Property with land mortgages: Should you use a bank or building society?

Buying a farmhouse, country house or residential property with several acres of land can make finding the right mortgage more complicated.

A standard-looking house can suddenly fall outside a lender's normal mortgage criteria because it comes with five or ten acres, paddocks, stables, barns, annexes or substantial outbuildings.

Specialist building societies such as Harpenden Building Society can be particularly useful for these cases because they take a more individual approach to underwriting unusual properties. However, that does not necessarily mean borrowers should automatically take a specialist building society mortgage.

Some mainstream banks may also be prepared to mortgage properties with land – and potentially offer much cheaper interest rates and lower arrangement fees.

Can you get a mortgage on a property with land?

Yes. It is possible to get a residential mortgage on a property with land, including homes with substantial gardens, paddocks and outbuildings.

The number of mortgage lenders willing to consider the property can depend on:

• How many acres come with the house

• Whether the land is residential, agricultural or equestrian

• How the land will be used

• Whether there are paddocks or stables

• Whether any land or buildings are commercially let

• The number and type of outbuildings

• Whether there is an annexe or separate accommodation

• Whether any additional accommodation generates rental income

• The condition and construction of the main house

• Whether there are agricultural restrictions

• The property's value and location

• The lender's valuer's opinion of the property and its future saleability

This means two properties with exactly the same amount of land could receive very different responses from mortgage lenders.

Why is Harpenden Building Society good for mortgages on properties with land?

Harpenden Building Society is one of the lenders Trinity Financial's brokers may consider when clients are purchasing unusual rural homes or properties with more complicated characteristics.

One of Harpenden's strengths is its individual approach to mortgage underwriting. The building society says specialist underwriters assess eligible applications individually and consider properties including houses with annexes and mixed-use properties. It also has criteria allowing certain properties with agricultural restrictions, subject to the restriction being satisfied and the valuer's comments. 

Harpenden also works exclusively through mortgage brokers and intermediaries, rather than providing mortgage advice directly to borrowers. It lends on properties across England and Wales. 

That approach can make Harpenden useful where a property does not fit neatly into the automated criteria used by some larger banks.

What types of unusual property will Harpenden consider?

Harpenden's published mortgage criteria demonstrate why it can be useful for more complicated property applications.

Its residential proposition includes houses with annexes, while its specialist lending proposition extends into areas such as barn conversions, land purchases with planning permission and new builds on existing owner-occupied land. 

The Society can also consider properties with agricultural restrictions, subject to the circumstances and valuation. This does not mean every farmhouse or property with acreage will automatically be accepted. The property still needs to provide suitable security for the mortgage and pass the lender's valuation and underwriting process.

Is Harpenden Building Society always the best lender for a property with land?

Not necessarily. Harpenden can be an excellent option when a borrower needs flexible property criteria and manual underwriting, but borrowers should still establish whether another bank or building society can provide a suitable mortgage.

A larger high-street lender may sometimes be willing to accept the property and could potentially offer:

• A lower mortgage rate

• A smaller arrangement fee

• Free or cheaper valuation options

• More competitive large-loan pricing

• Higher overpayment allowances

• Different fixed or tracker mortgage options

Specialist lenders and smaller building societies provide an important service because they will often consider cases that larger banks will not. However, borrowers should not assume that an unusual property automatically requires specialist mortgage pricing.

Bank or building society for a property with land?

The best lender is therefore not simply the bank or building society advertising the lowest mortgage rate.

The first question is whether the lender will accept the property. The second is how competitive its mortgage is once suitability has been established.

Should you shop around for a property with land mortgage?

Yes. 

Shopping around can be particularly important when buying an unusual property because lender criteria vary much more than they do for a conventional house.

Trinity Financial's brokers have built up contacts with more than 20 banks and building societies that may consider properties with land and unusual characteristics.

When a client sends us details of the property, our brokers can quickly approach relevant lenders and ask whether they are prepared to consider it.

This can include homes with:

• Several acres of land

• Paddocks

• Stables

• Barns

• Agricultural buildings

• Large gardens

• Annexes

• Guest accommodation

• Separate apartments

• Multiple outbuildings

• Equestrian facilities

• Period or listed buildings

Rather than submitting a mortgage application to one lender and discovering weeks later that its valuer does not like the property, it can be useful to establish lender appetite at an earlier stage.

Can a bank offer a cheaper property with land mortgage?

Potentially, yes.

A client may initially be told that they need a specialist property mortgage because of the acreage or outbuildings. However, another bank may take a different view.

Trinity Financial recently helped next-time buyers purchasing a £1.4 million farmhouse with approximately 10 acres, paddocks, outbuildings and three separate apartments.

Another broker had proposed a specialist building society. Trinity approached its lender contacts and found a large mainstream bank willing to consider the property.

The clients secured a £950,000 repayment mortgage at 4.85% fixed for two years, over a 30-year term. They chose a two-year fix because they wanted to use the lender's 10% annual overpayment facility to reduce the mortgage balance and reassess mortgage rates when the fixed period ends.

It is a good example of why buyers of unusual rural properties should not assume their first specialist mortgage recommendation is their only option.

Mortgages on houses with 5, 10 or more acres

There is no universal rule stating that a residential property becomes unmortgageable once it exceeds a particular acreage.

Some lenders may be comfortable with a large amount of land if it is essentially part of the residential property and there is no significant commercial activity.

Others may impose much tighter restrictions.

The use of the land can be as important as the number of acres.

For example, ten acres used as private gardens and paddocks may be assessed differently from land producing agricultural income, operating as a commercial livery yard or being subject to agricultural occupancy restrictions.

Mortgages on properties with stables, paddocks and barns

Houses with equestrian facilities can also require additional lender checks.

A lender is likely to want to know whether stables and paddocks are being used privately or as part of a commercial operation.

The same applies to barns and other outbuildings. A garage or storage barn may cause few concerns, while a converted building containing independently let accommodation could substantially change the lender's view.

This is why detailed information about the property should ideally be provided to the mortgage broker at the start.

Mortgage broker for properties with land

Trinity Financial's expert mortgage brokers regularly arrange mortgages for farmhouses, country houses and unusual residential properties with land.

Our brokers can approach mainstream banks, smaller building societies such as Harpenden Building Society, specialist lenders and private banks to establish which lenders are most comfortable with the property.

Aaron Strutt, Product Director at Trinity Financial, says:

“There is often a big difference between mortgage lenders' attitudes towards houses with land. One bank may not want a property with substantial acreage, outbuildings or separate accommodation, while another may be perfectly comfortable with it.

“Smaller building societies such as Harpenden can be very useful because they take an individual approach to more complicated properties. But it is still worth shopping around. If a mainstream bank is happy with the property, borrowers may be able to access a cheaper mortgage rate or pay lower setup fees.

“Over the years our brokers have built up a list of more than 20 lenders we can approach about properties with acreage, paddocks, annexes, stables, barns and substantial outbuildings. This means we can quickly establish which lenders are interested before deciding where to place the mortgage application.”

Buying a property with land? Speak to Trinity Financial

If you are considering buying a house with land, farmhouse, country house, equestrian property or home with paddocks and outbuildings, it can be worth checking your mortgage options before committing to one lender.

The cheapest-looking mortgage is no use if the bank will not accept the property, but equally, borrowers should not automatically pay specialist mortgage rates if a mainstream lender is prepared to help.

Trinity Financial's mortgage brokers can approach more than 20 relevant lenders to establish which banks and building societies may consider the property and compare the available mortgage rates, fees and criteria.
