Small Balance Multi-Family (Under $1M) is a unique and fast pace market to keep up in so many markets addressed above.

Furthermore, as a high-income earner, I am assuming you have a decent balance sheet and have not overleveraged yourself.

Obviously, you need an income statement, balance sheet, and a cash flow statement.

Primary tasks are to inventory the projects & transactions to the Balance Sheet, track which expenses go to which property so I can keep track of budget, and upon sale, convert all transactions off my Balance Sheet and to the Income Statement so the tax accountant & client can see the profit made. 

@Lance Luvaul I'm guessing your Dad's account has been open for a long time, has a reasonably high credit line, a reasonably low monthly balance relative to that credit line, and no history of late payments.  

1) credit score ….if you can  get  your  rev  debt  spread out so that all card  balances are under  30% of the cards  max limit - this  should help your score improve 2) contact a lender/ loan officer to begin the pre approval process ...you can use whatever   hypothetical you want to and then  adjust  the parameters  as  the file begins  taking shape ...this  process should be easy and free ...definitely get this  completed and in place  before y you begin  property looking

The only way to get a truly accurate number is to get the outstanding balance from the lender, which usually requires cooperation from the owner. 

Also have as many checks and balances as you can.

At time of closing, how do we recoup any outstanding ledger balances from our tenants? 

Balancing your investment portfolio is an ongoing task.
