I feel location is the real deciding factor of rental demand. I think I really need to stay close to the rail stations. Deepak CM said the same. Location could mean 10% vs 50% vacancy rate.
Dropping your asking price may not work. Bargain hunter tenants might be fine people, but there’s a higher probability of problem people.
The low-rent tenants often don’t have a car. I guess 10 minutes walk is the max. Most won’t use a bike.
Streets need to be relatively clean and safe.
Close to park? not important to most tenants.
