How can I solve a seller's problems if I'm using conventional mortgage?

[Christopher R.]

Hi. From what I've been hearing and reading, direct mailing to motivated sellers work because I'm "solving their problems". This means I can help them by buying cash, closing fast, etc.

In YellowLetters.com, a lot of their pre-made postcards even have the word "CASH" displayed very prominently.

But it seems to me that I'm less useful to a motivated seller if I'm using conventional mortgage because I'm not able to close in a couple of weeks and I won't be able to pay them cash, I need to have the property inspected, etc.

But since I don't have any investment properties yet, I could use conventional mortgages for my first 8 or so properties. With the interest from conventional mortgage being lower than other loan sources, it seems like a no brainer to use it for my first deals. 

But this leads me to the question: Am I not as "useful" to a motivated seller because I'll go through a conventional mortgage instead of offering them "cash"?
