My first question is what creative financing strategies have worked well for you?

I am sure there are deals in the hood that can be bought with no money down or creatively. 

If the seller is set on that $600K payout, will they entertain creative financing on the remaining balance?

You don't have to do creative financing necessarily, and don't write off properties just because they are on the MLS.

We have to move, so I’m open to flexible options—whether that’s a creative financing deal, a lease-back, or something else entirely.

I believe it is over priced (originally for sale by owner for $280k,later listed through agent at $360k), but I feel like the seller may be open to a creative financing option.
