Primary property to rental Owings Mills- please vet my plan

[Priyal B.]

I am planning to buy a townhome, which eventually plan is to rent out, I would like from here if anyone has any idea on owings mills (dolfield/lakeside/near 795), or catonsville (by 695/US 40) market for 3/2.  It is possible that it will produce less cashflow in comparison to other plexes. But I would prefer some appreciation as well.  Planning to stay under 230K, and hopefully it can be rented for 1.8K+ after a while I decide to move out after probably a year+.

Please let me know if any do/don'ts or suggestions.

Thanks!
