. - What systems/software do you recommend to use to determine the markets to invest/buy into?

Referencing another recent post, there's not a great software solution that I am aware of for on-boarding a new MTR resident.If you aren't already, I would make sure you disclose to a potential resident any relevant issues that are endemic to a unit as early as possible.

We add the tenant to our management software to streamline communication throughout the lease duration.

I would recommend you really take your time selecting the right software.

Just a FYI be prepared for it to sell at a discount,Jay- I have seen people buying land notes for 12%-15% yield which is CRAZY and they are going to eventually lose their shirt once they go into default and the land value is repriced.Thank you for the info.

I think I would only move 3 of them to software management at first, see how that goes.

There is no special discount for investors , flippers or landlords .

Then we see if the current tenant later decides to extend or we list the limited open period, often at a slightly discounted rate. 

Software is a common question on BiggerPockets.

You can keep track of which expense goes to which property through your accounting software (even a spreadsheet would work).
