Remember, the COE is intended to apply "all the time" and be an overarching moral compass.... remember, many more "hard core" investors do NOT become realtors for this reason (and I THINK the same reason for commercial agents/brokers).Good luck.

I am a hardcore DIY'er when it comes to home renovations and repair.

Beyond that, he should forget about ever seeing anything in the past and hold a hard core line going forward and file to evict as soon as rent is late, or for any other violation in the lease for which he can evict.

House hacking is about learning much more than it is about hardcore penny-pinching (it's still about that, though). 

Im looking for light rehab type properties, im not a hard core flipper 

@Tony Spencer,I'm an omni-vert, and my husband is a hardcore introvert.   

In a week's time, I had:2 great Section 8 tenants renew leases and choose a 2 year lease A house with significant smoke damage from smoldering incense sitting too close to a fake plant (tenant thought she fully extinguished it before leaving but obviously didn't)2 tenants notify us they'll be late on rent this month 1 tenant with a trampoline not responding to our request to remove it A Section 8 property approved for a $50 a month increase at lease renewal A Section 8 bi-annual inspection passed A newly discovered foundation crack at a property I bought 2 yearsI'm a hardcore process & systems person, so we'll handle everything through our processes and keep moving forward. 

Though is not that hard on RE to be honest, (  you could go hard core with stuff) but in reality , just dominating as few formulas , will get you by  and you can always double check them with people that have more dominion on the topic.. try to meet more local investors, and humble yourself like you are doing now, and asking if they can show you how they do their calculation, analyzing deals etc.. 

@Brian EllwoodI’m looking at getting into the off market arena and pursuing a hardcore marketing campaign.

What I have to say comes from many years of hard core live and learn lessons.
