Arson fire homeless!

We were buying my family home I grew up in.  On December 13,2017 a tree fell through our roof.  We were lucky enough to have had home owner's insurance. But four days later, I received a notice in the mail that on December 27,2017 they were going to cancel my policy.  My home did not meet their underwriting insurable standards. 
    So we began the process of rebuilding.  Their value and mine were by far two different numbers. So being framers by trade we set out on the task of doing the work ourselves. We wanted to remodel and make the house better than before, so now was our chance.  We fought many days of rain before we were finally able to get the roof on.  But once we did, there were long days because my husband has a full time job.  Seven days a week.  I broke my ankle and have had to put off surgery because we were on a time schedule.  Our rental property is only paid for through June 30th.  We were only 6 weeks away from completion. We worked til almost dark last Thursday May18,2018. When in the wee hours someone set fire to "Our Dreams".
There is a full blown arson investigation at this time.  A fire fighter was injured battling the blaze.  As I said, No insurance and homeless in about four weeks. 
PLEASE HELP!! Wouldn't Ask if it wasn't necessary.  We are going to find a way to rebuild!
