I am curious as to the pros & cons of the different strategies (Rent to Own, Lease Purchase, Lease Option, straight Owner Finance)?

@Paul Nguyen If you have the money you might consider going straight to rental real estate vs wholesaling first.

Call your local metro housing authority to get a response straight from the source: https://www.rochesterhousing.org/And ask them about VASH...a much better program than section 8. 

Straight lending in IA.  

I suspect this dude makes a good portion of his money out of release fee's.. but there has to be an end date  i would suspect other wise the person doing this would have some major liability.. if someone ever did that to me I would sue their butt straight away.. but then again most wholesalers would never get into contract with me in the first place as I would vette them out and when they could not proof up I would not accept their offer.

Make her show her work though just like the appraiser since if she is shifty she may try to manipulate the value as a ploy to get you to list it with her ... either by understating it's market value and sayibg she could sell it for much more or going straight for an over inflated value if that she could sell it for you for, only to ask for a price reduction after it doesn't sell at that price.

Along with What @Patsy Waldron is saying, make sure you get your documentation straight so that you ARE actually buying the property - it's YOURS. 

You can take the paperwork straight from signing to the title company and have them arrange everything..I like Vena Jones-Cox for learning how to wholesale..

Typically in the MLS there are submission instructions for an offer...and for reos it is almost always through some sort of online system that goes straight to the banks asset manager.

We do all the work ourselves, and I've had good luck using straight or diluted cleaning vinegar to get rid of smells without the fear of bleaching anything you don't want bleached.
