This reply automatically made me feel more cautious. 

On one year lease since Feb 2012 on autorenew optionI'm requiring tenants to all sign new 12 month lease, non-automatic renawal, to bring rents closer to market averages for local area and cover water and sanitation payments.Unit A - $750Unit B - $925Unit C - $750

From what I can tell, everything looks good, if you overlook the fact that there are currently no tenants in the building.Is this an automatic deal breaker?  

The one that does not involve an automatic email response.

ANY eviction history is an automatic no.

Also if you go to the website it will tell you by state and county what is the marginal error for the Zesitame for example in some areas of TX like Houston I guess the margin for error is around 40% and other areas of Florida is around 8% but I don't relay on any automatic system unless I do my own research.

After your 5 years, the loan either resets the rate automatically based on some target rate (i.e. prime plus x%) or else you "renew" the loan with the lender.But a blanket loan is typically the same thing.

They automatically assumed I would be living in the biggest vacant unit, although I didn't fight them because it didn't impact qualification.

Do you or have you ever accepted a tenant with a previous criminal history or do you automatically move on the the next application?

I can see if you make your payments very month with a check from a different address it might raise a red flag....also if it's units that might automatically trigger an inspection or follow up.
