Are you looking to be full time active investor or a more passive role.

Does this person just exercise their option to walk away from the deal because of some contingency?

If they seem like they are kind of beating around the bush, I ask directly if they are wholesalers; or I'll ask what is their role or title in their company.

$600k untaxed is reason enough for me to bite the bullet, but life situations obviously play a big role.

if they help you move the property you would split the profits with them.going through this exercise will also give you feedback on whether or not you really do have a great deal.if you need more help feel free to PM me....

Downside is that you would want to do your own research as this obviously doesn't have advisory services which is why  commissions are so little, if you're looking for a company that has more of an advisory role than you would want to  look for a company more similar to Edward Jones.

This is really a budgeting exercise to understand what I can comfortably afford.  

Call or knock on their door - offer them some options to solve their problem - get a loan - raise $ to pay their taxes - a joint venture or sell their home to you or sell to you with an option to buy back while remaining in their house as a tenant until they can exercise their option to regain ownership of their home - you create a great return by paying their taxes. 

The end buyer often plays an active role in the negotiation.In the education to which I'm connected, Short Sales is a two 8-hour days class.

The tax sale roles are a good place for leads you'll spend only time on.
