How can I make sure my offer is attractive?

[Andrew P.]

I am putting in my first offer on a house rehab. The asking price is $250k and the ARV is $520k. Total repairs of around $150k. Holding costs at $20k. There is a lot of competition on this house. I am sure someone is going to make a cash offer that is attractive. Unfortunately I am not in the position to offer cash. I am going to put in an offer around $300k with no concessions but it will have an inspection clause and 7 day due diligence. Any advice? I'm very new to this so if I'm missing something major please let me know. Thanks
