Class b vs Class c rentals

[Enrique H.]

Hi All,

I am looking to expand my rental portfolio  but I am not sure if I should try a b class ( 95k ) sfr, all my rentals ( I have 6 are in a (c class) in eagledale) 

eagledale rentals rent for $750 month paid on  average 55k build in the 1950s

possible buy is on Zip code 46237  for sale for 99k  market value is 120k.  rented now for $950 month, could maybe increase rent to $1050  ( this one is build in the 1980s)

my question is , should I just buy 2 more in eagledale or go for this b class sf?

note: my eagledale homes tent to have issues with plumbing  being too old. so maintenance is more expensive?

Thank you
