Well, Just like many other homes affected by the freeze in our area, every water pipe in our house burst, causing ten's of thousands of dollars in damages.

I just don't know if it is worth it.Is it likely I will recoup any investment to address some of the fundamental issues (raise sagging floors in the lower unit plus addressing issues that will cause in the upper unit when the walls raise 1-2", replace galvanized piping, re-do the poorly done roof) when we look to sell in 10-15 years?

It generally works just fine, but can cause serious issues when it doesn’t.

Cause every day that refinance is pushed back you are losing money on that interest. 

If they do stay though they will be brought to court and will most likely have to pay whatever damages they've caused by staying.Doing some quick research it looks like for North Carolina the notice needs to be given only 7 days before.

I looked at one of the estimators and depending on the condition/upgrades it came out to between $725,000 and $875,000 for a 4000 sq ft 3 family.We have multiple markets for the Dwelling Fire policies and when we change a client from Actual Cash Value (ACV) (depreciated costs) to replacement Cost the limits are what cause the increase. 

I look forward to contributing to this noble cause. 

If the odor is not properly mitigated that will cause ongoing problems.

I pretty much always do $25 - $50/year increases to help keep the home at market rents (rents range from 1100-1600), but it's not so much at a time that it either incites them to move or causes too much stress on the tenant.
