This seems to make sense for all parties involved in 1031 exchanges.

The best part is the value of the property doesn't matter much because it will always come back in 5 to 10 years and probably more so.

There are at minimum two parties: the optionee and the optionor.   

The "seller" here is an agent of the secured party who provides no warranties, claims to know nothing about the subject property and refuses to complete and execute standard title company documents.

You are buying a bed and events venue that will sink or swim based on your ability to self develop local marketing for : weddings, corporate dept getaways, mastermind meetings, anniversaries, birthday parties, religious getaways, sports recruiting events, sales conferences, corporate team building, family reunions, off site tailgate parties,etc.

I am working through a third party company that lists deals and they are requiring that I provide a picture of my ID and that I sign an NDA.

Worse, even if your right in your analysis, that doesn't mean the other party will agree. 

Depends on the State Regulations. 6.Seller SecondsThis is a mortgage issued by the seller to the buyer that is placed in a subordinate or second position to an existing first mortgage from a conventional lender; seller second can be a great incentive to buyers; can help them purchase by putting down less cash-leveraging their assets; second mortgages typically carry a higher interest rate than first mortgages, an advantage for the seller over other investment options; a seller second can open new opportunities for buyers in markets where conventional lenders are tightening their loan to value guidelines and buyers need a way to close the resulting financing gap; lenders who want to limit their exposure may agree to a "Combined Loan to Value" guideline that supports a seller second; seller seconds may help buyers reduce their conventional loan needs below the PMI (private mortgage insurance) level, saving significant dollars per month; seller seconds can also help in larger purchases, reducing the amount buyers would need to borrow conventionally, bringing their remaining loan requirement within reduced rate "jumbo" loan territory; some conventional loans prohibit secondary financing; second loans not disclosed to conventional lenders are illegal.sellers granting a second loan must file a lien on the property. 7.Lease with Option and Lease PurchaseA lease with option to purchase is an agreement that the leasing party can buy (or not buy) the property at lease end for an agreed price; a lease purchase agreement, the leasing party commits to purchasing the property immediately at lease end; the owner agrees to apply a portion of the monthly rent payment toward either the buyer's down payment or closing costs at time of purchase.

There are laws against outside parties interfering with contracts.

The seller offers a split for the buyers agent who come alongside, when the sale is escrowed each party takes their fee.
