No exceptions.

I have seen very few variances or exceptions made by Fannie/Freddie.

Exceptions can be made to make each of these DTI's be higher or lower but those are the general numbers.To calculate DTI not only do we take all the debts included on an individual's credit but the new house payment as well.  

I am about to get my Real Estate license except I don't know how that is going to effect the loan origination since I own the properties I'm trying to finance.

When you do so you can make investments inside of the IRA to acquire real estate or any other type of alternative investments (the only exception would be collectibles and life insurance contacts).

All of these are Buy and Hold with the exception of 1 SFR we bought to rehab and flip. 

@Brian Foster The thing people from outside TX (except Alaska) have to worry about is the higher property taxes that make up for the lack of state income tax.

Tenants are paying all of the utilities except for water which is $1,920/year and the annually tax on this property is $12,500 which was included in the owners expense.I don't believe I should cut my net amount in half.

Was wondering what other features investors currently look for in turnkey investments except for the standard returns? 

Ask for an exception or talk to another lender.
