Based on the info provided I would recommend you first start speaking with brokers.

I would make close to 50% ROI, which doesnt make any sense and will never happen here in the Bay Area.Plus, my lowball offer (based on the 70% rule) will just be laughed at. lol.

One such similar examplehttps://www.publicspendforum.net/blogs/steven-kopr...Ummmm...not only are you factually wrong (people have been sent to prison for fires that resulted in deaths where customers emailed the owners about hazardous conditions...they were convicted based on EMAILS) you either didn't read that well or didn't understand it.

Based upon this I would look at an actual dollar amount, not percentage that: 1) enables you to live in a safe neighborhood and decent schools district, is modest in size and fixtures, and has payments sufficiently small that you are still able to invest at least 10-20% (or whatever your target is) of your income. 

The code violations are based on the property being left vacant with no upkeep, making it a public "nuisance" to the neighborhood. 

I guess a good CPA will be able to help me crunch numbers before sale to determine whether I can do a 1031 and if I even should based on investment plans.Would you all recommend I find a good CPA in California near the property (Silicon Valley area) or would a local Texas CPA near where I live now suffice?

But not every neighborhood is right for you based on the questions above.

Anytime you take money from investors and the returns are made based primarily on your efforts, then you are selling a security and need to comply with securities laws.  

@Trent Parker, reach out to @Natalie Kolodij she is based in Seattle area.

I’d do a heat pump systemNo matter what fuel you choose today you could have a compelling reason to regret that decision at some point in the future based solely on price.
