Assuming you own a place and want to rent it out and want to buy a new owner occupied property (and will need to mortgage it and the one you're leaving still has a mortgage on it) the bank will require either proof that the old one is rented, the new one is not going to be the rental (substantial value increase and not in a vacation area) or an increased down payment as DJ stated.
Long story short, if any mortgage other than the one you're trying to get shows up on credit (and it's not a home that you're selling) the bank will make you either pay more or jump through some serious hoops to make sure it's a rental or o/o (which in some cases means higher rates/more down payment/guarantor, etc).
ymmv.
