Multiple units or single unit to hedge against vacancy

[Andrew M.]

I was wondering whether multi unit properties or single unit properties present more vacancy risks.

In one way I could single units safer because you can focus all your attention on the single unit, and because once you have a stable tenant your looking at guaranteed 0% vacancy.

On the other hand I could see multi unit being better because if a tenant walks out you are not necessarily facing 100% vacancies although you are probably likely to spend more time with more than 0% vacancy.

Any thought on this would be appreciated.
