Finding a SFH deal - tool recommendation

[Keetaek Hong]

Other than Mashvisor, are there any other tools that can automatically filter out any new MLS listing based on my criteria (e.g rent avg, cap rate, expense)? And notify me ?
My current flow is 

1) find a house that matches the configuration (X beds, Y bath)  in a certain neighborhood (Redfin or my agent)

2) pull up rent data in rentometer / Zillow 

3) run through my spreadsheet with expenses, taxes, insurances and etc 

I would love these to be automated. Any recommendations ??
