Can you suggest an insurance company and contacts for our rental houses?

It was all really quick, and the time to complete everything happened a lot faster than I expected (which was a good thing).I was worried at first that I had to use all the partners that Rent to Retirement had, but it was really easy for me to shop around for different lenders with different terms and rates, insurance providers, and property management company.

How about the increased home insurance cost for a landlord policy?

An additional benefit of a detailed engineering-based Cost Segregation Study is that it can increase potential insurance premium savings as well as provide support for the property tax appeals process.

Assuming property taxes + insurance added don't go above $1,100 total, you could maybe make this work. 

My partner and I keep an excel spreadsheet of rent, our purchases, utilities, taxes, insurance, and money spent on contractors.

My Insurance Agent has strongly recommended that I put a Construction Agreement in place with my Contractor to shield me from liability, etc. 

However, before you do so you should ensure that your revenue from rental income covers ALL your property expenses in the townhome, including mortgage, taxes, insurance, maintenance/repairs, vacancy, property management, etc...

After a year at staring at insurance data daily, AZ insurance rates are only increasing marginally, while most states are damn near doubling.3.

It's an estimated cash on cash return given current rental rates subtract expenses assuming 7% interest rate, 10% management fee, 5% repairs, 5% capex and other expenses like mortgage, insurance, tax. it's a estimate to tell you what properties to analyze vs ignoreyou can see the are pockets of negative returns as well as pockets of positive return. this is to supplement the data @Devin Conley provided
