Finding Tenants 101 (Residential)

[Cody Evans]

Hi Ya'll,

I have done some scouring of the forums and blogs on information relating to finding tenants and now want to know current information the general BP communities opinion on this matter. 

Should I always have tenants lined up before buying or closing?

What is the most efficient/effective way to advertise vacancies?

How much should I factor advertising(not vacancy allowance) into my expenses?

Please feel free to add information not related to these questions.
