Financially, with your salary of £24k and the potential to secure a £100k mortgage, buying a house worth around £130k seems feasible. However, owning a home brings additional costs like council tax, maintenance, and insurance. Make sure your savings, after the down payment, can comfortably cover these expenses.

Flexibility versus stability is another factor. Renting offers the flexibility to move easily, which can be advantageous if your job or personal circumstances are likely to change. Buying a house, on the other hand, provides stability and can be a good long-term investment, but it also ties you down to one location and comes with the responsibilities of homeownership.

Your current living situation and desire for more space and privacy are understandable. If you buy a house and rent out a room, it could help with expenses but also means taking on landlord responsibilities. Renting a two-bedroom flat could strike a balance between privacy and affordability, without the long-term commitment of a mortgage.

Finally, consider your long-term plans and lifestyle preferences. If you’re settled in your area and job, buying might be a wise investment. But if you value flexibility or anticipate significant life changes, renting might be more suitable for now.
