Looking for advice / leads for a knowledgeable real estate lawyer in North Central WI (Antigo, Wausau, and surrounding areas) that can assist with seller financed deals. 

If your business entity has a history of cash flow you could look at getting a business life of credit is another idea.A creative thought is maybe ask the seller for a concession and have them seller  finance the down payment for you that way you are creating some extra money for them as well as granting them some extra income that they would be losing from the sale of the property.

What you need to do is to market for sellers who have a problem   What you really want is people who are drowning in debt, so that you can take over their debt, along with their house.

@Stephen Renehan @Ola Dantis Yeah that's the thing too, is we don't know WHEN we will find a house in this seller's market!

Simply put, the seller holds the mortgage on these properties.

Generally speaking, for FSBO, can the buyers and sellers just use the standard MLS form for the applicable state, and simply cross out parts of the contract which deal with agency, etc?

I'm eager and motivated to learn, I could get sucked into the forums for hours!  

The mechanics are easy, but you are dealing with distressed sellers and situations. 

Is there a place i can go on this site, to get help with the step by step process of being a whole seller?

Is it rocket science, well no, but the average homeowner/seller is also clueless on those items.
