You need to take a proper application and do a background check.

I am not sure of your DTI ratio's, but you will be required to count the full payment towards your DTI until you have 2 years of landlording experience (reporting on schedule E of tax returns), which could make it hard to continue the process right away without flipping a couple or being patient and getting to the 2 year mark!

Your home office expenses will be reported on Schedule E. 

So what is the proper way to transistion from one tenant to another in a years lease?

. * And not doing the proper research about the market you are buying in.

Then make sure it is properly served (i.e. personal service, substituted service on another person, or "nailing and mailing").Then wait the 3 days to see if the tenant pays. 

Can I do 3-day eviction notice because they didn't maintain the house properly?

@Mindy Jensen I wish I would have listened to your advice about doing the rehab with roommates, especially with setting proper expectations.

I have found a flip deal that I am trying to put together in Florida and I attempted to start a discussion with the R/E agent, but quickly got back the reply of "show me the money." 

If you can demonstrate the mold was not present prior to occupancy and that it is likely caused by their lack of proper ventilation, they should be charged for it.I missed something earlier that is extremely important.
