Buy to Let Mortgage Brokers UK
Specialist UK Buy to Let Mortgage Broker for HNW Landlords
Fox Davidson is a UK buy to let mortgage broker for high net worth and portfolio landlords. We arrange standard BTL, HMO, MUFB, holiday let, limited company SPV and portfolio facilities from £250,000, across the high street BTL arms, the specialist BTL lenders and the private banks. Most of our BTL clients own five or more properties, or are buying their first at a price where the high street stops competing.
Fox Davidson works primarily with high net worth and experienced landlord investors building UK BTL portfolios at scale. Our BTL practice covers standard residential BTL, HMO, MUFB, holiday let, limited company SPV, holdco/subco portfolio structures, and the larger portfolio facilities that operate as credit lines rather than transaction-by-transaction mortgages. We arrange BTL from £250,000 single-property purchases up to £250 million single-lender portfolio facilities.
What we have seen over the years is that landlord investors who structure the financing strategically perform materially better than those who treat each property as a standalone transaction. The structuring decisions on every BTL case (personal name vs SPV, single lender vs multi-lender, asset mix tolerance, exit ladder) shape the long-term financing position more than rate negotiation on the next property. We map these decisions at desktop stage on every new engagement.

Six BTL routes we arrange
Each route targets a specific lender pool and underwriting approach. Most BTL portfolios sit across two or three of these routes by the time they reach 10 properties. We map the cross-route position so each new acquisition fits both the property fundamentals and the wider portfolio strategy.

Speak to usHow HNW landlord BTL differs from standard BTL
The standard BTL market is dominated by aggregators competing on rate for first-time landlords and small-portfolio investors. That is not our market. We work with HNW landlord investors building structured BTL portfolios where the financing strategy shapes the long-term outcome. The two structural decisions on every HNW landlord case are ownership structure (personal name vs SPV vs holdco/subco) and lender consolidation strategy (single-lender portfolio facility vs multi-lender diversification).
On multi-unit blocks the choice of lender decides the valuation basis and therefore the loan. Our MUFB lenders comparison sets out who values on block value, who aggregates the flats and where the LTV ceilings sit.
Most HNW landlord investors qualify under the FCA high net worth definition (£300,000 income or £3 million net assets). High net worth qualification opens up private bank routes for residential portfolio refinance alongside the specialist BTL panel. The combination of specialist BTL pricing on operating portfolio facilities plus private bank capability on HNW personal residential refinance produces the strongest overall financing position for landlord investors carrying substantial personal wealth alongside the portfolio.
For experienced portfolio landlords, the PRA stress test on the whole portfolio is now the binding constraint on the next property purchase. A portfolio whose existing position fails the new lender's stress test will fail the new application regardless of how strong the new property looks individually. We map the portfolio stress position on every new engagement before recommending the next lender choice.
Why use a buy to let mortgage broker instead of going direct?
A buy to let mortgage broker gives you access to the specialist and private bank lenders that do not deal with landlords directly, and a rental cover calculation run across every lender before you apply. The high street BTL arms accept direct applications. Most of the lenders that matter for HMO, MUFB, limited company and portfolio cases only accept business through intermediaries, so a landlord going direct is choosing from the smaller half of the market without knowing it.
The second reason is the stress test. Every lender applies its own interest cover ratio and stress rate, and the same property with the same rent can support a £400,000 loan at one lender and £310,000 at another. We run the rental cover across the active BTL market before recommending a lender, which is the difference between an offer at the loan you need and a declined application after a wasted valuation fee. Around a third of the portfolio cases we take on arrive after a direct application has been declined on the PRA stress position rather than on the property.
The third reason is structure. Personal name or company, single lender or spread, which properties to charge and which to keep unencumbered. Those calls are made once, early, and they shape the financing cost of the whole portfolio for years. A lender's own adviser will not make them for you.
How do I choose a buy to let mortgage broker?
Choose a broker on three things: whether they place the type of BTL you actually hold, whether they run the stress test before the application rather than after, and whether they will tell you when a lender is the wrong fit. Ask how many HMO, MUFB or limited company cases they placed last year, and with which lenders. A broker who names Paragon, Shawbrook, Aldermore, Fleet and the private banks without prompting works in this market. A broker whose answer is a high street lender list does not.
Ask about fees too. We charge a flat broker fee of £495 on residential and buy to let cases, payable on application and disclosed before any work starts. What we do not do is recommend a lender because it pays a higher procuration fee, and the stress test across lenders is the check on that: the recommendation has to hold up on the numbers.

