Yeah nothing to show but a successful real estate portfolio, partially funded by a software engineering career that lets me glue django and twilio together to roll my own spam tool in a weekend, if I wanted to.

Recommend you get with your engineering firm and tell them what you want. 

We’re both engineers.

Long story short, they recommend a process that basically looks like...Soil scientist --> (septic engineer IF needed) --> site plan --> county approval...We've spoken to a few soil scientists and they all quote 2k-5k to analyze the property for an appropriately sized septic system. 

I’m a few years out of college and working as a software engineer in Indianapolis.

I give them Engineering report For any structure changes.

I agree with the previous comments about figuring out what your goals are in the next 10 years and reverse engineer - what do you need to do to achieve this? 

An additional benefit of a detailed engineering-based Cost Segregation Study is that it can increase potential insurance premium savings as well as provide support for the property tax appeals process.

I explained I'm a network engineer & am pretty familiar with licensing fees & the open source (aka FREE) options that are available. 

One of the biggest takeaways from my Master's Program in Engineering that has made a huge impact is this: Great solutions come from great problems - you can't find the solution without first understanding the problem.
