Direct Mail Response! Now what..

[Collette Petersen]

I received an email back from my direct mail campaign, the owner is interested in selling. Before we got into anything he wants to "verify who I am. And verify that I have the funds to purchase." He is asking if I can send him enough information to do a credit report on me. 

Is this something unusual? He is an older gentleman that might see things differently than me, so I am trying to make him as comfortable as possible in this process.

Thanks,
