When renting a duplex, what have been some of the best way you have found tenants & what is your process to screen them? 

When your googling how to get blood out of hardwood, ok than talk to me about a "tenant nightmare".... 

Factor these potential costs into your decision-making process.Prevent Future Issues:To avoid similar issues in the future, make sure to thoroughly screen tenants and emphasize the no-smoking policy during the leasing process.

You'll find more people on regular long-term rental sites than you would on anything designed for MTR, which is not even a term people are familiar with.If you are renting longer than 30 days, you should screen, collect a security deposit, use a written lease agreement, and follow the landlord-tenant laws for long-term rentals.

The people activity looking for a place to rent is constantly changing.There are FB groups where people post they are looking for a place but you would still have to screen them.Section 8 offices might have a list of people with active vouchers.

We’ve also asked them to keep the screen door unlocked so that we can use the key to enter if they are not home.Tenant is active duty military living with his girlfriend.

You could install a security screen door...

4) Your screening criteria for approval?

So I pull up some neighboring comps, hoping that if I add the 5 comps to MM, that screen will no longer pop up and then I can then turn off the toggle switch. 

Otherwise you are DIY running a rooming house and its alot of work screening and managing the 2am fights, tenants leaving their trash in the kitchen iratating the other tenants.Its all doable, just the actual amount of hands on is more then you might think, even if padsplit is in your area and is willing to take your house into their system.
