I just come across Tarl's video of explaining his updated house flipping spreadsheet using Google sheets.

Ordinances and codes can be complex and lengthy, I would recommend engaging an architect to assist and give in-depth analysis.  

Watch YouTube videos.

Do what many others from there have done, Ohio market, STOP WATCHING videos, total waste of time. 100s enough, take action :) 

This will bring you to the spreadsheet as well as the video on how to use it.  

I would recommend an unbiased party (not anyone on the agent’s team, maybe an experienced local investor) do a video walk through of a property you’re considering an offer on if you can’t see it in person.

I have written a few articles, and posted a YouTube video about this, but there are some great things about this update!

Two days go by and I wake up to a text message from my tenant of a video of the basement flooding with an active leak at 6:50AM.

And what is the mix of guests (couples, entire families with kids, grandparents, parent visiting college students, hikers/water sports, college football fans) maybe theme it to what people think of when they go there or provide things that would enhance their stay (paddle boards, video games, theater room, kayaks, really cool beds that have slides etc).

John Bianchi has some great free videos that I highly suggest watching that will help you analyze markets.
