Life won't end if something goes astray, and there's plenty of education out there to help you mitigate risks as you get going.

After college I worked as a construction estimator for a high-rise developer in Toronto, and currently VP of a civil general contractor in Sarnia, ON.We cashed out of the city life a number of years ago and split the proceeds to by our own home and our first rental property. 

Success is being able to spend your life in your own way.

I've decided to transition out of the 9-5 cubicle life and begin investing in real estate again, SFH and multi is what i'm mostly interested in.  

Is there an ethical way to demand payment or can you chalk up the loss rent on insurance claim?

And if you have an attorney, he should have caught the omission and maybe you can go after his E&O insurance.

Apparently there is what's called the master insurance policy that is supposed to be put into effect first before any secondary or personal insurance can be used.

Insurance agents would be good.

Chase bank recently requested I add this into the listing agreement (LA) I have with the seller:  "SELLER MAY CANCEL THIS AGREEMENT PRIOR TO THE ENDING DATE OF THE LISTING PERIOD WITHOUT ADVANCE NOTICE TO THE BROKER, AND WITHOUT PAYMENT OF A COMMISSION OR ANY OTHER CONSIDERATION IF THE PROPERTY IS CONVEYED TO THE MORTGAGE INSURER OR THE MORTGAGE HOLDER.

Our total mortgage payment is $540/month (tax/insurance) and receive $900 rent.
