I am fairly well-versed in construction methods and materials, but short on time and manpower, so-to-speak.  

Best advise talk to title CO explain what you want to accomplish, and have them propose a method they are comfortable with that keeps everything legal. 

Banks are holding stuff back and releasing it methodically to keep from flooding (and crashing) the market.

I am interested in using this method of investing, but how can I manage construction from another state?

But yea I would have been proud of the work if I did what I wanted to do so I will definitely scale back and invest that extra money into a BRRRR property down the road... 

Then we bought our second home did a live in flip or BRRRR strategy whatever you want to call it.

Search here on BP for BRRRR.  

(same thing, different name)I'd like to use this method, as my ultimate goal is to own multi-unit rental properties.

I'm looking at the different delivery methods of real estate classes & was wondering if there is such a thing as those classes on audiobook.

. - I would suggest sticking to the basics as there is a ton of money in any of them - Flip/Wholesale/Landlord - Take one of those and get really good at finding deals that fit one of those methods.
