As long as you purchase at least as much as your net sale. 

I found a nice established one for sale.

There may be something called a "Due On Sale" clause.Check and see if all tax parcels are included in one mortgage or if they have separate mortgages.You have to have him spell out what he considers to be a "partial seller financing".

I’d simply ask in what situations where the broker and the brokers firm did nothing to facilitate the sale do you think you should get paid a commission?

I often read that one should seek a commissioned sales role because your comp is uncapped and that has served me well. 

After doing what I felt was enough research—even though the sales pitch was a bit pushy—I decided to move forward.Their pamphlet outlined several guarantees and provided additional details.

BUT I have also heard that it could trigger a due on sales clause, bringing the note fully due at any moment.

Let's clarify this real quick,I understand this model wouldn’t work for every property owner, especially those who are looking to sell outright and walk away from the property entirely, and the approach isn’t designed to replace a traditional property sale. 

Purchase price: $55,000 Cash invested: $25,000 Sale price: $119,000 Bought at around $50kFixed up at around $20kSold at $120k What made you interested in investing in this type of deal?

It's still for sale.
