Multi Family vs SFH Resale?

[Ryan Ford]

I would consider a duplex, 4 plex or other multi-family unit. However, in the chance you decided you wanted to liquidate the asset wouldn't it be much harder to move a multi unit versus a Single Family Home?

I am in this for the long run, but let's say an area starts to become less desirable or  another circumstance out of your control arises. 

I read the ABC's of real estate. It stated there is less risk with a multi-family due to you have say 8 tenants covering rent instead of 1 in a SFH. However, I didn't really see the book address my question. I would appreciate any thoughts. Thanks.
