50% rule adjusted for Long Island?

[Tom Weyer]

Is anyone using a buy-and-hold strategy on Long Island, specifically in Suffolk County? I'm trying to get my rental analyses fairly accurate and was wondering if the 50% rule is a good benchmark in Suffolk. Houses are expensive and rents a fairly high, but taxes are also high. 

So does anyone have any thoughts? If you have experience renting on Long Island, let me know if and how you adjust the 50% rule.
