Lowering Tax Exposure While Still Qualifying for Financing?

[AP Horvath]

Question for you smart bears out there -- 

How do folks

a) reduce their tax exposure

while simultaneously

b) continue to qualify for financing for bigger and better deals (as they continue to do deals)? 

For example, my day job is in tech and I pay myself a modest salary and my company (I own it) pays for things like my cars etc etc

I get the basic precepts of a) (expense & depreciate everything allowed etc etc) -- but if you are too successful in that, when it comes time to finance your next deal, doesn't the lender beat you up about not having enough income and subsequently make it harder to qualify for debt for larger deals? 

Would love foranyone who has conquered what seems to be a fundamental paradox to provide their thoughts.
