HMO deposit / LTV needed
Searchers ask what deposit an HMO mortgage “needs.” There is no single national percentage AgentHMO can publish as fact. Loan-to-value (LTV) caps sit in each lender’s criteria and move with product, borrower experience, licence status and property type.
How deposit and LTV work for HMO lending
LTV is the loan divided by the lender’s valuation (not necessarily the price you hoped for). The deposit is typically the gap you fund in cash at completion, plus fees and tax where due. HMO products often quote different maximum LTVs from standard buy-to-let. A broker may describe ranges they see today — treat any figure not on your own illustration as not confirmed. Read the HMO mortgage guide and the HMO mortgage valuation guide before you lock a personal “I only need X%” story. Forum screenshots of someone else’s offer are not your underwriting.
Themes lenders discuss
Experience as a landlord, clean credit, income evidence, maximum occupancy, licence pathway and planning use class all appear in criteria packs. First-time HMO landlords sometimes face tighter LTVs or fewer products. Larger or sui generis stock can sit outside standard matrices. Portfolio landlords may be underwritten on a different basis again. None of that promises you will or will not get an offer.
Deposit versus the rest of completion cash
Cash at completion also covers Stamp Duty Land Tax where due — see the HMO stamp duty guide — plus valuation fees, broker fees, solicitor costs and often a works buffer. A headline deposit percentage that ignores those lines underfunds the day. The HMO finance guide covers wider process reading. Gifted deposits, overseas funds and company share capital each bring evidence requirements your solicitor and lender will specify. Do not assume a personal savings transfer is the only pattern.
Worked illustration (illustrative only)
Suppose a lender’s illustration shows a maximum LTV against a panel valuation. Your cash need is price (or valuation, if lower rules apply) minus loan, plus SDLT and fees. If works are required before occupation, add that schedule. If the valuation comes in below price, LTV maths can force more cash or a renegotiation. This page will not invent a sterling example that readers treat as a quote.
How to use calculators without fooling yourself
The HMO mortgage calculator needs a loan amount you choose — it does not set LTV policy or underwrite you. Pair calculator output with a human FCA-authorised broker who has read current criteria.
Licensing and insurance still matter to many lenders
Many lenders want a clear licence pathway — see the HMO licensing guide — and HMO-capable insurance disclosed — see the HMO property insurance guide. Soft asset value: HMO valuations. The HMO lenders directory is a directory, not a recommendation.
Remortgage equity and capital raise
Raising capital against an existing HMO uses the same LTV logic against a panel valuation, not against an online estimate. See the HMO remortgage guide for process shape. Early repayment charges on the current product can erase the benefit of a lower headline rate.
Portfolio and limited-company angles
Portfolio landlords may be assessed across multiple securities. Limited-company purchases can change product menus and deposit expectations again. Neither structure is inherently better for LTV — criteria and guidance decide. Do not incorporate solely because a social media thread claimed companies get higher leverage. If you already hold HMO stock, bring rent schedules, licence copies and prior valuation reports to the broker conversation early. Missing paperwork lengthens the path more than shaving a quarter-point of rate shopping.
Options instead of stretching LTV
Smaller purchase price; more cash in; joint purchase structures your solicitor designs; delaying until experience criteria improve; or buying stock that fits a product you can actually obtain. Stretching LTV to “make the deal work” is how thin buffers die when valuation or works surprise you.
Common mistakes
- Treating asking price as the valuation - Ignoring SDLT and fees in the cash stack - Assuming residential first-time buyer deposit schemes apply to HMO investment stock - Shopping rate before confirming product eligibility - Forgetting works reserves after a “maximum LTV” illustration
Where to get regulated help
FCA-authorised mortgage brokers, solicitors and insurers handle the regulated parts of this decision. AgentHMO will not recommend a product or quote a “typical HMO deposit %” as fact.
Frequently asked questions
What deposit do I need for an HMO mortgage?
Ask an FCA-authorised broker against current criteria for your file. No universal AgentHMO percentage exists, because lender rules differ.
Is an HMO mortgage deposit the same as a first-time buyer deposit?
Products and criteria often differ from residential first-time buyer schemes. Do not assume those schemes apply to investment HMOs.
Can I use equity from another property as the deposit?
Sometimes a remortgage or further advance can raise cash — criteria and professional guidance are required. It is not automatic.
Does a higher deposit guarantee an offer?
A larger deposit can help but does not guarantee an offer. Eligibility is wider than LTV alone.
