Mortgage on a Property with High-Rise Construction

A mortgage on a property with high-rise construction is often possible, but it depends heavily on the building’s height, construction method, and safety documentation. High-rise properties are assessed more cautiously by lenders due to valuation, fire safety, and long-term saleability concerns.

This guide explains how lenders view high-rise buildings, what commonly causes restrictions, and when mortgage options may still be available.

---

What is classed as a high-rise property?

Short answer: there is no single definition, but height is a key factor.

Expanded explanation:
Lenders generally consider a property to be high-rise based on:

• Number of storeys
• Overall building height
• Construction method
• Fire safety profile

Buildings above certain height thresholds typically trigger enhanced checks, particularly for flats and apartments.

---

Why do lenders treat high-rise buildings differently?

Lenders focus on risk and resale.

Key concerns include:

• Fire safety and evacuation risk
• Construction materials used
• Maintenance and remediation costs
• Market demand for high-rise flats

If a lender had to repossess and sell the property, they want confidence that demand remains strong and risks are manageable.

---

Does building height affect mortgage approval?

Short answer: yes.

Expanded explanation:
As height increases, lender criteria usually tighten. Some lenders:

• Restrict lending above certain storey counts
• Apply lower maximum loan-to-value ratios
• Require additional safety documentation

Lower-rise apartment blocks are usually assessed more flexibly than taller towers.

---

How does construction type affect lending?

Construction method is critical.

Lenders pay close attention to:

• Traditional versus non-standard construction
• External wall systems
• Presence of cladding or composite materials

High-rise buildings with modern or non-traditional construction may face additional scrutiny, particularly where safety assessments are required.

---

Do high-rise buildings require extra safety documentation?

Often, yes.

Depending on the building, lenders may request:

• Fire risk assessments
• External wall safety confirmation
• Building safety reports

Missing or unclear documentation is a common cause of delays or declined applications.

---

Are all high-rise flats treated the same?

No.

Short answer: context matters.

Expanded explanation:
Lenders consider:

• Location and demand for high-rise living
• Building age and maintenance history
• Reputation of the developer or management company

Well-maintained buildings in high-demand areas are often viewed more favourably than older or poorly managed blocks.

---

Can you get a mortgage without full safety certification?

Short answer: sometimes, but options are limited.

Expanded explanation:
Some lenders may proceed without full certification if:

• The building is below certain height thresholds
• Valuers confirm low risk
• No combustible materials are present

Others require full documentation regardless, which is why lender appetite varies widely.

---

How does high-rise construction affect valuation?

High-rise properties may:

• Be valued more conservatively
• Attract lower maximum loan-to-value limits
• Face reduced lender competition

Valuers assess not just the individual flat, but the building as a whole and its marketability.

---

Is remortgaging easier than buying?

Often, yes.

Short answer: existing lenders may be more flexible.

Expanded explanation:
If a lender already holds the risk and no additional borrowing is requested, remortgaging can be easier than purchasing. New lenders reassess the building from scratch, which can result in tighter criteria.

---

Are specialist lenders an option?

Yes, in some cases.

Specialist lenders may:

• Accept taller buildings
• Take a more flexible view on construction
• Apply higher rates or deposit requirements

These options can help where mainstream lenders decline, though they are not suitable for everyone.

---

What documents do lenders and solicitors usually review?

Expect scrutiny of:

• Valuation reports
• Building safety documentation
• Construction details
• Management company information

Clear and complete documentation helps avoid unnecessary delays.

---

Key points to understand before applying

• Height and construction type are key risk factors
• Safety documentation plays a major role
• Lender appetite varies significantly
• Buying is often harder than remortgaging
• Valuation can affect borrowing even if lending is possible

Understanding how lenders view high-rise buildings early can help avoid wasted applications and unexpected outcomes.
