Do you use a DIY Landlord app/software service? If so, which one?

[John Walter]

There are a lot of services out there that offer a ton of services for DIY landlords (tenant screening, background/credit searches, rent payments, maintenance scheduling), all for no (or a modest) fee. I have heard of Rent Redi, Zillow Rentals, Avail, Cozy, etc. My question is, are any of these services worth it? If so, what would you recommend? Or, avoid all the above and just do it myself?
