I am about to graduate college in May 2025, and will be making about $120k (pre tax) in my full time job postgrad (Washington DC area).

You’ve got a good system going, to find and get funding for these acquisitions.  

A 50% LTV on a $120K house at 7%, 30 year Am results in a $400/mo interest payment.The cashflow on your existing duplex goes to $1,000 per month, but now you can buy another just like it so yoru cashflow goes to $2,000 per month.  

My advice: don’t overthink it—your first house hack is about learning, so pick a strong rental market, ensure solid demand, and lock in a deal that gets you close to break-even or better.

As for the 5 year annualized, that’s a number we get from the bigger pockets rental analyzer.

Similarly, if you put several Class D tenants in a Class A 4-plex, what do you think will happen to the property?

Nicholas makes a great point—having strong ties to a market definitely helps, and picking a random low-cost market without a network can be tough.

A&M Courtyard Apartments are a fully stabilized 33 unit apartment complex that is comprised of a mix of 1 and 2 bedrooms.

Multifamily real estate has traditionally been a stable asset class, and the Washington D.C. metro has traditionally been a stable market area, making the two together a good safe bet, especially for anyone with a long-term view of their investing strategy.

You can also take a car ride and travel to Dallas, Houston or Austin.I think NYC is a good city if you want to work and make a lot of money.
