Single family hone versus duplex rent

[James Kim]

Hi,

I was just curious whether rent rates for a duplex are lower than for single family homes if all else was equal. If the duplex had a back yard and covered garage just like a sfh, except you're sharing one wall with the other duplex, would you, as landlord, generally expect rent to be lower than for a sfh?

If so, then how much lower is typical?thanks!
