Tenant Screening Question

[Michael Leo]

Hello,

I'm kind of new to real estate investing and first time posting on bigger pockets! I have been trying to self manage a couple of properties for the last 2 years. Haven't had many issues except I run into things I'm not sure how to handle when looking at prospective tenants. Currently trying to rent a 4 BD/2 BA in Lakewood, OH area.

I have a man and his girlfriend applying with the man's mother. They would also be moving in with his 2 kids. I did a rental application through Zillow Property Manager. The income they reported is enough but the man and his girlfriend both have bad credit (530-545) but the mother has good credit (628). I'm also having trouble figuring out how to confirm rental history because they have been living in their grandmother's house and she passed away recently. She was the rental manager they put down. Just wondering if anyone had any advice on how they might handle this situation? Think I'm going to try to find some other service to at lease find/screen tenants in the future.

Thanks!
