I guess without soils report or knowing how deeply the unsuitable soil is, there is no definitive answer.To the OP, vinyl windows with double glass and argon filled is a good option here in SoCal, I have installed a few of them, I only use Milgard on my installs, they offer high quality and high performance ratings.

When I have 11 flips at one time and only a couple guys working you can guess how it turned out. 

Guess I’m a little out of date

My guess: 12/31 2016 - 5.1% & 12/31 2017 - 5.9%. 

Just curious why you are guessing what the cash on cash return will be.

I am not the buy / hold king yet but I have to claim it for it to come true lol Let me guess.... your not a surgeon either, but you stayed at a holiday inn last night.

The estimates given for the repairs are just a guess. 

Not many would be my guess.

I guess you could circle it indefinitely and never risk any attempt to contact any owner or heir. 

I guess I would just check out Amazon or someplace like that for some books that seem relevant and interesting to any specific real estate topics you may find of interest (flipping, rental properties, farmland investing, etc.,)  While these books may not really guide you to getting a license -- so I guess I'm not specifically answering your question -- they will broaden your real estate field of knowledge and should help you in your career in the long run.Other than that -- study, study, study the licensing materials!
