Blanket Pre-Approval Letter

[Sandhya Gorman]

I mentioned this in my last post, but thought it might get lost in the shuffle, so I am posting under a different subject line.

I am looking at several locations (over 10) for my next rental property.  Can I get a blanket approval letter or do I have to go to a local lender in each area for a pre-approval letter?  Let me know if I can use a national bank or if there is some other way so I don't have to fill out so many applications.  Thanks!
