Has anyone closed a subject to deal in ny?

Hi everyone! 
We have a very motivated seller who reached out to us. They just purchased their home 6 months ago for 275. The currently owe 268. They want to sell their home because they lost their jobs are are moving out of state. If they were to list on the market they would have to go to closing with cash. We offered them to take payment subject to their existing loan. They are all in and ready to move forward. Once we take over payments we plan to do a rent to own contract with a tenant where they buy the property in 3 years. I hear a lot of hesitancy and push back on subject to deals from sellers attornies in NYS. Our plan is to have our attorney write up the contract and then have the seller use our attorney to close as well. Does anyone in NY have experience on successful subject to deals or any feed back? 

Thank you!
