Landlords
Thinking of Renting Out Your Home? Sell vs Let
Renting out your home can provide income and keep an asset that may grow, but it makes you a landlord with real duties: tax on rental income, safety regulations (gas, electrical, EPC), deposit protection, void periods and maintenance. You’ll likely need consent to let or a buy-to-let mortgage. Letting suits those wanting long-term income who can absorb the costs and hassle; selling suits those wanting a clean exit and the capital now.

What being a landlord involves
Letting your home isn’t passive income — it makes you a landlord with legal duties. You must protect the tenant’s deposit in a government scheme, provide an annual gas safety certificate, a valid electrical (EICR), an EPC at the right rating, smoke/CO alarms, and follow the right-to-rent and tenancy rules. You’re responsible for repairs and maintenance, and you carry the risk of void periods, arrears and difficult tenants. Many use a letting agent (typically 8-15% of rent) to manage this.
The costs and the tax
| Cost | Detail |
|---|---|
| Income tax | On rental profit, at your marginal rate |
| Letting agent | ~8-15% of rent if fully managed |
| Safety & compliance | Gas, EICR, EPC, alarms, licensing |
| Maintenance & voids | Repairs, periods with no rent |
| Mortgage | Consent to let or buy-to-let rate |
Rental income is taxable, and mortgage-interest relief is restricted, so model the net return, not just the headline rent.
Consent to let and the mortgage
If your home has a residential mortgage, you can’t just let it — you need "consent to let" from your lender, or to switch to a buy-to-let mortgage (usually at a higher rate). Letting without consent breaches your mortgage terms. There may also be selective licensing in your area requiring a council licence. Sort the mortgage and licensing position before committing to let, as they affect whether letting is viable and what it costs.
Sell vs let: which suits you
Letting makes sense if you want long-term income and exposure to house-price growth, can absorb the costs, regulation and hassle, and ideally have a reason to keep this property. Selling makes sense if you want a clean break, need the capital now (for your next home or other plans), don’t want landlord responsibilities, or the numbers don’t stack up after tax and costs. There’s no universal answer — it depends on your finances, plans and appetite for being a landlord (see sell or rent?).
If selling is the right call
If you decide a clean sale beats becoming a landlord — perhaps you’re relocating, the numbers don’t work, or you simply don’t want the hassle — selling releases your full equity now. For a quick, certain exit, a cash buyer can complete in 7-28 days, with no chain and no months of marketing. If you’ve already let the property and want out, you can sell tenanted to an investor too (see selling with tenants). Weigh the net rental return against a clean sale before deciding.

Frequently asked questions
Straight answers, no sales talk
Should I sell or rent out my home?
Letting suits those wanting long-term income who can absorb the costs, tax and hassle; selling suits those wanting a clean exit and the capital now. It depends on your finances and plans.
What are a landlord’s legal duties?
Protecting the deposit, annual gas safety certificate, valid EICR, EPC at the right rating, smoke/CO alarms, right-to-rent checks, repairs, and following tenancy rules.
Do I pay tax on rental income?
Yes — rental profit is taxable at your marginal rate, and mortgage-interest relief is restricted. Model the net return after tax and costs, not just the headline rent.
Can I rent out a house with a residential mortgage?
Not without permission — you need consent to let from your lender or a buy-to-let mortgage. Letting without consent breaches your mortgage terms.
What are the downsides of letting?
Void periods with no rent, arrears, difficult tenants, ongoing maintenance, compliance costs, tax, and the time and hassle of being a landlord (or agent fees to manage it).
How do I sell instead of letting?
A cash buyer can complete in 7-28 days with no chain, releasing your full equity now. If already let, you can sell tenanted to an investor.
