Property Strategist
'I trust Kristina with every aspect of my portfolio — from agency coordination to viewings and full refurbishments. She’s practical, design-savvy, and always finds a cost-effective way.'
~ Private Investor, Cambridge
I work with homeowners, landlords and property investors to prepare, refine and reposition residential properties — whether for sale, rent or strategic improvement.
As Founder of Sierra Mike and a Property Strategist, I combine insight-led interior design with disciplined refurbishment management and property advisory. My focus is on decisions that materially improve perception and performance — not just appearances.
Over the past five years, I’ve managed and refurbished more than 50 residential properties across Cambridgeshire. That experience has shaped an approach that prioritises investment wisely, coordinates trades intelligently and avoids unnecessary spend — all in service of stronger first impressions and better outcomes.
Many properties underperform not because of the market, but because early decisions lack direction. Establishing clarity before work begins — in presentation, flow, finishes and functional layout — tends to be the difference between listings that linger and those that attract confident offers.
Alongside advisory and refurbishment work, I develop Sierra Mike Original — curated, refined furniture collections rooted in English inter-war pieces, produced in limited runs for clients and designers seeking distinctive character.
I am also the author of Style to Let, a practical guide for landlords and hosts focused on increasing rental appeal and long-term returns.
