Why is this important to you? If you can afford $1,000 per month rent, find the best place for that amount. If you want to offer less, you can try but there are no guarantees. It's always possible the landlord will not only decline your terms, but accept another tenant.
If something is over priced, you can try on that one but again no guarantees. Some landlords may accept less from someone they know and trust. Someone who has the skillset to do projects around the house that are needed, thus saving the landlord money. These situations are rare and often develop after the fact. I would just encourage you to focus on choosing a rental within your budget and not try to negotiate everything. Most landlords won't unless it's been vacant a long time.
