One of the best courses I EVER took was a course called "Tax Factors in Business Decisions" during my MBA.  

So now our numbers look kind of like this: P&I Payment $11,552, Management 8% $1,632, Vacancy Factor 10% $2040, Insurance $1,100, Repair and CapX 10% $2040, Taxes 1.25%=$2,500.

The return you should expect is dependent on lots of factors, but it can be double digit.  

If deceased, there are a number of factors that must be established.

@Matt Huber I think some of what you're seeing has to do with some different factors.  

Once you factor those into the equation, cash flow isn't as important as you probably thought it was.

You would need to factor in repairs and CapEx though. 

Depending on a couple factors, you can certainly get better terms than 14/4.  

Deciding factor will likely be cash flow. 

Will or no will, high value or low value, multiple heirs or a single child, mortgages or no debts, all these things will be factors in determining the complexity of the case.Since you'll need to know the next of kin (either directly or obtained from death certificate) you'll also need to think through what you'd say to someone who just lost a close relative.
