Homes that are occupied?

[Matthew J. T.]

When wholesaling a house that is currently occupied what is the process that is involved? Do you basically put it under contract, and once the end buyer has purchased it how long does the seller have to move out? I read you can even have the end buyer rent it out back to the original seller if they were in some kind of financial distress. I don't know if it's anything that really matters on my end, but figured I would ask. Also how far in advance should you let your seller know you are going to be looking at the property with your partner ( end buyer)?
