They are also referred to as All Inclusive Trust Deeds or Wraparound mortgages. 

For creative financing, I have done subject to, all inclusive trust deed, lease option, owner finance deals, private money deals as well as hard money.

This process will allow me to build up enough capital to begin to think about creating a diversified RE portfolio, inclusive of wealth preservation, flips, and rental properties.  

You might not need some of the information given in an all inclusive package.

Yes, the $91,000 is all-inclusive of the purchase price. 

This isn't inclusive but should give you a good start.

You could use a GC, which will most likely result in a higher, all inclusive bid, but in my experience that can turn the seller off- it's best to get individual bids on each item so you can negotiate those away.

You could do this as a wrap around mortgage or an all inclusive trust deed (either one will violate the due on sale clause). 

I would also include a management expense in your analysis because a) you may not always want to manage the property and b) down the road, when you decide to sell or refinance, the bank and most sellers will determine their NOI inclusive of management expense, so you'll want to ensure that your numbers aren't skewed right off the bat.In terms of when to start leasing, I think it depends on the nature of the building.

That's not a common situation, so it isn't usual to get owner financing.Certainly its neater if the seller own's it free and clear, but creative techniques like AITD (all inclusive trust deed), lease options, and contract for deed are all ways to do "owner financing" even if the owner has a loan.
