The listing agent or the listing agent's firm then decides how much of a fee they will offer to other agents as an enticement for them to show the property, and the seller typically has to agree to it on the listing agreement--that's generally referred to as a co-broke fee. 

If they have that, you should be OK in the event one breaks off from the other two - and that level of income wouldn't indicate a co-signer or guarantor is needed (other reasons might exist). 600 credit seems good to me - I get to see much worse :) @Duncan Taylor has given you the language you should have in your lease for ALL tenants, not just roommates.

@Sam Kensinger- thanks   1)  is it possible to  ask a relative that  has  dcent  credit and income  to help you  by  being a  " co signor " /  " co borrower " ?     

The first is your father would likely need to be a co-signer on the mortgage.  

Run his credit, do a background check, and ask for a co-signor if his file indicates that he needs one. 

She agreed and I started the loan process but the it didnt go through because my debt to income ratio is high and need a co borrower but i can’t find ine at that time.

We ended up starting a CO satellite office and all new hires got to pick CA or CO. 

Anyways, at 26 years old, you should be able to open a bank account without your parents as you are no longer a minor and you don't have to legally have them as a co applicant. 

@Tyler DurbinMy layman's opinion is option A.  Co

Let me know if you need to do a co-op deal in Texas.
