My recommendation is none of the above.

@Simon Packman - This year I got insurance for a quadplex through Steadily Insurance (Broker) that I've been happy with, so I would recommend giving them a call.

I told her this simple fact and stated, "unfortunately I would recommend calling a locksmith." 

My realtor recommended SDIRA Wealth, a company known for its high-volume new builds every year.

I'm eager to learn more about:Identifying undervalued properties: Are there any specific strategies or resources you recommend for finding deals below market value?

I also recommend you talk to Section 8 about handling problematic Section 8 renters.

If you can find an investment that pays for itself, you won't be so nervous about investing.I also recommend you educate yourself on how to manage well.

The squeaky wheel wins in development so I'd recommend you staying on all communication with the city so that you can see the communication and push as the owner.

I'd recommend having enough to close on the deal + rehab + $5k in reserve as a minimum. 

I know you want to go full time and jump in, but I'd recommend staying with your day job as long as you can - it makes your life a lot more comfortable to have a steady stream of income to pay the bills every month!
