Looking to get some guides on where or how to start.

By purchasing a multi-unit property, living in one unit, and renting out the others, you can cover your mortgage payments and start building equity while gaining rental income.

I'm passionate about teaching real estate in underserved communities and helping others build wealth through knowledge.Looking Ahead: I’m seeking local and out of state investors, lenders, and professionals in the Atlanta area for STRs and MTRs, and in Birmingham, Phoenix, Columbus, Macon, and Augusta, GA for long-term rentals and small multifamily deals.Let’s connect if you share my vision for creating real estate that not only generates wealth but also builds lasting, positive change.

Funny enough, I was going to suggest you move out of SF due to the high cost ;-) I'd suggest going down the SF condo route to start as financing for commercial units is a lot more difficult than residential properties.

I considered starting out house hacking a MF, but it will only increase my monthly expenses, not lower them or provide cash flow. 

I am planning on doing a flip or a build in Phoenix in the next one to two years.

Just make sure to focus on market selection, financing options, and building a solid team—especially a reliable property manager.

Quote from @Jimmy Sont: I'm looking to build around 700 sq ft 2 bed / 2 bath guest house primarily used for short to mid term rentals.

This is hands down the best and easiest way to get started.

If you've got to ask this question, no, you should not start lending.
