I have about 100k in assets both personal and business I could sell, but part of me thinks that’s extreme and I’ll sell “myself” along the way with all my stuff.  

Are you building for pure investment purposes or are you looking to use some of the space for personal/personal business use?

You are likely overpaying by $5,000.Broker fee of $3,000 and Processing Fees of $2,000 seem out of place...but then again, i never used a broker to get a loan so I am not sure about that.If the broker was able to get you an interest rate or loan product that you wouldn't be able to find on the open market...its high, but likely fair.if you are getting a loan product that you could have gotten by going to a normal bank...seems high and unnecessary. 

It wasn’t a massive deal—our expected assignment fee was $10,000—but when you’re growing a business, every opportunity matters.Everything seemed to be moving smoothly until the title search revealed a major roadblock: the mortgage discharge couldn’t be cleared because the person who needed to sign off was deceased.

Quote from @Gianma Vanzo: My wife and I are HI W2 and business owners.

Hi,I have 200k saved for an investment property, and my wife makes 450k a year in business income from her s corp small business.What are some of the best options for my situation?

We both have busy W2's and don't have the time right now to do more (which I'd love to do at some point).

I didn’t leave lol, but I was speaking in terms of the business in general.

The builder’s risk insurance can also provide coverage for lost rental income or loss because of business interruption.

Here's a https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-report to the IRS website noting specific items that are included in the cost segregation study report. hmm, that website is a 404 error.
