A converted chapel, a former school or a house with extensive grounds may offer exactly what a buyer has been searching for.

Its individuality may be the reason they want it. But the same features can make a lender’s assessment more complicated.

That does not necessarily mean the property is unsuitable security. It means that understanding its value, use and potential resale market may require more than a standard set of questions.

Buyers and lenders look at individuality differently

A buyer may value a dramatic living space, an isolated setting or a collection of outbuildings with endless possibilities.

The lender needs to consider how those features affect demand beyond that particular buyer.

Would the property appeal to a reasonably broad market? How easily could it be sold? Would another purchaser be able to obtain a mortgage on it?

These questions matter because the property provides security for the loan. The lender must assess it with a future sale in mind, even where the buyer intends to stay for decades.

A feature can therefore be highly desirable to one purchaser while still requiring careful consideration from the lender.

The challenge is often the combination of features

Many individual features are manageable.

A converted building may be acceptable. So may private drainage, a large plot or a rural location. But a remote conversion with extensive land, several outbuildings and very few comparable sales presents a more complicated picture.

Lending criteria cannot always be considered separately. A lender may accept each feature in principle but be less comfortable when they appear together.

This is why asking whether a lender “accepts converted churches” or “allows acreage” may only answer part of the question.

The complete property needs to be understood.

An agreed price does not settle the valuation

For a conventional house, the valuer may be able to draw on several recent sales of similar homes nearby.

An unusual property may offer much less direct evidence. Neighbouring houses might differ substantially in size, design, condition, land or use.

The valuer must decide which comparisons are meaningful and how much weight to give the features that make the property distinctive.

The agreed purchase price is relevant, but it does not guarantee the value the lender will adopt. Nor does the cost of creating or restoring a unique home necessarily translate into the same amount of market value.

An appropriate valuation, supported by relevant evidence, can therefore be central to the mortgage application.

How the property will be used matters

A property described as a home may contain much more than the main living accommodation.

There could be a separate annexe, holiday accommodation, a workshop, offices or land used for agricultural purposes.

The lender will need to understand what those areas are used for now and what the buyer intends to do with them. An annexe for a family member can raise different questions from accommodation let separately to paying tenants.

Similarly, a substantial outbuilding used for domestic storage presents a different proposition from one occupied by a trading business.

Depending on the circumstances, the proposed use may affect whether residential, buy-to-let or semi-commercial finance is appropriate.

These details need to be established before choosing the mortgage, particularly where income from part of the property is central to the buyer’s plans.

The legal detail can be as important as the building

Sometimes the main challenge sits in the paperwork.

Access arrangements, title restrictions, planning history and the relationship between different parts of the property can all affect its acceptability.

A buyer might assume that an outbuilding can become accommodation, that an annexe can be let independently or that part of the land can later be sold. Those plans need to be checked against the legal position and the lender’s requirements.

Where a purchase involves a title split or changes to the land included in the mortgage, the lender also needs a clear understanding of the security it will ultimately hold.

These details are best explored while there is still time to address them, with the mortgage assessment and legal work proceeding on the same understanding of the transaction.

The right lender needs the full picture

Some lenders have little flexibility beyond their published property criteria. Others can consider an individual proposition in greater depth.

Specialist building societies and, for suitable clients, private banks may offer scope for a more tailored assessment. That still requires a property they are comfortable accepting, supported by appropriate valuation and legal evidence.

An experienced mortgage adviser can help bring those elements together early, using the particulars, photographs, floorplans, intended use and known complications to seek an informed initial view from suitable lenders.

The value of that work is often in identifying the right questions before money is spent on an application. It cannot remove the need for valuation and legal checks, but it can reveal whether there is a realistic route forward and what needs further investigation.

An unusual home does not always need an unusual mortgage. It does need the right assessment.
