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.

The quality of modern lumber is simply far inferior to the quality of lumber they were using to build homes in the early and mid-20th century.

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

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.

2) They get busy dealing with all the mundane day-to-day stresses and business responsibilities at which time quality, responsiveness and service may, or may not, suffer.3) Sometimes... 

This helps in setting the right rental prices, finding quality tenants quickly, and understanding local laws.

Are their listings detailed with good quality photos?
