Thoughts on a deal I came across

[Thomas T Huckabee]

I came across a potential opportunity today and would like anyone's ideas about it. 

I found 4 single units. One is 2 bed and the other 3 are 3 bed. Asking price is 560k. All 4 units are currently leased out and have been steadily leased for the last decade. Homes are in good condition.

Rent on each unit is in the 1150 a month range so about 55k a year income. Taxes and upkeep are about 7k a year. 

From the overview it sounds and looks good but I have A feeling they want to sell for a reason. What do you think?
