I feel like your strategy is going to be very difficult to pull off. You are looking for newer properties on the MLS that don't need that much work for substantially under market value... and so is everyone else. You are competing with Home owners, Buy and Hold investors & Flippers. Which means you are relying on mostly luck. Especially in a market that has been heating up. Very few people are going to drop their price in under 30 days & if their agents now they are looking to liquidate fast then it is already going to be marketed at a lower price to encourage a multi-offer situation.
Here are some thoughts.
Short sales are still selling at a discount, make a offer on every shortsale that comes up. Maybe one will bite. They can take a long time to accept your offer, which is why it is best to get a lot of them going at the same time.
Auctions properties are pretty good since your usually only bidding against other investors. There is usually a buyers premium so be aware of that when you buy
Consider direct marketing to owners. There are several Podcasts and articles written on marketing to motivated sellers. Great option since you are not dealing with a direct market.
Learn to evaluate a deal & search for properties yourself. Then make offers through the listing agent while offering them a double ended commission. This creates motivation on the listing agents part to close your deal. This wont work for deep discounts, but if you find a killer deal on the MLS is might work. I have yet to find a reason to work with the a buyers agent. They just slow you down and direct you towards deals that might not be the best in a attempt to earn a commission. Focus on the motivations of everyone involved and decide how you can use it to you advantage.
