There have been some good deals on the MLS but there's a lot of competition.

Because of that, many investors don't spend their time working these lists and when I send mail, I have less competition.  

I live in a very competitive and overpriced market and have spent the last few years focusing on my career as a Structural Engineer educating myself and saving my money for the future. 

The rent should be between $225 and $300 to be competitive in the region.

Reality, it will be a hard sell to have tenants in a C- area paying the existing rent with gas bills on top of that, they aren't that stupid, you'll need to reduce rents to reflect utilities to the competition of comparable rentals.

You reduce your competition drastically by putting in the effort that most would balk at!

Are you suggesting that you should never adjust your numbers, even to compete in a competitive market?

Otoh, flipping right now is strong due to the lack of inventory, but again you face more competition for the same properties.  

What's competitive in your area?

@Michael CampbellIf you're mailing in Philly, it's a competitive market.
