Renting out your home: the accidental landlord's checklist

Moving out and letting your home instead of selling? Here's what to sort with your lender, insurer and HMRC before the tenant moves in.

Updated 18 October 2026

The short version

If you're moving out and want to let your home rather than sell it, there are six things to sort before a tenant moves in:

  1. Your mortgage lender's permission, called consent to let, or a switch to a buy-to-let mortgage.
  2. Landlord insurance in place of your home insurance.
  3. The safety checks and paperwork every let needs.
  4. Tax: registering for Self Assessment, and what letting means when you sell.
  5. Your lease, if it's a leasehold flat.
  6. How you'd get it back if you want to move home again.

1. Your mortgage

A residential mortgage only lets you live in the property. Letting it without permission breaks your mortgage terms. You have two options:

2. Insurance

Home insurance usually stops covering you once the property is let. You need landlord buildings insurance, and contents cover if you leave furniture. Many landlords add rent guarantee and liability cover.

3. Safety checks and paperwork

Our landlord compliance checklist takes you through the full list in order.

4. Tax

5. Leasehold flats

Read your lease. Many need the freeholder's permission to let, and some ban short lets. Tell the managing agent who the tenant is.

6. Getting your home back

Since 1 May 2026 every tenancy is periodic, and you can't end one without a legal reason. If you want to move back in, you can use the moving-in ground, but not in the first 12 months of the tenancy, and you must give four months' notice. If you decide to sell, the selling ground has the same rules. See our Section 8 guide.

Is letting better than selling?

It depends on the rent, your mortgage, tax and how fast you expect prices to rise. Compare the two with the sell or keep calculator, check what your home would rent for with the average rent checker, and see the full costs in our landlord costs guide.

Questions landlords ask

Can I rent out my house without telling my mortgage company?

No. Letting without permission breaks the terms of a residential mortgage, and the lender could ask you to repay the loan or switch you to a higher rate. Ask for consent to let, or remortgage to a buy-to-let mortgage.

How long does consent to let last?

Usually 6 to 12 months at a time, and some lenders allow renewals. Each lender sets its own rules, fees and any rate increase.

Do I pay capital gains tax if I let my old home?

Possibly, when you sell. Private residence relief covers the time you lived there, plus the final nine months. The let period is usually taxable, after the £3,000 annual allowance.

Can I move back into my house after renting it out?

Yes, using the moving-in ground. You can't use it in the first 12 months of a tenancy, and you must give the tenant four months' notice.
