Writing a solid lease

[Ryan Kawash]

Hey guys, so I'm in the middle of my first real estate deal, a duplex.  Ran the numbers through the rental calculator multiple times with different variances, the numbers are coming out better then expected.  Anyway, I put in an offer, offered 15k lower of the asking price, they accepted.  The duplex is located in a lower-income area in Orange County, NY.  My question is this, once I get tenants in there, what's the best way to write up a lease, is there a tool that helps with this on biggerpockets?  Or should I have a lawyer do it?  What's the most efficient yet effective way of doing this so my tenant feels safe, and I feel protected as well.
