for landlords with a few properties. You keep track of rent payments, chase arrears, organise tenancy paperwork and renewals, log expenses and prepare tidy records for their accountant. You do not manage repairs or visit properties.

Your first three steps

  1. Learn the basics of letting paperwork and landlord record keeping, and decide exactly which tasks you will and will not offer
  2. Set up a simple monthly fee list, a client agreement and a secure way to store documents and bank information
  3. Contact local landlords through landlord groups, social media and small letting agents, and offer to take on your first one or two properties at an introductory rate
Who pays

Private landlords with one to ten properties who are short on time, plus small letting agents who want extra admin help.

How it makes money

A monthly fee per property or a fixed monthly retainer per landlord, with extra charges for one-off jobs such as tenancy renewals or year-end record preparation.

  • Data protection: check whether you need to register with the ICO and how to store tenant details safely
  • Check the anti-money laundering registration rules with HMRC if you offer anything that looks like accountancy or bookkeeping services
  • Deposit protection, right to rent checks and other letting rules differ between England, Scotland, Wales and Northern Ireland, so be clear what is the landlord's responsibility
  • Check your tenancy or mortgage terms allow you to work from home
