I am currently cleaning up the land and trailers 1 by 1, meeting with City Code enforcer to see what he would like me to fix to get on their good side What was the outcome?

This is question for a local plumber, maybe a commercial one who will know the technical stuff and also what the code says about a single water heater serving multiple units. 

The City of Austin is currently in the midst of a complete overhaul of its outdated land use and development code in an attempt to address some of these issues.According to Austin MLS data, the median price of a single-family home in Austin increased 68% over the past decade.

However we'll typically draw our rectangle/shape/whatever around the area we're covering, or pick specific zip codes, checkmark combined LTV 0-50% (sometime include unknown if small enough area), last mortgage opened 7+yrs and/or lived in the home 10+yrs. 

Environmental science isn’t one of them.Your best options are likely: software engineering, petroleum or electrical engineering.If you dislike coding, I recommend electrical engineering.

That said, check your state codes to see if you will actually need a professional stamp for the work you are doing.

I'm 24 and this is a big lesson that I've learned in life.If you can invest in education that can return a high paying job, for example, a coding bootcamp for $10,000 and become a developer for $90,000/year salary.

I just searched on my phone for the actual city code and couldn’t find it.

PPC has been driving traffic to my site, but after spending $500 on ppc in the last 2 weeks, I have only gotten 2 leads, one which is a mobile home in a rural area (unqualified), and one which is in a suburban area with code violations, but after trying to call them twice, I have not heard from them at all.
