Sale at 397 1st Street #1L

I would like more information on this apartment. I would like to know if excellent credit can bring down the rate percentage. If I pay more than the down payment, will that lower the rate which will lower the monthly payments. Are there pictures of the inside of the house? Can me and my fiancee do an open house with someone? What is the condition of the apartment? When do I have to put down the down payment if I'm interested in purchasing the property? What information is needed to purchase it? Can I put something down to hold the property because we're looking to move next year. Can I king size bed fit in bedroom one? Thanking you n advance for taking your time to read this. Have a great weekend!
