New-Build Mortgages for First-Time Buyers:  New-build mortgages can involve stricter LTV limits, developer incentives and fixed reservation deadlines.

The lender values the completed property rather than accepting the developer’s price automatically.

Buyers should coordinate the mortgage offer, legal work and construction timetable.

What Counts as a New-Build Property?

A new-build is usually a property being sold for the first time after construction or conversion.

It may be:

• Complete and ready to occupy
• Still under construction
• Purchased off-plan
• Part of a large development
• A converted commercial building

Lender definitions can vary.

Some lenders apply new-build criteria to recently completed properties even after initial occupation.

Why Can Deposit Requirements Differ?

Some lenders impose lower maximum LTV limits on new-build flats than on houses.

Reasons may include:

• Resale uncertainty
• Development concentration
• Incentives
• Limited comparable sales
• Early price premiums
• Leasehold concerns

A buyer with a 5% deposit may therefore find fewer options for a new-build flat.

Check the likely lender policy before paying a reservation fee.

How Are Developer Incentives Treated?

A developer may offer:

• Deposit contributions
• Cashback
• Legal-fee contributions
• Furniture packages
• Upgrades
• Stamp Duty contributions
• Service-charge payments

These incentives must normally be disclosed.

The lender may reduce the value used for mortgage calculations or limit the permitted incentive.

For example, a property advertised at £300,000 with substantial incentives may not be treated as a straightforward £300,000 purchase.

Tell the adviser and solicitor about every incentive.

What Happens at Valuation?

The mortgage valuation is for the lender.

It considers whether the property provides suitable security.

The valuer may consider:

• Comparable sales
• Location
• Development size
• Construction
• Lease terms
• Ground rent
• Service charges
• Local demand
• Incentives
• Build stage

The valuation can be lower than the agreed purchase price.

The buyer may then need a larger deposit, renegotiation or another property.

Why Do Completion Dates Matter?

Developers often expect exchange within a defined period after reservation.

However, completion may not occur until construction finishes.

This creates several timing questions:

• How long is the mortgage offer valid?
• Can it be extended?
• Will the lender reassess affordability?
• Could the product expire?
• What happens if construction is delayed?
• Is there a long-stop completion date?

A mortgage offer issued too early may expire before the home is ready.

An application made too late may miss the exchange deadline.

What Should the Solicitor Review?

Legal checks may include:

• Planning permission
• Building regulations
• New-home warranty
• Roads and drainage
• Estate charges
• Lease terms
• Ground-rent provisions
• Management company
• Restrictive covenants
• Completion notice
• Snagging rights

The mortgage adviser does not replace the conveyancer.

Each professional examines a different part of the risk.

What Is a New-Home Warranty?

Many lenders expect an acceptable warranty or professional consultant certificate.

The lender decides which warranty providers and certificates it accepts.

Confirm this before exchange.

Finding Relevant Mortgage Support

The Connect Experts residential mortgage page provides access to guidance and adviser searches for home purchases.

When comparing advisers, ask whether they understand:

• New-build LTV limits
• Off-plan purchases
• Developer incentives
• Offer extensions
• Shared ownership new builds
• Leasehold flats
• New-home warranties

A new home may never have been occupied. The mortgage process still carries a history of deadlines, contracts and assumptions that must be examined.
