Here are some software for the property managers.
Most PM firms you can find which use a big-brand software will actually highlight their use of such software as a significant value-add to their business which they use to differentiate themselves from their competition. And with good reason – the software does a lot. While AppFolio only costs $1 per month per unit, it has a $200/month minimum. Buildium has a nice app support, web portal for owners and tenants, the lower cost for small real estate portfolios, pretty close feature parity with AppFolio or PropertyWare too.
Some shortlisted, basic features – rent collection (ACH or cash), basic accounting, work order, vendor payments, tax forms etc.)
