I was told if I could show a professional license such as a broker license I might get approved but the best option would be a Private Investigators license, otherwise, they didn't see any other path to approval for me or my company.

Even with a professional inspection you can't predict the future.

This post is directed toward professionals who know real estate in and out.

Also, per the images, a crack develops in the kitchen, on the other side of the house where the wall meets the ceiling. 

Readers are advised to seek professional advice.

I'm really interested in hearing directly from professionals in the field: What are main challenges contractors and developers are dealing with on daily basis while building homes?

They are two young professionals with money, they have extremely high demands, they "know already" because they talked to their "xyz professional buddies already." 

The people appear as guests and will tell their story, then you google that person and you find they are partner in XYZ syndication.Linkedin: Look for anyone that has a headline of "I help business professionals create passive income through real estate".This will get you a lot of sponsors and/or capital raisers for other sponsors.  

Ultimately, if you're not considered a real estate professional, then you can only write off up to a certain amount against your regular income (25k maybe?).   

Aside from disclosures, which I think can sometimes hinder a purchase or a sale, it's a lot harder to play dumb as a seller when you are a licensed professional.
