I wonder if they'd be as interested in the property if there's a lis pendens on the title, or whether they're doing anything that is bordering on illegal by trying to coerce the seller to not honor the contract?  

@Andres Diego I had to get formal appraisals done on the properties and then I had to submit those along with the purchase agreements to the IRS.

The buyer would potentially provide a down payment (agreed by both parties) and then the seller will hold a promissory note for the difference between the sales price of the property and the down payment provided by the buyer.In essence, the seller then becomes the bank/lender and then must follow all of the same laws that lenders must follow in the event of a default and formal foreclosure proceedings must occur.In regards to the renting of the property.

I mostly invest in mobile homes which are usually on the border Bexar county and drive atleast 30 minutes to find my deals. 

so, besides the formal training in REI i have, i attended 2 of @Brandon Turner's webinars and just bought @JScott's book on flipping( i'm excited),  i'm so ready to dive in with both legs cos i don't want to be a victim of analysis paralysis!!.

@Toby Coons, what you are describing is a Joint Venture Partnership, which should be formalized in legalese writing if you proceed.

I would register a corporation, roll your profits back into the corporation for future investments and avoid the cross border taxes.

Particularly the restricted zone which is land within 50km of the coast or 100km of the borders requires property to be bought through a trust you cannot own it directly.

I wanted to give a formal newbie introduction of myself to Bigger Pockets, and to the Arizona Investors out there.

The mail not returned, I'd send them a more formal letter a month later.
