If you're simply seeking leverage for additional properties you can tap banks and hard money/private money lenders.

You minimize your risk of being over leveraged, and barely making ends meet with the rental income. 

Fast forward, I own a property management company and have my business manage the properties.

Currently I’m new as far as leveraging what I have and moving forward from finding potential great deals to closing deals with creative financing.

This was taken care of promptly by a professional remediation company chosen by the insurance company.

Anyone have suggestions of companies they’ve succeeded with?

Yes, I've seen it change in the last couple of years, I had a lender that is a veteran credit union that used to offer them and they stopped.I am W2 employed and have a company on the side for real estate mainly short term rental.

Just hire an insurance broker that can shop the many options for you and will not be partial to any one company. 

I work for the largest property management company in Central Ohio and can attest to the rental growth over the several years.

I work full time at a local Chip( hint people think i work at Stadium) company as an Telecom engineer for last  20 years and still love the work i do and hopefully they don't fire me.
