I do not plan to live in any of my units - I have a family, dog, house that makes that option very undesirable to me.

I’ve been looking into getting some rentals but the more I look into them the more I feel I’ll get myself into dealing with undesirable things.

Taking shortcuts or leaving it to others to "figure it out" usually leads to undesirable results.

You might find available services don't meet your needs, or have undesirable terms.

We have our fair share of undesirables, but you can usually weed them out with proper screening!

I also think there may be some value in creative solutions for undesirable lots / houses that are not maximimizing their zoning potential / building higher end properties / or getting a head start in an under appreciated neighborhood. 

I have given a few agents calls, but it seems difficult to weed out those undesirable characteristics over a phone conversation.

The wifi would also have to be installed in the basement, which can only be accessed through one of the tenants units, so wifi is also undesirable. 

Seriously, grime and dust and dirt can make a place feel pretty undesirable - you don't even always notice it when it's there, but you will notice it when it's gone because the place will just look, feel, and smell nicer.- On that same note, one of the other most important things is also to make the place feel light and bright.

If the area is in a geographically undesireable area or blighted neighborhood that is slowly declining which many communities in the Country are it may not be a very good investment.
