Since the property in question is 'investment' property, the potential of portional owner financing is very real.
The best path to success is having your agent write your proposal FIRST and allow them (owner) to counter.
Such offers have many dimensions of benefit including liquidity in three years that offer you additional benefit or the owner to cash out via a note sale.
You need a good agent.
Best of success.
