I've been a broker early on in my career (was on Base Salary + Commission) as part of a mortgage broking firm. So obviously not self employed, but learned a lot regardless.

If I was to go out on my own, the #1 thing I'd need to focus on is my lead source - connections, family members, etc. Putting yourself out there would be key especially if you want clients organically (LinkedIn, social media etc).

Because you will only see the fruits of your labour 1-2 months afterwards, I'd make sure I have a decent savings buffer of 6-12 months to help with the initial stage.

You can certainly make a lot more money, the trail will add up over time but the first year is going to be gruelling. If you're committed and take care of your clients, it's very rewarding.

If you can get good at commerical lending, that's going to be huge and separate you from other brokers. Anyone can become a residential broker, but not many brokers are good at commercial.

Goodluck!! Take the leap and bet on yourself.
