Can't find tenant in San Antonio

[Joseph Weisenbloom]

I have a property in southwest San Antonio near Lackland AFB that my property manager is having trouble getting rented for 4 months. Its a duplex with 1 bedroom units. We have lowered the rent twice and my PM claims they have gotten lots of calls but no applications so far. Whenever I ask him why its not rented yet he says that this is normal for this neighborhood.

The neighborhood isn't a warzone but I would classify it as a C neighborhood. All economic indicators point toward strong rental demand in San Antonio. My research shows vacancy rates around 10% for these types of properties.

My question is this normal for this area for a unit to sit vacant this long? Or is it time to fire my property manager?
