Agree with @Corby Goade, @Russell Brazil and @Joe Villeneuve . Throwing out dozens and dozens of offers appears to me a waste of time. When investors come to me with that strategy, I thank them for their time and suggest they go to some other agent who is an order taker and not a consultant.
Much depends upon your individual market but a good agent knows how to win deals and what will work. Most markets around the country are struggling with low inventory. There is no way 99% of those sellers will accept a 70% LTV etc type offer especially when they are new on the market.
So you say why not throw out 100 offers to find that one who will accept? Because while you are wasting time - and it does take time to write, distribute and respond to offers - the smart agent has focused on that one that will work and it will be gone by the time you get to it.
Scour listings on the MLS. Look at dozens or hundreds of homes. Look at comments, time on market, ARVs, etc and narrow it down to the few that have a chance for success and attack those.
I list quite a few estate homes . A healthy percentage of those are, well, to put it kindly, outdated and in disrepair. If I put a home on the market for $525,000 with an ARV of $600,000 that needs $50,000 of work, that is not, initially, a flip home but one priced to attract an owner occupant looking for sweat equity. Ballpark I would say a flipper, looking for a $25,000 profit would need to buy at a maximum $465,000 - maybe lower.
There is no way I - or the seller - will accept that offer after a week or two on the market. If $525,000 doesn't get a contract, we reduce to $510,000 or so. If that doesn't work, we then go to $495,000 and maybe then the $465,000 gets attention.
But really why waste time and energy submitting $465,000 on a newly listed $525,000? But I get those offers all the time. It wastes my time, the other agents time and the buyer and sellers time as I need to present all offers.
If I was going to go to a casino to gamble (I don't), I could keep putting money into a slot machine and I might hit a big one but will probably go home broke. However, if I worked on learning how to count cards, I could sit at a blackjack table and have pretty good odds of walking away a winner. (Okay, I know multiple decks - probably would get thrown out, etc but you get the point.)
