@Michael Ehmann nailed it very well, in my opinion. 

@Peter M. nailed his response dead on if you dont have drainage issues.

A conversation with your insurance carrier will help you nail down the insurance cost for a rental property.If you are comparing your owner-occupied property tax to the lender's estimate, then you also need to know that there are discounts available to owner occupants that you won't get as an investor. 

For this to make sense though, there are some important complexities I'm not yet equipped to navigate such as how the tax credits transfer to new owners, whether appraisers would factor this into the value to preserve mortgage integrity, whether installers have better pricing for investors, etc.  

You can get service the same day by using what is called "nail and mail service." 

If they fail to fit your requirements, you will move on to someone else who can meet your expectations.As long as there is mutual communication, your friendship should be preserved.

Still studying though and will nail down a strategy hopefully within the next few months. 

@Antonio Porta has it nailed from my perspective. 

This is all because we focus on capital preservation.

Andreas nailed it...
