You need to open a bank account, get an EIN, etc.

I'm going into real estate investment banking after graduation and thought it would be wise to get my hands dirty with a deal in the meantime.

I strongly feel a bank would be cool using an escrow account for verification of funds.

Do two: one using cash purchase and the other using a bank loan with 20% down.

Also how do I make it look like my company still makes money so the bank will lend to me later on?

Also, Solera Bank is (one?)

Well I just spoke to the bank serving the assumable loan and they said they could sign me a waver that the due on sale clause will not trigger as long as you paid.

If a borrower is low on cash reserves, but still needs to show 6-9 months of PITI in the bank, a program that gives you credit for your cash-out funds towards the asset requirement is extremely helpful.

You can get financing for american properties through most of the big 5 banks in Canada. 

But now, you have defeated the reason for doing the  Subject To and have become a lender to someone who probably doesn't qualify for bank financing.
