For a personalized answer, do visit with any licensed loan officer(s) to determine mortgage qualification; the down payment amount would depend on the type of loan; as for the rate, keep in mind that they do fluctuate daily. You can begin by checking with the bank you currently do business with, any other bank, credit unions, mortgage brokers, etc.
Hi Mural, you should consult a couple loan officers in your area. Your rate will depend on your qualifications - your credit score, debt-to-income ratio etc. Requirements are different for non-owner occupants. Any loan officer would be happy to answer all your questions, take a look at your situation and advise you of your different options. All the best.
