Carrie,
You threw me for a moment at first when I saw that you were in MDR and you were talking about home prices in the $100K-range...Then, you mention the house was in Ohio! LOL...sorry, I digress...
I'm from So Cal but flipping here in Missouri. We are having the same issues as you are - RE Agents don't want to submit our bids because they are so low.
I say screw'em! It's YOUR MONEY. Make offers based on what your calculations show is a good offer. I've had several mentors who said, "if you don't blush when making your first offer, you offered TOO MUCH!". It's advice I've taken to heart.
Tell that agent you'll start writing your own offers if he/she is too lazy to do it. A low offer will only draw a bidding war if there is another buyer. Have your money lined up and be the strongest offer.
Remind your agent that you will be rehabbing the property and re-listing it within a certain time frame (we shoot for 30-60 days for most flips), so they have the potential of getting another listing without having to work for it...at a higher price!
