some ideas:- yes you could put more money down upfront, even though it's not ideal.- Look for off-market deals that are much cheaper,  using hard money and then refinancing with a rental loan.- Find properties where the owner will finance most of it, so you only need a smaller loan with the higher interest for the down payment.- Take over a property where you can continue the seller’s lower interest payments.- Another thought to give why would you want to do a rental at all, I mean those terms are horrible. why not buy something else with a better return on invest?
