Rent to SA (R2SA) is a property strategy where you lease a property from a landlord on a guaranteed-rent agreement, furnish it, and sublet it on short-term let platforms such as Airbnb or Booking.com at a higher nightly rate. You keep the difference between what guests pay and what you pay the landlord, minus all operating costs.
Unlike buy-to-let, you do not need to purchase the property or obtain a mortgage. Your upfront capital covers setup costs: deposit or bond, first month's rent, furniture and staging, and any sourcing or legal fees. For a typical one or two-bed, this runs to £4,000-8,000.
The profit potential is real. A well-run deal in a location with genuine short-let demand can produce £400-700 per month net cashflow. The problem is not the strategy. It is the assumptions investors use when evaluating deals.
Here is a realistic two-bed in a UK city, run through two occupancy assumptions.
The deal:
Monthly rent to landlord: £900
Average nightly rate: £130
Fixed costs (council tax, utilities, broadband, insurance): £425/month
Cleaning and linen: £400/month
Airbnb platform fee: 15% of gross revenue
Setup capital: £900 deposit + £900 first month + £3,500 furniture + £500 sourcing = £5,800
Scenario A: Optimistic (80% occupancy)
Gross revenue: £130 x 24.3 days = £3,159/month Platform fee: £3,159 x 15% = £474 Total expenses: £900 + £425 + £400 + £474 = £2,199 Net monthly cashflow: £960 Annual profit: £11,520 ROI: 199%
Scenario B: Realistic (65% occupancy)
Gross revenue: £130 x 19.8 days = £2,569/month Platform fee: £2,569 x 15% = £385 Total expenses: £900 + £425 + £400 + £385 = £2,110 Net monthly cashflow: £459 Annual profit: £5,508 ROI: 95%
Same property. Same landlord. Same nightly rate. The difference is 15 percentage points of occupancy, and it separates a strong deal from one that barely recovers its setup costs in a year.
Scenario A is the number that gets shown in R2SA training courses. Scenario B is closer to what you should use to decide whether to sign.
R2SA has two non-negotiable legal requirements that new operators sometimes overlook.
Landlord permission. A standard Assured Shorthold Tenancy does not permit subletting as serviced accommodation. You need explicit written permission from the landlord in your agreement. The landlord also needs to verify that their own mortgage terms and building lease allow short-term subletting. Leaseholders in blocks of flats often face additional head lease restrictions. Confirm all three before signing anything.
Specialist insurance. Standard BTL and HMO insurance does not cover short-term let operations. You need SA-specific landlord insurance that covers guest liability, property damage, and loss of income. Operating without the correct insurance cover leaves you exposed to claims that a standard policy will not pay out on.
Both requirements are straightforward to fulfil when you build them into your setup process. They become expensive problems when operators skip them.
Check Airbnb comps before assuming a nightly rate. Search your target location on Airbnb filtered by property type and bedrooms, set to available dates in your target month. Use the median listed rate, not the top end of the range.
Model at 65% occupancy. Run your full cost model at 65% occupancy first. If the cashflow is still positive and ROI is acceptable, raise it to 70% to see the upside. Never start with best-case occupancy.
Cost every variable line. Include platform fee, cleaning per month, consumables estimate, and management fee if you plan to use an operator. Missing any one of these from your model produces an overstated cashflow figure.
Total your setup capital accurately. Deposit plus first month's rent plus actual furniture costs plus all fees. Use the real furniture budget, not a wish-list number.
Confirm the legal position before you proceed. Landlord permission in writing, mortgage terms checked, building lease reviewed, correct insurance sourced. These are not optional steps to complete after signing.
Use the Rent to SA Calculator to run all five scenarios before you commit to a deal.
