Cash out refi on 4 Duplex properties - what is the limit of properties I can do a cash out on?

[Maximus Decimus]

I own four duplex properties free and clear and am looking to do a cash our refi for 70% of the current value. I have been researching lenders, however I am getting conflicting statements on the property limit guidelines. A credit union I am talking to said that they insure their loans through freddie mac which only allows 4 investment property loans. However I have seen information online which says that you can now have 10 investment property loans under one name, so I am not sure what is the correct information here. Can someone set the record straight as to how many investment property cash out refis you can have under one persons name (not on a business, but personally under my name). Thanks!
