A void period is any time your property sits empty between tenants. It is the quiet cost that yield calculations love to ignore, and it can turn a good-looking return into an ordinary one. The mortgage, insurance and council tax do not pause just because the rent does.
What a void actually costs
Take a property renting at £825 a month. Every empty month is £825 of income gone, and you are usually paying the council tax and standing costs on top. Two void months a year is not just two months of lost rent; it is close to a sixth of your annual income, plus extra bills. On paper the property might show an 8% yield. With regular voids, the money you keep tells a very different story.
Why voids happen
- Reletting too late. Waiting until a tenant has left before advertising guarantees an empty month or two.
- The wrong price. Over-ask and the property sits; the lost rent usually costs more than the higher rent would ever have earned.
- Tired condition. A property that shows poorly takes longer to let and attracts weaker applicants.
- Weak area demand. Some of this is decided before you buy, which is why the area matters so much.
How to keep the property earning
- Start reletting early. Advertise before the current tenancy ends, so a new tenant can move in soon after the old one leaves.
- Price to let, not to dream. A property let quickly at a fair rent beats one sitting empty at an optimistic one.
- Keep it in good order. Small, prompt maintenance keeps a property lettable and keeps good tenants in place longer.
- Look after good tenants. The cheapest void to avoid is the one that never happens because a reliable tenant chose to stay.
Build voids into your numbers from the start
The investors who are never caught out are the ones who assumed a void allowance before they bought. Put a realistic empty-weeks figure into your net yield, and a property that still works is a property that will keep working. One that only works at 100% occupancy was always going to disappoint.
Common questions
What is a void period in buy-to-let?
A void is any time a rental property sits empty between tenants, earning no rent while the costs continue. Even a few weeks a year meaningfully reduce your real return.
How do I reduce void periods?
Price the rent to the market, keep the property well presented and maintained, re-let early before a tenancy ends, treat good tenants well so they stay, and choose areas with strong demand. Always budget a void allowance even if you expect none.
