However, I'm sure many people have, especially if they have images or floor plans of the houses/other features and lots of data. 

In theory yes, but it does not make sense from a tax planning point.

I currently house hack a duplex that I plan to cash out refi soon to repeat.

They are rentals that are both cash flowing and under lease until next May, at which point I plan to rehab and resale.

Cash Plan to refinance when rates are more favorable How did you add value to the deal?

I avoid this problem by sticking with the my process outlined above.

I'm willing to exchange my home improvement services for the opportunity to learn the process from someone who's already doing it successfully.If you're in Connecticut and interested in sharing your knowledge or have advice for a newcomer like me, please reach out.

Start with calling the planning dept at the city to define the zoning and allowed density 2.

They have started the process with the post office fraud division to hopefully recoup some if not all of their money.

From there you can submit plans/permits, and from there you can begin your rehab.
