How can I coordinate with insurance and restoration companies from abroad?

You can sell a few to pay off the rest or 1031 them into passive income.Any property you buy today should appreciate about 4.9% p.a. that's been US average (insert a % you believe is right, I believe Milwaukee may actually beat this number) over the next decades and your downpayment is leveraged 4:1, so that in itself produces a lot more equity over decades than you could ever safe up. 

@Dennis Dougherty the other benefit to selling is that your full entitlement automatically gets restored.

It needed love and we were able to do the repairs to get it restored!

This house looks beautiful and I can't wait to see it when it's restored.

am in the cleaning and restoration industry.ozone and chlorine dioxide and many other suggestions here might work but the most important thing is that you have to treat the source for it to work.A professional grade black light could have helped you find the source easier before your contractor painted and installed new flooring.If it is very strong odor  the proper way to do it is find source,treat,clean everything and then chlorine dioxide or ozone.

I flip fire-damaged properties and own a restoration company which specializes in fire damage.

Then move forward with a restoration company or trusted contractor who can help you dry out the place starting tomorrow (or ask your existing contractor for recommendations).

Relocation companies, insurance companies, and damage restoration companies are good options also.

Plumbers come the next day and make a bypass so that heat is restored (400$ service call).
