I plan on mostly working part-time in Real Estate since I am currently holding down a full-time job as a software developer. 

I am in software so used twilio and a script I wrote. 

If somebody has no skin in the game, it's easy for them to continue their search then leave you hanging at the last minute.Our checks are handled within our PM software so unfortunately, I have no familiarity with Zillow's service.

I'm sure you can find good recommendations for software on here or wholesaling FB groups.

Unfortunatley, it won't get you very far, if your credit report is very short; in other words it lacks data about your financial behaviour, which let's the software calculate your score, which represents your predictability and trustworthyness as a borrower.

And the Software company owner became a long time major client of mine. 

I am a software engineer looking to invest $30-50k in real estate.

I do software engineering by day but I am interested in REI. 

There are software solutions available for Landlords.

I understand that there is landlord software available on the web, but $40/month for software would not make sense, seeing that I only own one property.
