How many properties do you need before a lender considers you a portfolio landlord?


The short answer is four or more mortgaged buy-to-let properties.


Under the PRA definition, a portfolio landlord is someone with four or more distinct mortgaged BTL properties. The properties are considered across lenders rather than simply counting the mortgages held with the lender you are approaching.


Once you reach portfolio status, lenders may take a broader view of your property business. Instead of looking solely at the property you are trying to finance, they may consider your existing properties, mortgage balances, rental income across the portfolio, property values, gearing, experience and the overall strength of the portfolio.

An HMO might be a large house converted into several bedrooms, with tenants sharing a kitchen and communal areas. An MUFB might be a house converted into three self-contained flats, or a small block containing several flats under one freehold title.


The difference can affect the type of mortgage available, how the property is valued, how rental income is assessed, planning and building regulation considerations, lender experience requirements and maximum LTV.


Planning classification is also important. In England, small shared houses occupied by three to six unrelated people can fall within C4, while larger HMOs can be sui generis. Local planning restrictions can also apply.


There isn't a universal answer as to which is better. The right structure depends on the property, the investment strategy and the lender market.


At Eastgate, we look at the property as a whole before deciding whether HMO, MUFB or another form of specialist residential finance is most appropriate.

Auction finance vs bridging finance The terms are often used interchangeably, but there is a subtle distinction. Auction finance is generally bridging finance structured specifically around an auction purchase and its completion deadline. Bridging finance itself is much broader. Auction finance is driven by the deadline. You have committed to buy a property and need short-term funding to complete within the auction's contractual timescale.

What happens if a property is unmortgageable? A property being described as 'unmortgageable' doesn't necessarily mean it can't be financed. It usually means that a conventional mortgage lender is unwilling or unable to lend against it in its current condition. There are many reasons: no functioning kitchen or bathroom, significant structural defects, major refurbishment, incomplete works, missing services, planning issues, unusual construction or short-term title problems. The important thing is to understand why the property is unmortgageable.

How quickly can auction finance complete? Auction purchases are often driven by a deadline. That deadline might be 28 days, although the exact requirement depends on the auction contract. Specialist auction finance is designed around this type of time pressure, but there isn't one universal completion time.  A straightforward transaction with a clear property, experienced borrower, suitable valuation and clean legal work can move quickly. A more complex property can take longer.

How does auction finance work? Buying a property at auction is very different from buying through the traditional sales process. Once the hammer falls, you have generally exchanged contracts and become committed to completing in accordance with the auction conditions. That is why finance needs to be considered before you bid, rather than after.

Can you get finance on a licensed HMO? Yes. Having an appropriately licensed HMO can be an important positive when applying for finance, but a licence alone does not guarantee that a lender will accept the property.  The lender will generally want to understand whether the property is being operated in accordance with its planning and licensing position. This can include the current HMO licence, permitted occupants, bedroom sizes, planning use, rental income, property condition and the borrower's experience.

What makes an HMO mortgage application more complex? An HMO mortgage application can be straightforward. It can also become considerably more involved than a standard buy-to-let application. The difference usually comes down to the property itself and how well the finance, planning, licensing and investment strategy fit together.

HMO vs MUFB finance: what's the difference? HMO and MUFB finance are often discussed together, but they are not the same thing. The simplest distinction is this: an HMO is about how a property is occupied; an MUFB is about how the property is divided into separate units. A House in Multiple Occupation is typically occupied by multiple households who share facilities. A Multi-Unit Freehold Block, or MUFB, usually contains two or more self-contained residential units under one freehold title.  That distinction matters to lenders.

What is an HMO Mortgage? An HMO mortgage is a specialist buy-to-let mortgage designed for a property being operated as a House in Multiple Occupation. An HMO is generally a property occupied by people from more than one household who share facilities such as a kitchen or bathroom. In England, a property occupied by five or more people forming two or more households will often fall within mandatory licensing requirements, although local authorities can introduce additional licensing requirements. Planning and licensing are separate considerations, so the position for the specific property needs to be established.
