Lynda! Welcome to the real estate investor club.
Building good relationships with knowledgeable professionals like Real Estate Agents, Real Estate Lawyers, Property Management companies, Local handymen and contractors, and of course an Independent Insurance Agent. All can be a major benefit to you and your end goals, as long as you keep those goals in sight both when looking in the short term and long term.
One of the reasons that knowing the difference between low risk and high risk properties is for cost of insurance... I have a client whose cheapest house to insure is actually his most expensive property, his most expensive property to insure is about $1500 a year and the home is only worth about $120K and his cheapest house to insure at $520 a year is worth over $500K...
Meaning that where the houses are located, the neighborhoods, and proximity to different variables like emergency response time, local theft/vandalism/arson, violent crimes, and others all play into the cost of your properties insurance... and they also play in what you can expect to rent a property for.
