We understand that real-estate is a US situs asset so it is subject to US gift tax.

This is my first property purchase and I am nervous about trusting this seller without understanding this more.

You'll see the RE business inside and out and have a good understanding of how things actually work besides the open house cookies and glitz and glam of the paychecks, and surprisingly, that helps more on the RE tests than most of the classes/studying (although all of that is really important too). 

I'm brought to this screen but I need help understanding this.

I've grown up in my market here, the greater Milwaukee area, and I work for a title company so I have a pretty decent understanding of the area overall.

@Roy N.I don't have anyone local helping me out yet because I am still getting familiar and comfortable with analyzing deals and understanding the financing.

I have raised my credit score over 150 in the past year after I took a course on understanding the credit system.

I would suggest digging a bit deeper into the deal to understand it.  

All of the numbers I was using were "lender estimates" which I understand generally aim for erring higher rather than lower.

I understand the circumstances and why title insurance companies are hesitant to provide insurance, but was hoping for a few examples of title insurance companies that would work with you despite the lack of a quiet title.
