@Aaron Ferguson It is definitely possible to use creative financing on a property over $1M. If you are able to get the owner some cash flow they are more likely to accept as well. I recommend listening to The Creative Financing Podcast. That's where I learned everything I know about financing.
The offer you make will depend heavily on the situation. Does the seller need a lot of money up front? How much cash flow do they currently make? Is there enough income from the property to give the seller some cash flow and to give you some cash flow? What is the most important thing for the seller (i.e. price, interest rate, down payment, term)? If the seller does not need all of their money upon sale, doing creative financing could be a great way to help them make more money on their equity.
It's definitely possible that the seller would take $80k down. Depending on the purchase price, that would be around 5% down on the property, which isn't uncommon in creative financing. You won't know unless you try ... "Hey Mr. Seller, I typically purchase properties around 5% down, okay?" If they want more, they'll definitely speak up. If he wants a larger down payment, it may be worth finding a partner.
