London HMO conversion: 3 bed house to 4 bed, 3 bath HMO
London · HMO conversion
Investment opportunity in London: 3-bed property with potential to convert into a 4-bed HMO. Strong cashflow and long-term growth potential. Enquire now.
The property is located within a strong rental area and offers the opportunity to convert the existing layout into a 4-bedroom, 3-bathroom HMO, significantly increasing rental income and creating substantial additional value.
Unlike many heavy refurbishment projects, this is primarily a reconfiguration and value-add opportunity rather than a full redevelopment, making it suitable for investors seeking a combination of cashflow, equity creation, and long-term growth.

In simple terms
This opportunity combines three of the key drivers of successful property investing: strong cashflow, forced appreciation, and long-term capital growth.
By converting a standard 3-bedroom property into a 4-bedroom, 3-bathroom HMO, the investor has the potential to significantly increase both rental income and property value. Whether the objective is to retain the property for long-term income, recycle capital through a BRRR strategy, or ultimately sell after benefiting from both rental income and market growth, the project offers multiple potential routes to creating long-term wealth through property.
The ability to fund the conversion using personal funds, refurbishment finance, or potentially through a joint venture partner also creates flexibility for investors with different levels of available capital.
Please note that whilst the figures above assume a standard 25% deposit buy-to-let purchase, the property may also be suitable for buyers wishing to purchase with a residential mortgage and a lower deposit, subject to lender criteria and individual circumstances.
If this opportunity is of interest, we encourage you to get in touch with us today to discuss the property in more detail. All opportunities are offered on a first-come, first-served basis and remain available only until reserved.
Entry cash from £116,000.