Frequently Asked Questions
What types of BTL mortgage does Fox Davidson arrange?
We arrange the full UK BTL lender panel covering standard residential BTL, HMO, MUFB, holiday let, limited company SPV, holdco/subco portfolio structures, single-lender portfolio facilities and HNW landlord lending through private banks. Our practice focuses on experienced and HNW landlord investors building portfolios at scale, though we also advise on single-property purchases where the structuring decision matters.
What deposit do I need for a BTL mortgage in 2026?
The standard minimum deposit on a residential BTL mortgage is 25% (75% maximum LTV). For limited company BTL SPV, deposit typically rises to 25% to 30%. For HMO and MUFB, 25% to 30%. For holiday let, 25% on standard cases rising to 30% to 35% for first-time landlords or specialist regional cases. For larger portfolio facilities, LTV typically caps at 65% to 70% of aggregate portfolio value.
Should I buy BTL property in personal name or limited company?
For basic rate taxpayers buying a single BTL property as an income asset, personal name ownership is typically still the simpler route. For higher and additional rate taxpayers building a portfolio, limited company ownership has been the default since Section 24 phased in fully in 2020. Companies deduct mortgage interest in full as a business expense, while personal name owners receive only a 20% basic rate tax credit. The decision sits with the accountant; we model the mortgage position under both routes.
When do PRA portfolio landlord rules apply?
The PRA portfolio landlord rules apply from the borrower's fourth mortgaged BTL property at the time of a new mortgage application. From the fourth mortgaged BTL onwards, lender underwriting moves from single-property to portfolio-wide assessment, with portfolio stress test (5.5% to 6.5%), business plan requirement, cash flow projection and concentration checks applied. The threshold counts mortgaged properties only.
What yields do BTL properties typically achieve in 2026?
Standard residential BTL gross yields in 2026 run 5% to 7% across most UK regional markets, with London and the South East at the lower end and northern English cities at the higher end. HMO yields run 8% to 12%. MUFB yields run 7% to 11%. Holiday let yields run 8% to 14% depending on location and operating model. Net yields differ from gross by 1.5 to 3 percentage points depending on operating cost structure.
Can I get a BTL mortgage as a first-time landlord?
Yes. Most standard BTL lenders accept first-time landlord applications, typically requiring strong personal income (£20,000+ minimum, £40,000+ for HMO), 25% to 30% deposit, and a clean credit profile. The lender panel narrows for first-time landlords moving directly into HMO, MUFB or holiday let. For first-time portfolio strategy advice (committing to scale from the first property), we map the long-view structure (SPV, lender consolidation strategy) at the start.
How long does a BTL mortgage take to arrange?
Three to six weeks for standard residential BTL on the high street BTL panel. Five to eight weeks for specialist BTL including HMO and standard MUFB. Six to ten weeks for portfolio cases under PRA rules. Eight to fourteen weeks for complex SPV structures (holdco/subco, pension trust, larger MUFB blocks). Conveyancing and completion add a further three to six weeks.
Why use Fox Davidson for a BTL mortgage?
We work primarily with experienced and HNW landlord investors building portfolios at scale, structuring the financing for the long term rather than transaction-by-transaction. We hold direct BDM relationships across the full UK BTL lender panel including the dedicated specialists, the high street BTL arms, and the private banks for HNW landlord investors. For complex portfolios spanning standard BTL plus HMO plus MUFB plus holiday let, we map the cross-route financing strategy alongside the borrower's accountant.
Do I need a buy to let mortgage broker?
You do not need a broker for a single standard BTL on a high street lender. You do need one for HMO, MUFB, limited company, portfolio and holiday let cases, because most of the lenders that write those products only accept applications through intermediaries and each applies a different rental stress test. The broker's job is to run that test across the market before you apply and to structure the case so the loan you need is the loan you are offered.
What does a buy to let mortgage broker charge?
Fox Davidson charges a flat broker fee of £495 on buy to let cases, payable on application and disclosed in writing before any work starts. Lenders also pay a procuration fee on completion. The fee is the same whichever lender you end up with, so the recommendation is driven by the rental cover calculation and the structure, not by which lender pays more.
