50% offer is too low?

[John Lee]

I'm look at a house that needed total rehab. Asking price $95k, ARV $120k, max arv $150k. The house is only on the market for a week, I want to come in with $45k offer, my realtor said it's too low and their realtor won't even present it. Can I ask my realtor to submit an offer anyway? And come back with 70% offer if they rejected it?
