Void Periods in Rent to Rent:
How to Minimise Empty Rooms
Voids are the biggest threat to your rent to rent profit margins. This guide covers every tactic for minimising them — from listing strategy to photography, pricing, pre-marketing, and what to do when a room refuses to let. For more detail, see typical profit per property.
What This Guide Covers
The Real Cost of a Void Room
Unlike traditional buy-to-let where a void means zero income, in rent to rent a void means you continue paying the landlord rent with one fewer income source. Every void week has a direct cash cost:
- A room at £580/month = £134/week income lost
- You still pay: landlord rent, utility bills, insurance
- Net cost of a one-week void in a 5-bed HMO: approximately £134 income lost + £60 additional cost share = £194/week
- A two-week void: £388 cost. A month-long void: £750+
This is why the 75% occupancy stress test matters so much — it builds a void buffer into your deal analysis. But the goal is always to operate well above 75% occupancy. The best operators achieve 92–97% occupancy through excellent listing management, responsive tenant handling, and pre-marketing every departure in advance.

Photography — Your Single Biggest Impact on Void Reduction
Bad photos are the single most common cause of slow letting. A well-furnished room with terrible photos lets slower than a mediocre room with excellent photos. This is not optional.
✅ Do
- Shoot in natural daylight — open curtains, turn all lights on
- Use a wide-angle lens or phone wide mode
- Stage the room — straight bedding, clear desk, towel on hook
- Photograph from corner of room for maximum perceived space
- Include communal areas, kitchen, and bathroom
- Edit brightness and contrast in Lightroom (free app)
- Use portrait orientation for vertical rooms
❌ Don’t
- Shoot at night with artificial light only
- Leave clutter or unmade beds in frame
- Photograph from the doorway (makes rooms look tiny)
- Use bathroom mirror selfies as room photos
- Include previous tenants’ belongings
- Post blurry or dark images
- Use only one photo per room
Minimum 5 photos per listing: room (wide), room (detail), desk/wardrobe, kitchen, communal/bathroom. Budget £100–£150 for a professional photographer once per property — then reuse photos for years.
Pre-Marketing Before a Room Becomes Available
The most effective void reduction tactic is to begin marketing a room before it becomes available. As soon as a tenant gives notice (typically one month), list the room as “available from [date]” on all platforms. This means:
- You have 4 weeks of active marketing before the room is even vacant
- Tenants searching now for next month have time to view and decide
- You can often move the new tenant in within days of the previous one leaving — zero void days
- Even if you need to show the room with the current tenant present (with their permission), this is far better than an empty listing
What to Do When a Room Won’t Let
Check Your Photos and Listing
No enquiries after 7 days = a listing problem. Reshoot photos, rewrite the headline, refresh the description. Check competitor listings in the same area — are you priced correctly?
Adjust the Price
If you have enquiries but no conversions — the room might be overpriced. Drop by £25–£50/month and watch conversion improve. If you have no enquiries at all — drop £40–£60/month immediately.
Use Featured Listings and Boost
Pay for featured placement on SpareRoom (£20–£40/month) to significantly increase visibility. Share on all social platforms and in local Facebook groups.
Reassess Fundamentals
A room not letting after a month in a reasonable market signals one of three things: overpriced, poor presentation, or a local market problem. If you have adjusted price and photos without result, consider whether the overall deal economics still work.
Frequently Asked Questions
How long should a room in a good HMO take to let?
In a good market (Manchester, Bristol, Birmingham city areas) with excellent photos and correct pricing, a well-presented room should receive enquiries within 24–72 hours and be let within 5–10 days. In quieter markets or off-peak periods (mid-December, August in student areas), 2–3 weeks is normal. Anything beyond 3 weeks with no progress signals either a pricing or listing quality issue that needs addressing immediately.
Is SpareRoom still the best platform for HMO rooms?
Yes — SpareRoom remains the dominant platform for room lettings in the UK in 2026. The majority of professional HMO tenants searching for rooms use SpareRoom as their primary search tool. It should always be your first listing platform. Facebook Marketplace is a strong secondary platform and is free — use both simultaneously. The combination of SpareRoom plus Facebook Marketplace covers the majority of serious room-seekers in most UK markets. For more detail, see running a professional HMO.
