Most important is getting a RE knowledgeable CPA who knows to outsource the calculation-intensive work involved in a quality engineering-based cost segregation study.  

So I am kind of stuck with what financing options do I have that should help with this scenario.Any thoughts, connections or suggestions of what loan programs can be availed or how to go about it, would be appreciated.

They have many lender relationships and find the best lender (based on the criteria you match to). 

For context, professionally Stocks and Options is my career course and comfort zone.

Also you will likely have way more options on lenders and loan products.#2.

These options are used to tap into equity, in case that would get funds in a similar time frame as Plastiq advertises. 

You can't seem to justify the current asking price, so how are you going to convince another buyer that it's worth more based on zoning?

I, too, am exploring options in this area.

I saw the potential for a big profit margin based on the current market conditions, and what the house was currently listed for.

I would like to be able to contact a property owner, so that I could present a potential creative financing solution (seller finance, lease options, etc.)
