Couple things....
Submit strong offers and see what happens- even "off-market" deals are going to have hundreds and hundreds of people who will show interest- the email blast is not going to just you. I've learned that the more and more you get involved in this business, your network will grow and people will eventually reach out to YOU personally when deals become available. My friend who flips in DC rarely looks for deals- he has a huge network of people who call him when deals come across their desk. He's done so many projects that realtors/wholesalers etc have HIM on speed dial
I was originally focused on DC (buy 250-400- ARV 550-650) than realized that most of the homes that came across my Inbox needed major renovation (gut jobs)- and of course competition was very high. This was to large of a task for me to take on given my level of experience. So I changed my budget to 100-200 with an ARV of 250-350 and focused on Baltimore. Outside of the Inner Harbor and a few spots downtown, Baltimore is all unfamiliar territory. I didn't feel comfortable relying on others opinion. So I stepped back and decided to focus on what I know- PG County. It fits my budget, most of the homes just need minor updating/lipstick and the buyer pool is much larger given the "cheap" prices. These types of homes don't require high end renovations and you can get away will builders grade carpet, fixtures etc...
I've also looked at investing out of state but like Baltimore, all unfamiliar territory and a weekend trip won't tell me much- but boy are the deals tempting. I follow a realtor on Twitter that posted a 12 unit multi in St. Louis for 225k in a C/D neighborhood with a $450-$500 rent rate- woohoo
Don't get frustrated and more importantly don't give up!
