Brian Davis: My company SparkRental organizes a passive real estate investment club, called the Co-Investing Club.

Look into Baselane it’s designed specifically for real estate investors, You get automated rent collection, expense tracking, it makes it easier to manage properties, stay organized, and keep up with your finances. 

Yup, property condition, vintage, neighborhood, tenant base, property management are all very important considerations. 

Am I correct that a condo, depending on area and neighborhood, could be a lower risk/maintenance investment for an absentee landlord as opposed to other properties?

Make realtor connections to understand what makes each house and neighborhood valuable.  

After closing the golf course in 2018, the parcel was sold to a developer named Westside Investment Partners (WIP) in 2019 who intended to remove the conservation easement and develop this parcel in a highly sought after neighborhood of Denver4.

But this comes with pockets of C/D neighborhoods, and higher potential for headaches;  in addition, appreciation in these zips has probably maxed out for a while.

Quote from @Jules Aton: I started investing in my late 20s during early 90s in up and coming inner city neighborhoods.

In neighborhood it is very important to present your self to the home owner next to you, this helps a lot to prevent misunderstandings. also this shows your professionalism.

I get a good laugh when I read  new investors post about buying C/D neighborhood assets liabilities and announce to the world how well they perform in the first few years focused solely on cash flow.
