For out-of-state networking, I'd focus on engaging regularly in BP forums (like you're doing now), joining virtual meetups in your target markets, and connecting with active BP members who consistently provide value here. 

In the past, the Department of HUD targeted S8 rents to be at the lower end of a rental market.

Here’s our OPINION for the Metro Detroit market (use as a template for your target area!)

There are a few dozen houses with my target number of beds/baths/sqft that have been listed for rent on Zillow for 2+ months with 0 applicants.Is this normal or is it a sign that's there's not enough demand for rentals?

A duplex in the $100-200k range with a target CoC return of 8-12% is definitely within reach, especially in some of the emerging neighborhoods.In terms of areas, you might want to explore neighborhoods like Bagley, East English Village, and parts of Grandmont-Rosedale.

Take a look at this ad, which is clearly targeting a keyword that a buyer would use.I know what you’re thinking: “Yeah, I only pay when someone clicks on my ad,” which is true.

I wouldn't move forward with that being your only target for a sale. 

We use tools such as these (any manufacturer/brand) and a mallet to pound them into fully locking.

To use the BRRRR method, target 2-4 unit properties, look for emerging neighborhoods, network with local contractors, factor in property taxes, and work with an investor-friendly agent.Good luck!

Target free and clear properties and market to them through whatever strategy works best for you.
