Quote from @Zach Lemaster: @Sebastian Bennett We do pay significantly for advertising with BP. 

The positives are from the buyers prospective1- the ability to buy a property with little down payment2- the ability to obtain financing at below market rate3 -not needing to qualify for convention/institutional financing4- not having another debt on your PFS5 - not needing to pay points and other fees to obtain a new mortgage The positives for the seller are 1- can possibly sell a property in which they have negative equity without bringing cash to the closing table2 -expand the pool of potential buyers 3 -possibly obtain a higher price/ quicker sale 4 - can utilize a wrap to potentially earn the “differential” on interest rate 5 -May be able to save the Realtors commissionAll this being established, here’s the BIG question:  Can a subject to transaction be done where both parties are reasonably protected?  

Attend in person, bid, if you win you have to pay right then via a cashiers check.

This is where it pays to consult with a real estate attorney.

We are building a place with HELOCs then after it is built we will finance it and pay off our HELOC, at least thats our plan. 

You hired someone to do a service for your benefit , YOU pay . not the seller 

That is what we thought, but are being told we have to pay SS and medicare on this now even though it is "deferred." 

We have taken over LOTS of occupied units with under paying tenants.

It seems more your fault for choosing the "lying" contractors from the tenants point of view, if you ask them to pay up, I'm sure they would.

I also think you have a misunderstanding of amortization when you question why you pay so much interest initially.
