Holiday Let or Buy-to-Let in Bromley: What the Numbers Show
Verdict: Buy-to-let wins decisively. The 90-night cap limits holiday let gross revenue to well under half of what buy-to-let generates, and even at full occupancy, holiday letting cannot match annual rent.
Best For: Buy-to-let investors seeking above-average London yields with lower entry prices than inner boroughs.

Estimates for a typical 3-bedroom house. Figures are modelled from market data; not guaranteed outcomes.
Bromley sits in an appealing position for London investors. Entry prices are well below the London average, while rents remain close to the borough-wide median. The result is a gross yield of 5.1%, compared to 4.6% across London as a whole and 5.7% nationally. For investors priced out of central London boroughs, Bromley offers a way into the London market with stronger income returns.
The borough benefits from good transport links (multiple railway stations into central London, proximity to the Jubilee line extension area) and a mix of housing stock ranging from Victorian terraces to suburban family homes. Prices span from around £476,715 at the lower end to £738,705 for larger properties, giving investors flexibility on entry point.

Investment Bottom Line for Bromley
Bromley is a buy-to-let borough. The 90-night cap on holiday letting reduces short-term rental income so far below buy-to-let levels that the strategy is not financially viable. Buy-to-let delivers a gross yield of 5.1% and a net yield of approximately 2.9% after operating costs, comfortably above the London average.
The FHL tax advantage has been removed, making the financial comparison between holiday letting and buy-to-let more important than ever. In Bromley's case, that comparison is decisive: buy-to-let wins on gross revenue, net income, and operational simplicity.
For investors seeking London exposure with better yields than inner boroughs, Bromley's combination of lower entry prices and solid rental demand makes it worth serious consideration. The key is choosing the right postcode: yields vary across the borough's 57 postcode areas, and the difference between the best and worst can shift the investment case meaningfully.
