Ideally broken down to the city at bare minimum, but even neighborhoods or zip codes would be even better. 

My parents live in a small town in Ohio so I might start there, but at the moment I’m just trying to build connections to find good markets, and from there deals ideally.

You would be leveraging more which doesn't seem ideal for you. 

I save up every 3-5 years to buy 1 property 1.25x DSCRd, ideally through BRRR, and buy about 20% of my downpayment worth in a high-rate not fund--high rate as in a 2-5% above prime but not this egregious triple prime super high risk nonsense).

One of the key benefits of a DSCR loan is that it allows you to qualify based on the rental income the property is expected to generate, making it ideal for those with multiple properties or who may not have a strong personal financial profile or W2.

If you can live for free and only pay utilities AND buy an investment property, that would be ideal in terms of savings and cash flow.If you can't stay and your parents want to make some money on that property, then yes, house hacking would be your best option especially since you don't want the best place in the multi.

Ideally AI could improve the property analytics that shape listing prices, a competitive advantage over other brokers.

City Wide property mgt is who I deal with and honestly when I ask for real numbers and updates I get a lot of BS run around sales talk speech. 

Most of my clients run their SFRs at a 25%-30% (excluding vacancy/credit loss) operating expense margin and most of the banks I deal with on their DSCR loans underwrite using 35%.

A roofer’s invoice should ideally include more details, like the shingle brand, model, and batch numbers, along with a clear scope of work (e.g., tear-off, underlayment, flashing).
