Market Rents for small multis vs apartments

[Chance Johnson]

Hello,

When doing preliminary market rent research using a site like padmapper, how does one modify the most commonly found listings from aparment complexes to better fit a du-/tri-/four-plex? Complexes have pools and other facilities that are included in the rent, as well as other things I'm sure, so I would expect that their rent rates for a 1000 sq.ft. 2-2 would be higher than a similar small multi. So if 5/6 hits from the mile surrounding a property are from large complexes and have rents that range from $950-1200, how much lower should I consider possible rents for a property I am looking at?

Once I decide if it makes any sense at all, I would likely drive around and do a more thorough market rent survey; this is just to see if there is any point, I suppose.
