PM was more about collecting rent than quality tenants.

Are their listings detailed with good quality photos?

Just a suggestion, but if you hire a property manager, they'll take care of all the advertising, tenant screening and application process for you.

What quality control measures do they have in place?

Good screening got rid of the fear. 

If you are good at standing your ground, learning your law, developing processes, application screening, studying the market, and all other tasks involved then it may be worth trying it on your own.

Screens, TV/computer/phone will effect the tired sensation and likely keep you up longer than you wanted.

The sales paperwork said the property had a source of water that met the city drinking water quality standards.

@Caleb Anderson I don’t think a two year lease is too long but I would go any longer - you want to be able to raise the rent on them if taxes increase in your area - have an attorney review your lease and make sure you are taking advantage of your states property code as it relates to landlords - each state is different - we have a lease break provision written into our leases - also a good real estate rental agent in your area can be worth their weight in gold - they will find better tenants (screen them all) and quickly put your house back on the market in instances like this

I am looking for some advice/thoughts from others on the tenant screening/background check for such a situation as I know many people do this.
