London 3-bed at £585,000 and £1,525 rent: does the yield work?

Landlord
On the headline figures this could pass as a long-term investment, but I am hesitant to make it our first rental. The London 3-bed is £585,000 and the proposed rent is £1,525 a month, so the gross yield is only about 3.1%.

I have allowed for empty periods, management, routine upkeep and tenant turnover. Finance would be assessed separately. Before going further, I need to know the service charge, any ground rent or planned works, and who carries property-related charges while the flat is vacant. At this margin, would you keep investigating only if those figures were unusually low, or stop now?
 
For an apartment, I would focus first on service charges and exposure to major building works. A 3.1% gross yield leaves very little room for either, especially before finance and purchase costs. I would not treat it as an income deal until you know what the flat itself must pay, rather than judging the building only by appearance.
 
Do you know the tenure, current service charge, any ground rent, and whether major works are planned? I’d also want evidence supporting £1,525 rather than relying on an asking-rent estimate. Those missing facts could change the answer more than fine-tuning your vacancy allowance.
 
Before you have to commit, decide whether this is an income purchase or a long-term value bet. The distinction matters more than whether 3.1% looks low in isolation.

For example, a buyer focused on future value might tolerate little current cash flow. That does not make the same flat suitable for someone who needs dependable rent after service charges, turnover and repairs. I would first confirm the building costs and achievable rent, calculate the unlevered result, and only then decide whether the alternative investment case is one you actually want.
 
Annual rent is £18,300, so the stated gross yield is about right. The useful exercise is to deduct all property-level costs first and calculate an unlevered net yield, then add the proposed financing separately. Otherwise a cheap or expensive mortgage can disguise whether the apartment itself is performing.
 
Thanks. I don’t yet have confirmed service-charge, ground-rent or planned-works figures, so that is clearly the gap rather than something I should estimate casually. The £1,525 rent also needs firmer local support. I’m going to pause the financing comparison until those building and rent details are established.
 
That sounds sensible. Once you have them, run at least three versions: normal occupancy, a tenant change with a void and reletting costs, and a year containing an exceptional building charge. If one ordinary setback turns the annual cash flow negative before tax, you’ll know how dependent the deal is on perfect execution.
 
Tenant turnover deserves more weight than a simple vacancy percentage. A change can combine lost rent, management or letting costs, cleaning and repairs. Also establish who covers council tax during empty periods and whether your intended tenant arrangement creates any local licensing or compliance issue. The details can vary by borough and occupancy pattern.
 
The rent-to-price relationship also makes me wonder whether the rent is understated, the price reflects something not visible in the rental return, or the comparison is mismatched. Verify nearby evidence for genuinely similar 3-bed apartments: same condition, size, location and letting arrangement. Don’t improve the spreadsheet by assuming a higher rent without that evidence.
 
Watch the insurance line as well. Building insurance may be collected through an apartment’s service charge, while other landlord cover could remain separate. Find out what is actually included so you neither omit a cost nor count it twice. The same principle applies to maintenance inside the flat versus communal building expenditure.
 
I’d calculate yield on the full cash committed, not only £585,000. Acquisition taxes and transaction costs reduce the effective return even though they do not appear in the headline yield. Tax treatment then depends on ownership and financing circumstances, so that part is worth confirming for your specific UK position rather than applying a generic online example.
 
Financing sensitivity needs more than today’s expected payment. Test a higher cost when the borrowing is next repriced, along with a void at the same time. A deal can appear manageable when those risks are modelled separately but become uncomfortable when they coincide. Also distinguish monthly cash flow from principal repayment, if applicable.
 
Before deciding, I’d assemble four things: verified achievable rent, complete recurring building charges, any known major-work exposure, and the exact finance terms. Then calculate net operating income before debt, cash flow after debt, and the result after one tenant turnover. At 3.1% gross, small omissions matter more than they would on a wider-margin property.
 
Given the update, there isn’t enough information yet to name a defensible net yield. Reverse the question instead: set the minimum annual cash return you require for management effort, illiquidity and unexpected costs, then work out the maximum purchase price consistent with it. If that price is well below £585,000 after confirmed charges, the answer is clear without debating London appreciation.
