Help make our offer better!

[Julie Coleman]

My husband and I submitted an offer on a single family house with an accessory dwelling unit studio in outer Los Angeles area. We submitted our offer site unseen (no pictures online-just google streetview). Our offer was 50k over asking the day it posted to MLS. We attended 2 of the 3 open houses. Selling agent said the seller liked us and sounded hopeful. Within hours of the offer deadline, higher offers came in. Seller will likely proceed with counter offers. What options do we have to make our offer more attractive without a higher purchase price? We have 15% down but will need to finance the rest of the loan. Any advice helps!
