I advertised on zillow and used a google voice phone number to manage calls/texts. After a preliminary qualification talk on phone (although all criteria is listed in advertising), I set up a Saturday showing from like 9-12noon. It was essentially set up like an open house (sign in, etc) except I didn't tell them it was an open house. I just gave several candidates a specific 1 hr timeframe to arrive. I only showed one candidate at a time the interior of the single family house. The others waited outside for their turn. No one waiting left before seeing the interior; I suspect seeing other ppl there waiting to see the interior, it planted the seed that this property may not be around for long. As decision-maker, I asked every potential candidate, as I looked them dead in their eyes - how's your credit? (Tenants carry all the utilities in their name). Those that had miserable credit, their eyes could not lie...no need to fill out an app. Several tried to fill out the app right then but I made them leave so I could show to next person. It was an effective process. I was looking for the best candidate not the first qualified.
