## Mortgage Overview: How HMO Mortgages Work
An HMO mortgage is a type of **buy-to-let mortgage** tailored for properties rented to multiple unrelated tenants who share facilities like kitchens or bathrooms.

## FAQs
### What deposit do I need for best HMO mortgage lenders UK?
Most HMO mortgage lenders require a **minimum 25% deposit**, though some may ask for 30% or more for larger or more complex HMOs. The deposit size can also depend on whether you’re applying as an individual or via a limited company. A higher deposit may unlock better **interest rates** and improve your chances of approval. Always factor in additional costs like fees, legal expenses, and potential refurbishment costs.
### Can I get best HMO mortgage lenders UK through a limited company?
Yes, many of the best HMO mortgage lenders UK offer products for **limited company** borrowers, especially SPVs (Special Purpose Vehicles). This structure offers tax advantages, including full mortgage interest relief, and is increasingly popular post-Section 24.

### What rental coverage do lenders require?
Lenders assess **rental coverage** using a stress test, typically requiring the rental income to cover 125%–145% of the mortgage payment at a notional interest rate (usually 5.5%–6.5%). For limited company applications, some lenders use a lower stress rate, improving affordability. Accurate rental projections and professional letting agent appraisals can strengthen your application.
### How does Section 24 tax affect buy-to-let mortgages?
**Section 24** phased out mortgage interest relief for individual landlords, meaning you can no longer deduct mortgage interest from rental income before calculating tax. This can significantly reduce net profits and impact affordability. Many landlords have switched to **limited company** structures to mitigate this, as companies can still deduct interest as a business expense.

No, HMO mortgages are strictly for **investment properties**. You cannot reside in the property, even in one room, as this would breach the terms of the mortgage. If you intend to live in the property, you’ll need a different mortgage type, such as a **residential mortgage** or **multi-unit residential loan**, depending on the setup.
