EP 051: How Interest Rate Rises Affect Your Borrowing Capacity With Aaron Whybrow

I had a call with my Buyers agent a few weeks ago.

He made a passing comment that probably wasn’t significant to him.
But… did keep me up that night.

“If you are thinking of buying another property, move quickly! As you won’t get the lending you want from the bank if you wait too long.”

I pulled him up and asked him to explain.

As I thought that I was in a strong lending position.

My balance sheet and business profits are solid in my eyes.
Even better than last year.

“Interest rates plus inflation,” he said the reason was.

He then went on to school me on how things are changing when it comes to borrowing.

I’ll summarise his points below.

*** Please note the below points were specific to my situation ***
You need to speak to a lending specialist to understand the impacts on your own borrowing capacity.

In the bank’s eyes, your cost of living has gone up due to inflation.

Even if you haven’t changed the way you live, the cost of living for you has gone up, and you are seen as less capable of servicing a loan because of it.

Interest rates:
For every 1% the interest rate goes up, my borrowing capacity will go down 9%

This compounds across all your borrowing, not just the new borrowing you are contemplating.

For someone with a portfolio of my size, a 1% rise can be a 20%-25% decrease in borrowing power.

Pair these up, and my borrowing capacity is being constricted more and more each month!

This is what was keeping me up at night.
I was severely underestimating the impacts of rate rises and inflation on overall borrowing.

So a question I kept coming back to:
“Do I make a move now or wait?”

A tough question for anyone, especially with all that is going on in the world…
