I created BrightInvestor and would be happy to chat about how we go beyond just market research but also help you find the properties well - with free owner phone numbers and sales comps. 

I've been looking at single family home prices and rental prices in Austin TX and its suburban areas, and it feels like it's extremely unrealistic to find something that passes the 2% rule.

You might be best fit finding those in between deals. 

Cash is king when it comes to buying homes in the wholesale market, and this rule also applies to many other scenarios.

Your best course of action is going to be to really see what you can do to get your credit score up as quickly and as much as possible - you will likely be able to find options right now - but your terms are going to be much much better if you can get that credit score even up like 30-40 points

Additionally, are there micro-markets that may offer less cash flow, but more consistent and dependable tenants, rental payments, etc.?  

Where can I find a lender?

You can find the agenda-at-a-glance HERE.

If I invest a multifamily through a Roth IRA, will I still receive the same tax benefits as I would with personal cash when I file my tax return?

Rates have now decreased from averages in the mid-7's to now upper-5's, yet the market has not seen a "speed up" -- likely due to the seasonal swing, and the upcoming election. 2025 should see strong property value growth, with increased inventory, but also increased buyer activity with rates expected to continue downward.
