and they even have an app.

Have you heard of Rent App and is that a good idea (instead of Venmo) and sufficient for tracking rent payments?

Much depends on what you give the CPA...........is it a shoebox full of paper or did you fill in their app?

I am at the point to where I want to purchase, but I am having trouble with finding commercial or residential property listed the one app I once used does not work any more.

I've been using the underdeveloped app.

We do complete kitchen and bath renovations and re-designs often down to the studs which far exceeds a typical turnover renovation where you'd maybe do minor repairs, paint and lay floor.I think I could probably manage 200+ units using Buildium property management software (or some other full featured app) without breaking a sweat.

What is the average cost for purchase, installation, and the associated app?

IO also is an option if concerned about monthly cash flow. 

Both of those criteria should be searchable to some extent via software/apps like Propstream.

Since I last posted we now have seller lead service, skip tracing, API integration for direct mail and a mobile app for managing your business on the go.
