Question 1

What does porting a mortgage mean?

Accepted Answer

**Porting** means transferring your existing mortgage deal — the rate and its terms — to a new property when you move, rather than repaying it and taking a new one.

**Why anyone would want to.** Two reasons:

**Keeping a good rate.** If you fixed when rates were lower, porting preserves that rate rather than moving to current pricing. This can be worth a great deal.

**Avoiding early repayment charges (ERCs)**, which can run to several percent of the balance during a fixed period.

**The critical misunderstanding: porting is not a right, and it is not automatic.** Mortgages are described as "portable" and people assume this means guaranteed. It does not.

Porting requires a **full new mortgage application** on the new property. The lender reassesses:

**Affordability**, against **current** criteria — which may have tightened since, and which is where most porting fails. Income changes, new credit commitments, becoming self-employed, or a child having arrived can all mean you no longer qualify for a loan you already have.

**The property**, which must be acceptable security. Non-standard construction, a short lease or cladding issues can block it.

**Credit status**, reassessed.

A lender declining means you lose the rate **and** pay the ERC, which is a genuinely bad outcome and catches people out.

**How the mechanics work:**

**Borrowing the same amount** — straightforward port.

**Borrowing more** — the additional sum is typically a **second product at current rates**, so you end up with two parts on different rates and possibly different end dates. This is normal and complicates future remortgaging.

**Borrowing less** — you may face an ERC on the portion repaid.

**Timing matters.** Most lenders require sale and purchase to complete simultaneously, or within a short window — commonly 30 days, sometimes up to six months — with the ERC refunded if you complete within it.

**Check before committing** to a purchase, not after.

Question 2

Is a mortgage in principle a guarantee that you'll get the loan?

Accepted Answer

No. A mortgage in principle — also called an agreement in principle, decision in principle, or AIP/DIP — is an indication of what a lender might be willing to lend based on information you have

Question 3

How does a buy-to-let mortgage work, and how is rental income taxed?

Accepted Answer

A buy-to-let mortgage is assessed mainly on the rent the property will produce, not on your income — and the tax treatment changed fundamentally in a way that made highly geared personal ownership

Question 4

What does the mortgage application process involve from start to finish?

Accepted Answer

The mortgage application process involves pre-approval, choosing a lender, completing the application, submitting documentation, underwriting, loan approval, and closing. Understanding these steps is crucial for securing financing.

Question 5

How do I improve my chances of getting approved for a mortgage?

Accepted Answer

To improve mortgage approval chances, check your credit score, reduce debt, save for a larger down payment, maintain stable employment, and compare lenders.

Question 6

What does a mortgage broker do, and how are they paid?

Accepted Answer

A broker assesses your circumstances, searches lenders, recommends a product and manages the application. How they are paid determines whose interests the advice serves, which is the question worth

Question 7

What is negative equity?

Accepted Answer

Negative equity is owing more on your mortgage than the property is worth. If you owe £250,000 and the home would sell for £220,000, you are £30,000 in negative equity. How it happens. Two things
