If you get a chance tour a 3D printed home .. 100-home community is in Georgetown’s Wolf Ranch and ICON is using its giant Vulcan robot 3D printer to build it. 

It's basically a robot. 

I am a 27-year-old living in Houston, Texas, working for an Energy Company Building RPA Automations (Digital Robots).

You don't want to sound like a robot, but it's a good starting point so you're not saying "uhh" or have awkward pauses on the phone.Here are a few points I'd emphasize:Start by asking the seller if this is a good time to talk after a brief introduction. 

I am a former NASA robotics scientist, degreed in Applied mathematics, Aerospace Engineering, Mechanical engineering, (and a few other degrees not relevant in this case). this doesn't mean that I am automatically right and you are wrong.

If I lived like a boring robot living on rice and beans, I would be able to buy ONE property a year and reach a 10 property goal by the time I was 35, which I thought would be my freedom number.

@David Ramirez talked about SMS and Coldcalling costs, I will chime in with direct mailing.Cost per mailer can range anywhere between $0.40 to $1.50 per letter depending on where you buy from and how customized it is (IE Robot handwritten vs computer text, yellow mail vs designed envelope).

When a fall is detected, every caregiver is alerted along with the resident name and their exact location so they can receive immediate care and assistance.Deply other technology that detects wetness/soiling and provide conveniences with communications (internet/tv) to the highest levels availableWe allow personal animals in our communities, to the point that if a resident would like a pet, we'll provide a robotic pet. 

The priority of the people or robots handling special assets for lending institutions is usually not obtaining the highest price possible - its obtaining a price ACCEPTABLE to the banks board (as total for the assets being sold that fiscal quarter) and the ease of accomplishing the sale.  

Try perhaps rewording your texts to be more human like and less robotic/scripted.
