It's a tough ask for software productivity tools when the "spec" (or "problem statement") isn't well defined. 

For example, maybe you make a deal with other providers to sell gift certificates for their businesses at a small discount to help them gain business.

You can use software, get a contractor, or learn it yourself. 

So appreciation discounts. - There are fourplexes with better number if you go out of Austin.

If you are looking for a discount listing agent, I can point you toward many.

Thank you all for sharing current experiences/input about Avail Landlord software. 

Software takes care of the rest. 

Even just doing one of those is hard enough, but now you have to be an expert in finding discounted properties, rehabbing properties, rental and property management, maintenance, and raising capital and getting loans.

My point being what is so much is dependent on the age of the homes, what they are worth on the open at a fire sale discount and what are they worth to you? 

Collateralize it for the down payment of a discounted buy in OK / TX.
