About your mortgage

Error: Yearly income income must be between £1 and £10,000,000.

Error: Regular bonus must be between £1 and £10,000,000.

Based on your yearly income, you may be able to borrow:


Most lenders will let you borrow 4.5 times your annual salary so, as long as you have a standard 10% deposit, you should be able to borrow this much.


Depending on your personal circumstances, some lenders may let you borrow 5 times your salary.


Lenders usually cap the amount they lend at 5.5 times your salary, so it’s unlikely you’ll be able to borrow more than this.

This calculator is an estimation of how much you could borrow. If you’re ready to take out a mortgage, speak to a Revolution brokers to see what options are available.

Construction Mortgages on Single Brick Properties

Single skin or single brick properties are built from a single bricklayer on the outer wall - most commonly found in Victorian homes.

Revolution Brokers often receive inquiries about this type of mortgage, since a single brick property is considered non-standard and will fall outside of many high street mortgage lenders' policies.

There are, however, plenty of alternative options, which we will explore in this guide. For more assistance with securing a single brick property mortgage, give us a call on 0330 304 3040, or email the team at

Is it Hard to Mortgage a Single Brick Property?

It can be a little more complicated, but by no means impossible.

Older homes can be single brick constructions, whereas developers will always build a new-build to modern construction standards. The problems for a lender include:

  • The potential instability of a single brick outer wall.
  • Lack of energy-efficiency.
  • Issues with soundproofing, condensation and damp.

Mortgages for two-storey properties built entirely from single brick are rare indeed, but we also hear from clients who have been rejected due to any one area of a wall being constructed in this way.

Does it Matter what Type of Single Brick Construction I am Buying for Mortgage Application Purposes?

Yes; there are lots of different types of single brick properties:

  • Single brick or single-skin construction mortgages.
  • Mortgages for extensions made from single bricklayers.
  • Properties with one wall that is single skin brick.
  • Breezeblock single skin construction mortgages.

If you are unsure which category your property falls into, do get in touch and we'll help you identify the right lender to apply to.

What are the Eligibility Rules About Single Brick Property Mortgages?

The issue with any non-standard property is that it is perceived as a higher risk by the lender, impacting the potential resale value.

In these cases, some lenders will set a limit, so for example, they might refuse to mortgage any home over one-quarter single brick walls. The other criteria depend on your circumstances - so if any of these are also higher risk, the number of lenders you can apply to is reduced:

  • Credit rating - the better your credit record, the lower the risk.
  • Income - lenders prefer PAYE employment since it is lower risk, but you can find self-employed mortgages and lending for variable income applicants.
  • Age - later life mortgages can be trickier to come by, although you can apply to specialist lenders who don't put an age cap on their lending.
  • Outgoings - pre-existing debts and hefty outgoings are also calculated as part of the affordability assessment.
