Questions to Ask an HMO Mortgage Lender: Essential Checklist

Not all HMO mortgage lenders are equal — and the product that looks cheapest on a comparison table may fail at valuation, licensing, or tenant-type restrictions. Asking the right questions before you pay application fees saves weeks of wasted effort and protects your deal from last-minute downgrades.

Use this checklist when speaking to lenders directly or through a specialist broker. Answers should be in writing where possible (email confirmation from the lender or broker file notes).

Property and HMO Classification

Start with whether the lender will actually finance your property:

1. What is the maximum number of bedrooms / occupants you will lend on?
2. Do you lend on large HMOs (seven or more people) and sui generis properties?
3. Is mandatory or additional HMO licensing required before completion?
4. Do you lend in Article 4 areas — and must planning permission be in place?
5. Will you accept non-standard construction (timber frame, concrete, etc.)?
6. Are studio or room-only conversions acceptable, or must the layout be standard shared house?

If any answer is unclear, cross-check with our HMO licensing guide and planning permission guide.

Loan-to-Value and Deposit

1. What is the maximum LTV for this property type and my experience level?
2. Is LTV based on purchase price, valuation, or the lower of the two?
3. Do you offer better LTV for experienced HMO landlords — and how do you define experience?
4. Is a higher deposit required for first-time landlords or student HMOs?

See typical ranges in our HMO deposit guide.

Rental Income and Affordability

1. What interest coverage ratio (ICR) do you require — 125%, 140%, or higher?
2. At what stressed interest rate do you test affordability (e.g. 5.5%, 7%, 8%)?
3. How do you assess HMO rent — room-by-room schedule or single AST figure?
4. Can I use an agent's rental appraisal, or only the surveyor's valuation figure?
5. Do you top-slice personal income if ICR is tight?

Tenant Type and Business Model

1. Do you lend on student HMOs — and is landlord experience mandatory?
2. Are professional-only HMOs treated differently from student properties?
3. Do you cap the number of student or large HMOs in my portfolio?
4. Will you finance properties with mixed tenant profiles?

Student-specific criteria are covered in our student HMO mortgage guide.

Borrower Profile

1. What income proof do you need for self-employed applicants — two or three years' SA302s?
2. Do you offer contractor day-one products on HMOs?
3. How do you treat limited company directors buying personally vs through an SPV?
4. What is the maximum age at end of term?
5. Do you lend to expats or non-UK residents?

Limited Company and SPV Lending

1. Do you lend to SPVs — and which SIC codes do you require?
2. Is a personal guarantee mandatory for all directors?
3. Is LTV lower for company purchases than personal name?
4. Will you lend to a newly incorporated SPV with no accounts?

See our SPV setup guide for company formation expectations.

Fees, Rates and Product Terms

1. What is the arrangement fee — flat or percentage — and can it be added to the loan?
2. Are there valuation, legal, or administration fees?
3. Is the rate fixed or variable — and what happens after the initial period?
4. Are there early repayment charges (ERCs) — and for how long?
5. Is interest calculated daily — can I overpay without penalty?

Valuation and Survey

1. What survey level do you require — drive-by, physical, or full structural?
2. If the valuation comes in low, can I challenge it — and what evidence do you need?
3. Will the valuer comment on HMO compliance (fire doors, room sizes)?
4. Does a failed compliance note block completion until works are done?

Completion Conditions and Ongoing Rules

1. Must the property be let on completion, or can I complete with a void for refurbishment?
2. Do you offer refurbishment or bridge-to-term products if works are needed?
3. Must I use a regulated letting agent, or can I self-manage?
4. Do I need to notify you if licensing status or occupancy changes?
5. What happens if I remortgage before the initial rate ends — portable products?

Refurbishment options are outlined in our HMO refurbishment finance guide.

Portfolio and Remortgage Strategy

1. How many mortgaged BTL properties can I hold before portfolio rules apply?
2. Will you aggregate debt across my personal and SPV holdings?
3. Do you offer portfolio switches or blanket facilities for multiple HMOs?

Portfolio landlords should review portfolio HMO criteria.

Red Flags in Lender Answers

Walk away or seek alternatives if you hear:

• Vague answers on planning or licensing ("should be fine")
• Willingness to proceed without written HMO licence where required
• Student let described as standard BTL to avoid HMO pricing
• No clear ICR calculation when you ask for worked examples
• Pressure to pay full fees before basic eligibility is confirmed

Specialist HMO brokers document lender responses and match products to your file — reducing mis-sale risk.

How to Use This Checklist in Practice

1. Shortlist three to five lenders (or ask your broker to) based on property type and LTV
2. Run through sections 1–15 before making an offer — these kill most deals
3. Confirm fees and valuation before paying application money
4. Get an agreement in principle (AIP) with explicit HMO assumptions stated
5. Reconfirm at full application if anything changes (purchase price, room count, tenant type)

Keep a spreadsheet of answers. Lender criteria change quarterly; dated notes help at remortgage time.

Frequently Asked Questions

Should I speak to lenders directly or use a broker?

HMO lending is niche. A specialist broker accesses lenders you cannot apply to directly and filters criteria quickly. Direct applications suit experienced investors who already know which two or three lenders fit.

Is an AIP binding for HMO mortgages?

An AIP is indicative, not a guarantee. Full underwriting, valuation, and compliance checks can change the outcome. Treat AIP as a green light to proceed, not a promise.

What is the most important question to ask first?

Whether the lender accepts your specific HMO type (size, licensing, location, tenant profile). Everything else is irrelevant if the property is outside criteria.

Do all HMO lenders require the same ICR?

No. ICR ranges from 125% to 145%+ and stressed rates vary. Two lenders at the same headline rate may offer different maximum loans.

Can I ask the lender to speak to the valuer before survey?

Some brokers request pre-valuation guidance on HMO rent assumptions. You cannot usually contact the valuer directly, but providing comparables through the broker helps.
