Maximise Your Portfolio Yield with SL&M Ltd
Pre-Vetted Portfolio Stress-Testing
We manually stress-test your portfolio against real lender ICR criteria before you pay any valuation fees.
Future-Proofed Funding Structures
We map out your borrowing three deals ahead so you do not hit the four-property portfolio landlord ceiling by accident.
True Advisory Independence
​SL&M Ltd operates with zero preferred lender panels, meaning our advice is entirely un-biased and focused solely on your yield.
Navigating the 4+ Portfolio Landlord Threshold
Once you own four or more mortgaged properties, mainstream high-street banks change how they view your risk profile. The introduction of strict portfolio underwriting rules means that growth actually shrinks your borrowing options unless you plan around it. At SL&M Ltd, we specialise in placing complex, multi-property buy-to-let finance with specialist lenders. We understand how your ownership structure impacts your borrowing capacity, allowing you to unlock equity and keep your property business moving forward seamlessly.
