I specialize in renting to Section 8 (BRHP) in nicer areas of Baltimore County and noticing significantly deteriorated tenant quality.

There are some solid advantages here: new construction typically means lower maintenance costs upfront, modern amenities that attract quality tenants, and potentially higher rental income.

Recommend you connect & communicate with @Russell Brazil who knows a bit about the Baltimore market.In the meantime, read below about how nightmares often occur:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

I love the federal hill area in Providence, though it tends to be on the expensive side, but also reflects in the quality of tenant and rent that you can get.

I lived in Superior for a while and commuted downtown every day (get satellite radio ha).I'm a realtor, so fortunately I have instant access to what is hitting the market and it's still very hard to find something before 50 other people have found it as soon as it hits the MLS.

That doesn't mean they are wrong, but each place is different, especially with higher-quality hosts and marketing efforts. 

NOI is far superior to what can be found in traditional multifamily.

If you want to scale, particularly if you want to do so quickly, then I recommend you learn how to find a quality PM.

Additionally, I think a new build would attract higher quality renters.

This is a high cost of living area, and in the neighborhood right now, I see a 3 BR of worse finish quality listed for $3k and a 4 BR that's about equal for $3900, both unfurnished with long term leases.
