The Lender's requirements for an Investment property are quite different than for your residence:
Normally, they want at least 20% down; you have 50%.
Hypothetically; if you were dealing with a bank, I would deposit the $150 in that bank and tell them that you wanted to put $100,000 down; and keep the rest for taxes, repairs, safety net, etc.
Your down payment isn't tax deductible, but your expenses are (consult your tax person, please).
You may not want to pay off that credit card debt right now, consult first.
you should be okay.
good luck and may God bless
