HMO products offered

Aldermore’s specialist buy-to-let portal takes HMO, limited-company, multi-unit freehold (up to 4 units) and multi-property cases. Purchase and remortgage. The first-time landlord line in the July 2026 guide is a single residential unit — it is not an HMO product.

Who this lender suits / does not suit

Suits a landlord with at least 12 months’ letting who wants a C4-scale HMO of up to six rooms at up to 75% LTV. Limited companies and LLPs sit here. Does not suit a first-time HMO buyer, a 7+ bedroom house, or anyone treating Aldermore’s first-time landlord product as an HMO route.

How to apply through a broker

HMO cases go through the specialist buy-to-let portal, not the residential portal. Send room count, licence status and who has the 12-month letting history. There is no charge for an initial quote.

Next step: quote / speak to a specialist

Tell us the room count and who has 12 months’ letting. We will not send a first-time HMO purchase to Aldermore’s first-time landlord desk.

FAQs

Aldermore HMO Mortgage: Criteria & LTV (2026): published criteria, not a live rate card.

Do you Require No Fee Mortgage or Remortgage Advice?

Aldermore publishes free or assisted legal routes on some remortgages in its July 2026 BTL criteria guide. That is not a promise of a fee-free HMO rate. Arrangement, valuation and broker fees are set on the offer. Ask for a dated illustration.
