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. 

A contractor who left before finishing the completion list, lied on major electrical work that wasn't done correctly or up to code, water leaks everywhere.. and just an expensive list of repairs.

Have you checked with the local authorities on any outstanding code violations?

For New Castle County mostly interested in the zip code breakdown, as in your second and third pictures. 

Pure hustle.....you're mailing, calling, knocking doors....talking to people...... lots of investors for example start with pre-foreclosures, tax delinquent lists, code violation lists, divorce lists, probate lists, etc.

Make sure you pull permits and meet codes. 

My first stop is almost always City-Data.com, which has exhaustive reports on most zip codes and neighborhoods in the US.
