There. Period! As much as an Orange County, or Internet lender will tell you that they can DO the loan, in Austin, it would be FAR better - for you, anyway - to use a lender in the Austin area, for a home purchase there.
You should find a good Realtor in that area - I can recommend a couple - and ask that Realtor who they recommend. Most of us experienced Realtors have favorite lenders who we will wholeheartedly recommend. That relationship is typically built on a long earned trust. For example, in THIS area, I've been successfully working with my homebuying clients for over 36 years, and one of the lenders I recommend has been right beside me for over 30 years.
Back to using a local lender in Austin, there are too many things that can go wrong in a real estate purchase - it is far best to use not only a good local Realtor, but to use a good local lender, so they will be right on top of the transaction, from start to finish. That's MY opinion, anyway. Good luck, in Texas.
