I figured most people will be preparing and worrying about the upcoming storm. 

We make roughly 120k/year combined.

Figure out what you need to do first.

@Charlie Vess that’s what I figured would be the issue.

Some people are just rough on everything.

I am trying to figure out how one would tie a new roof into this as the starting point is~ 8 foot. and would be obviously less at the other end. 

For example, there might be a 5% premium in your area because historic sale figures support the fact that your neighborhood sells for 5% more than comparable homes in other neighborhoods.

-make sure you have your numbers down (when evaluating cash flow and be super conservative) 
-nail down location and figure out if you want to do buy and hold/ flip / etc. multi family vs single family etcGood luck!!!

Previously, to see if a deal was any good, I just let my financial planner figure it out because I thought it was all too complicated. 

Another way to get rough estimates on such repairs is HomeWyse.com, but as with the book, these costs are general and are only to be used as a guide.
