New North Jersey Investor.. Need Advice!

[Matthew McConville]

Hi All!  My name is Matt and I'm new the world of real estate investing.  I've been listening to the BP podcasts for the last couple of months now, have read several books including Set For Life and The Book on Real Estate Investing.  I'm from northern NJ and have been looking for a house hack for the last few months and am finding it extremely difficult to find something where the numbers make sense (using BP's rental property calculator).  Has anyone had similar problems?  For those who invest in the area, what percentages do you usually use when determining maintenance, capital expenditures, vacancy rates, etc.  Any input is greatly appreciated!
