50 % rule in NH

[Bradley Tetu]

Hey all, I'm a new investor in New Hampshire with 1 SF. I am looking to purchase my first multi-family and was curious what others think about the accuracy of the 50% rule in a state with high property taxes. I have seen a few properties that look like extremely good deals based on that rule but am cautious. I like the idea of the rule as a tool to quickly assess whether I should spend any time evaluating a property. What have others experienced?

Thanks 

Brad
