A guarantee is only ever as good as the balance sheet behind it. Some are genuine risk transfers. Some are your own money returned slowly. Here is how to tell which one you are being offered.
A rental guarantee is a developer or operator commitment to pay you a stated return for a stated period, usually the first few years after completion, whether or not the property earns it. Guarantees are not inherently dishonest and plenty are met in full. But a guarantee is only ever as good as the balance sheet behind it, and it is routinely used to make a price look like a yield.
The operator believes the building will earn more than the guaranteed figure and is comfortable carrying the early-years risk to get the scheme let and stabilised. This is the honest version, and it usually looks conservative — a guaranteed rate at or below what comparable stabilised buildings actually achieve.
The guaranteed payments have been priced into the purchase price. You pay more up front and receive it back as ‘income’ over the guarantee period. Nothing has been guaranteed except the arithmetic. The tell is a guaranteed rate well above what the local market achieves, on a price above comparable unguaranteed stock.
The guarantee is real but expires, and the market rate afterwards is materially lower. Buyers who modelled the guaranteed years and assumed continuation get a permanent step down in year four or six — typically at the same moment the building needs its first refurbishment cycle.
| Question | What a good answer looks like |
|---|---|
| Who is the counterparty — developer, operator, or a special-purpose company? | A named entity with assets, not a company incorporated for the scheme |
| Is it gross or net of service charge and sinking fund? | Stated explicitly; a “net of all costs” guarantee is worth far more than a gross one |
| How does the guaranteed rate compare with what stabilised buildings nearby actually achieve? | At or below it. A guarantee far above the market is a pricing device |
| Is the purchase price higher than comparable unguaranteed stock? | If yes, you may be buying your own guarantee |
| What happens in year one after it expires? | Evidence from an existing building by the same operator, not a projection |
| Is it secured — bank guarantee, escrow, retention? | Some form of security beyond a contractual promise |
| What are your remedies if it is not paid? | A defined process, in a jurisdiction you could realistically use |
| How many owner nights are you giving up to receive it? | Stated in nights, including whether peak weeks are excluded |
Put the guaranteed scheme and an equivalent unguaranteed one side by side on price per square metre. If the guaranteed unit costs more, work out how much more, and how many years of the guaranteed payment it takes to recover the difference. If that number is close to the length of the guarantee, you are being sold your own capital back with a certificate attached.
For context on what is actually achievable without a guarantee: realistic net yields on managed Phuket stock sit in the mid-single-digits — in the region of 4–5% — after the management split, service charge, sinking fund, vacancy and tax. Those figures are not guaranteed and your capital is at risk. Treat any guaranteed rate materially above that range as a question to be answered rather than a benefit to be counted. Our existing note on whether to trust a rental guarantee covers the background, and choosing a reputable developer covers the counterparty question.
Want a guarantee checked against what the building actually earns?
See if you qualify →Some are, and plenty are paid in full. But a guarantee is only as strong as the entity behind it, so the first question is who the counterparty is and whether it has assets. The second is whether the guaranteed rate is at or below what comparable stabilised buildings actually achieve - a rate far above the market is usually a pricing device rather than a benefit.
Compare price per square metre against equivalent unguaranteed stock. Work out how many years of guaranteed payments it takes to recover the difference. If that is close to the length of the guarantee, you are effectively receiving your own capital back.
The property reverts to market performance, which is often materially lower than the guaranteed rate, and it frequently coincides with the first refurbishment cycle. Ask for evidence of what happened in year one after expiry at an existing building run by the same operator.
It varies, and the difference is large. A guarantee stated net of service charge and sinking fund is worth considerably more than the same headline figure quoted gross. Get it in writing.
