I would Use one of the online tenant screening companies for their rental applications.

I think it also depends on how well the previous owner screened the current tenants that you would inherit with the property too.

I screen well though.

I would just screen them like anyone else.

Do your due diligence, make sure the numbers are good, draft a solid lease, train your tenants and screen new tenants thoroughly.I also recommend getting an inspection on the property and find an inspector who is willing to do a fourplex, it may be a bit more expensive thanks a single family, but I have found it is worth it!

My problem was I did not screen properly. 

You can do your best to budget, plan, screen tenants etc, but sometimes stuff happens.

I'm reading the book managing rental properties. where do I go to print the different types of forms about tenant screening.

Just screen well and inspect quarterly or bi-annual at minimum.Most of my tenant problems (such as late rent) are for the non-S8 tenants due to breakup or job loss - which are not often issues for Section 8 Tenants.

A few thoughts:Go over the contract IN DETAIL  with EACH resident - after screening each one as you would anyone else (income qualifications vary).All students are required to have a qualified co-signer: it protects your interests and gives a layer of accountability that helps in many ways -so you don’t have to use it.
