Assume you never met them at the property, and fielded 1 phone call from them.

I have been talking with a few other real estate investors, some suggest to create a website to funnel potential tenants, setting up an automation phone line, and a callers list for screened tenants.currently have two rental properties.

It takes a lot of phone calls and asking around, but you can normally find a local or regional bank that is willing to work with investors on these types of properties.Mike

I currently run a couple of mobile phone stores.
