It should cost you next to nothing to own, if you can change your own oil and tires. If you ever decide it's not enough, or find something else, you have ~$1000 in trade value, you're not gonna loose (so long as the bike runs)
As far as bargaining, check the chain and sprockets, check the fork seals, check the tires, (Expect each of those items to cost ~$200+ to repair, I've walked away from several bikes that needed all three!) assume it'll cost you fresh oil and a filter right away and possibly fresh brake fluid and transfer of rego.
Other then that, stick your hand on the exhaust pipe soon as you see it, make sure he's not warmed it up or prepped it. Cold start it and watch very carefully for any smoke from the head or tail pipe (or anywhere else) and emphasis you're gonna be a minute on the test ride, make sure it's warm and run it through all the gears. Take it back, check for oil leaks on and under the bike. .Check all the lights, indicators and horn while out.
$900 is $900, but you don't want to put $500 into it when you could buy a better bike for 2k that's problem free.
