My insurance got involved n November 2017 and said since its a 'Walls In' policy and the HOA are responsible for the issue and the damp inside, the claim ought  to be with the HOA's insurance policy (i also pay for that via dues)An engineers report requested in December and was finally provided to me in February 2018 , and sent to the HOA in  February 2018 with an explanation.After a lot of avoidance and misdirection and wasted time (with the damp increasing) the HOA admitted that their policy was no good and so they need to compensate me direct.

At that time though, the interest rates may have increased to the point where it wouldn't make sense to refi.
