In the current market, even small differences in mortgage strategy can lead to significant long-term savings. Many landlords assume that remortgaging is just a routine renewal exercise — but handled correctly, it can be one of the most powerful tools to increase profit, unlock equity, and future-proof a portfolio.
At NetRent, our role is to identify opportunities where others see only renewal dates. In this real-world example, a single remortgage review delivered over £1,200 in annual savings for one experienced landlord — without extending borrowing or increasing risk.
1. The Situation: A Landlord Approaching Renewal
Our client, an established landlord based in the North West, owned three rental properties — all under five-year fixed-rate buy-to-let mortgages. One of those mortgages was approaching its renewal date in early 2026.
Their original lender had offered a retention deal: a 5.79% two-year fixed rate that would allow the client to renew easily without paperwork or valuation. Like many landlords, they considered simply accepting it for convenience.
However, the landlord contacted NetRent for a portfolio review — not expecting major changes, but wanting reassurance that the offer was fair.
2. The Challenge: Tight Lender Criteria and Rising Costs
The client’s property — a well-maintained semi-detached home valued at £210,000 — had a remaining mortgage balance of £147,000. Their monthly payment was due to rise from £640 to £730 under the proposed new rate, significantly reducing monthly profit.
The landlord’s concern was that many lenders were tightening affordability tests, particularly on single-unit properties with mid-range rental yields. They assumed remortgaging externally would be complicated or even rejected.
Our goal was to find a way to reduce cost and secure a longer-term rate, while ensuring compliance with stricter affordability and stress-testing rules.
3. The NetRent Approach: Portfolio-Level Strategy
Rather than focusing solely on the renewing property, our team reviewed the client’s entire portfolio. We discovered that one of their other properties had appreciated in value by nearly 12% over the past three years — improving its loan-to-value (LTV) ratio considerably.
By using that additional equity to rebalance borrowing across both mortgages, we were able to lower the overall LTV and qualify the client for a specialist portfolio rate not available to individual landlords.
After identifying three suitable lenders, we recommended a five-year fixed product at 5.19% — saving both on rate and avoiding repeated remortgage costs in the near future.
4. The Result: Lower Costs, Greater Stability
The outcome was immediate and measurable:
| Factor | Previous Lender Offer | New NetRent Solution |
|---|---|---|
| Rate | 5.79% fixed (2 years) | 5.19% fixed (5 years) |
| Monthly Payment | £730 | £630 |
| Annual Savings | – | £1,200 |
| Future Security | Renewal in 2 years | Protected for 5 years |
| Portfolio LTV | 71% | 63% |
In addition to direct savings, the longer-term fix provided rate certainty through to 2031 — critical in an environment of fluctuating market conditions.
5. The Hidden Benefit: Unlocking Equity for Improvement
With the remortgage complete, our client also gained access to a small equity release facility of £15,000. This was later used to upgrade insulation and replace windows in one property, improving its EPC rating from D to C — further enhancing compliance and tenant appeal.
In effect, the remortgage achieved three outcomes at once:
-
Lowered monthly costs.
-
Extended rate security.
-
Funded an energy upgrade that improved long-term asset value.
6. Lessons for Other Landlords
This case highlights a critical truth: the best mortgage deal isn’t always the easiest or most obvious one. By analysing your portfolio as a whole — not as isolated loans — it’s often possible to unlock better rates, terms, and flexibility.
Key takeaways:
-
Never accept a retention offer without a review. Lenders rarely offer their most competitive rates to existing clients automatically.
-
Use portfolio strength to your advantage. Strong performance on one property can improve borrowing terms across others.
-
Act early. Starting six months before renewal gives time to explore all available options and avoid rushed decisions.
-
Work with specialists. Expert brokers can access lenders and products that aren’t available directly to landlords.

In a market where margins are under pressure, small percentage differences can produce large financial impacts. As this case shows, a single well-timed remortgage can pay for itself many times over.
