I feel shady getting properties under contract without funding.

[Trevor Muska]

I have been trying to get my head around the chicken and the egg game. I want to get a property under contract but I'm just starting out and I'm not 100% curtain i will be able to secure funding. Is it shady or immoral to make offers knowing there is a 50% chance or more that i will have to back out? 

How can i make offers without losing out on deposits if i am forced to back out? Or should i secure my funding before making any offers?
