Whether you are managing a single rental or a sprawling portfolio, understanding the true value of your assets is not just an accounting exercise; it is the foundation of your investment strategy. It’s important to keep on top of what your assets are worth so you can take timely decisions about when to sell and what to hold.
Property Valuation 101
When valuing properties, we follow a stripped-back version of a professional surveyor’s process. It is essential to focus on sold prices rather than asking prices
1. Do your homework
- Ideal Window: Look for properties sold within the last six months
- Proximity: Focus on a quarter-mile radius initially
- Historical Context: If data is sparse, expand the distance before expanding the timeline
- Market Temperature: Take specific years with a “pinch of salt.” For instance, the hyper-inflated market of 2021 remains a historical outlier that can skew current expectations
2. Automated Valuation Models (AVMs)
Technology has democratized data, though accuracy varies:
- Free Tools: Platforms like Zoopla are excellent for tracking portfolio-wide trends, even if they sometimes miss the “idiosyncratic” nuances of an individual house
- Professional Grade: We utilize Hometrack, a tool used by 19 out of the top 20 UK lenders. Knowing what Hometrack shows allows you to see exactly what your lender sees, which is incredibly helpful for anticipating decisions.
Do it regularly but not frequently
While most trading businesses obsess over their Profit and Loss (P&L) statements monthly, property investment requires a different focus. P&Ls are often less useful when you are doing significant refurbishments because value-adding projects and ongoing maintenance often get blended together.
We tend to revalue “steady-state” properties at least once a year, but we may review specific assets quarterly depending on how the market is moving.
Attention to details
Properties are often commoditized (like standard terraces or semis), but value is often hidden in “solvable problems”. When a property is priced attractively, there is usually a reason—80% to 90% of the time, there is a problem that needs solving.
- Permanent Problems: Issues with location, aspect, or “undesirable neighbors” may persist19191919.
- Solvable Nuances: Small features can add outsized value. In suburban pockets where parking is scarce, a dedicated space can add 10% or more to a property’s value. Adding a porch or small yard to a terrace can also make a difference.
Watch the liquidity
A common trap for landlords is attributing a paper valuation to real world cash. In reality, once you factor in estate agent fees, solicitors, and council tax during voids, you may only realize 92% to 93% of that value.
To keep our business robust, we typically turn over approximately 3% of our stock every year. This “proves liquidity” and ensures our valuations are anchored in real-world results. Furthermore, selling periodically helps maintain a healthy loan-to-value (LTV) across the portfolio without relying solely on escalating debt.
Strategy Tip: Selling to a “tenant in situ” can be advantageous for both parties, as it avoids agent fees and rental voids.
A Mantra for 2026
One of Adam’s favourite adiges comes from a Dickens’ character, Wilkins Micawber, who can teach anyone about wealth management:
“Annual income twenty pounds, annual expenditure nineteen pounds nineteen and six: result -happiness. Annual income twenty pounds, annual expenditure twenty pounds ought and six: result – misery.”
With costs rising and councils increasingly looking to top up their budgets from landlords’ pockets, this focus on margins is vital. Success this year won’t come from “highfalutin” New Year’s resolutions; it will come from the “boring” graft of daily market research and ensuring your expenditure never overtakes your income.
