Apartment vs. SFH rental rates

[James Masotti]

There is an 8 unit building in my area that I've been looking at and am curious to know if there is any difference in the rents I can expect to get for an apartment as opposed to a single family home (which is what I'm used to) 

I'm guessing that the square footage is a bit less...but like a 3/1 SFR in my area probably rents for 1050-1100 the proforma on this says they've got it leased at 700. I can't imagine that they're that far apart even if the apartment is only 900-1000 sqft instead of 1200-1400 like a SFH would be. The same is on the 2/1 units. Market is probably around 800-900 and these are renting for 600

For those folks who have experience with both multi-family and SFR, can you chime in on your thoughts about the rent differences?

Thanks!
