We just want to make sure we have the right information before sending the letter.

It's a 3 bed, 2 1/2 bath in a decent neighborhood, and I submitted an offer 5K over asking price (the market here is brutal and I keep getting beat out), as well as submitted a letter to the seller in hopes of making my offer stand out. 

You did not mention your money status in your initial letter.  

I'm new to wholesaling I sent out my first direct mail letters to houses that I saw while D4D!

Then you have to decide if you are ok with a Real Estate Contract or Note and Deed of Trust.I'd get a letter of intent to the seller.  

Don't the buyers have to submit a loan approval letter with the offer?

I did visit the website and I did send in my info with the quick letter at the bottom.

I feel like I've got the basic idea down about as good as one can without actually doing it.Before I actually get out there and send the letters, there are some specifics I would like to talk to an experienced wholesaler about.  

For example, the folks at YellowLetters.com and Yellow Letters Complete can both pull lead lists for you. 

Simple - - send registered letter to the new location marked ADDRESSEE ONLY.Don't seek shortcuts, you'll only cut off your own nose.
