Make sure you understand the basic math, what qualifies as a good investment, how to manage your investment and prevent losses, etc.I would start with Set For Life by Scott Trench.

This is actually something I see as a benefit because it shows that the city is interested in facilitating the growth of that industry, and it's much less likely now that they would do a 180 and try to limit usage

I think the person in the mirror has reached the top of the knowledge limit and needs someone that is an expert to move me to a higher level. 

A stock market loss of 30% is a crash.

I just got off the phone with the HOA and they've reached their allowed limit for LTRs so it's looking like a flip deal.

I am somewhat limited with time but have right mindset.

Many lenders include a prepayment penalty  that lasts 3-5 years, which could limit your ability to refinance again if rates drop in the future. 

For me personally I will stay out of the city limits for STRs.

Not sure is selling individually is worth the headaches or count my losses and sell as a whole, if there is any? 

In areas like South DFW, challenges like limited inventory and high prices require creative approaches such as off-market deals, foreclosures, or properties needing updates.
