Buying and selling homes on owner financing

[Willie Morales]

Hello BP 

Confused and really dazed. 

Wanted to know about owner financing, last year I paid cash for a property ( Pennsylvania), and re-sold it on payments, (I'm the bank). 

Here's the problem, I'm looking to buy(upstate NY)  on owner financing and re-sell using owner financing,  A New York City Lawyer told me that I can't do that, I must first buy it outright, then I can sell It on owner financing can't have two mtg's on a property, Is that a New York or National law? did I miss something ?  Please advise....Thank you.
