I am looking into the possibility of selling it through subto. 

I say take a gamble for anyone in which its even possibly feasible for and trust they're process. 

So outside of licensed electrician, plumber etc I ended up doing as much as possible myself, 5 hours every workday night and sun up to sun down on weekends.Looking back this was a huge adventure for me personally, it took me 2 years, I learned a lot and it made me a better investor.

I'm a broker in CA and that's just not possible, especially when you completed your due diligence in 10 and wanted to cancel escrow. 

who say deregulation is possible.

I appreciate you hitting on all the potential possibilities in detail. 

Does not need to be perfectly soundproof but if it as bad as you allude to then you need to deal with it as soon as possible.

-The mention of syndication being less risky than HML...I'd suggest it is more risk, possibly much much more since you don't know whether you are good or bad at vetting the operator right now.

I’m just getting started and looking to soak up as much knowledge as possible—whether it’s about finding good deals, managing renovations, or understanding the financial side of things. 

Your time is best spent producing the revenue that allows you to invest in the first place.That includes using local agents you meet and feel are a good fit for you, property managers, possibly buying completed properties like the one you posted here, and outsourcing as much of the process as you can as you get started.
