I know there are inherent differences between these assets and SFH such as mandatory HOA, shared wall(s), no/small yards, but from an investment perspective, are they truly that different? 

I had my handyman do it for 15K and now rented at a higher rate....Another property in Florida, the tenant left such a mess in the house (gum in the carpet, drawing on the walls, etc), and the property management Company (I think their name is Watson) wanted to fully refund the tenant their security deposit! 

While the furniture selection, and a cohesive, clean aesthetic will grab attention, it comes down to murals on walls, plate and dish selection, open shelves versus cabinets in the kitchen.  

Quote from @Jaron Walling: @Joe Baier From my point of view you're buying two problems.

They provide no real protection at all for the borrower/contractor relationship.So, if your house had some plumbing work that was done, and your contractor did not pull permits and they did not have the city inspect the work, then when you go to sell the house you will get caught and they will tell you that they need to open the walls to inspect the plumbing and then closing the walls and repainting are on you.The draw process is way too easy, I've learned that it is sooooo worth paying your personal inspector like $100 to do a deep inspection. 

Virtually all basements are going to have water concerns, whether from high water table, moisture attempting to move from soil to concrete/concrete block to air, actual infiltration from walls, etc.

My digital marketing experience comes primarily from selling physical products such as t-shirts, wall art, family gifts, etc… on Facebook, Google, Etsy.

Other than shared walls, a side-by-side plex offers the feeling of a townhome or apartment where there's a fair amount of privacy (great for families or couples).

Generally you want to stick with what you're good at which is investing and your full time job and find a broker who is good at insurance and understands the investment side of real estate as well.Expanding on my comment further condo insurance is different than a single or multi family home as you are typically insuring the "walls in" of the condo as the association is responsible for the exterior of the building.
