If there is no lease, they are on a month-to-month or what's called a periodic tenancy.

Dealing in the Toledo area  where properties are still available call me if interested

And don't ever call them cockroaches.

When cash buyers call you, tell them it's sold, but you get new properties all the time.How long from when you actually sign the property under contract do you have to close on it?

I'm seriously thinking about calling the bank and just asking, but is that unwise?

Especially the days when you discover that big capex like a roof being blow off (happened 2 years ago), some tweakers climbed up on the roof and gutted the A/C (did two of those in the last 12 months), an evap cooler leaked for so long that the drywall on the ceiling of the kids bedroom caved in (last year), the hot water heater blew a hose and a major leak went unnoticed for 10 hours flooding the hall, kitchen and living room (dealing with that now), the tenant smelled gas outside, the gas company came and shut off the gas because the underground pipe is corroded AND also discovered that the water heater is not venting properly so it got red tagged (just dealt with that last month) or the time the tenant "invited" a homeless guy over, he moved in, then called his other homeless buddy up and he parked his crappy RV with his entire family living in it in the driveway.

@Toby Wade I can manage it for you. give me a call anytime. if you haven't done so already.

We're in the process of suing the tenant for the back rent and damage to the unit and I'm guessing she called the city to report the violations to claim unsafe living conditions or something.

I'm a RE agent, so look me up and feel free to give me a call. 

Because of that I always seek to talk to as many people who call themselves wholesalers.
