Vacancy can happen any time, any month and yes, always more difficult in Dec/Jan. However, I know a few MF owners close to you who have vacancies coming up, but with good marketing they are already filled..so 100% occupied (Queen Mary Park).
Central McDougal is a rougher area IMO, saw financials on a building near you and they were at 17% vacancy for all of 2010 (I personally question the management).
My questions:
1. Do you know how they are marketing the property? Have you seen the ads, do you know where they are posted, are there signs up on the property, is there a website for that particular building???
2. Have you called in as a prospective tenant to see what type of response you get? Is the person on the other line uninterested in helping you, do they even know about the building, do they ask the right questions, etc?
3. What quality are the units? Have you seen the units lately, is the maintenance kept up, how is the curb appeal, etc?
I would say vacancy right now isn't uncommon, but 20% isn't acceptable so make sure you have the right marketing, the right marketing plan and the right people answering the phones/showing the units...miss any of these and you increase your vacancy. It might be time to look at your building as well, how does it show in general for your tenant profile.
