And we didn't just slow down the cash burn, we stopped it :) Looking at all their income and expenses, they will be cash flow positive annually. 

This is what I have a hard Time understanding and I’m knew so please help me be realistic.It’s seems reasonable to factor in 40% expenses (10% maintenance/ repairs, 10% capex, 10% vancancy, 10% property manager).

Sell Price 700,000 Down Payment 125,000 Loan Amount 575,000 Rate 4.50% Term 360 Monthly Debt Service 2,913 Annual Debt Service 34,961   NOI 46,117 Annual PreTax Cash Flow 11,156 Monthly PreTax Cash Flow 930   GRM 1.10% CAP Rate 6.59% DSCR 1.32 Cash on Cash ROI 8.92%My original plan was to live in one of the units to get a good residential loan (I'm a first time homebuyer) but that would put a $1450 dent in cash flow, making me go negative, so I'm not sure yet until I see the diff between a commercial loan and a residential loan cost.

The townhouse, also a duplex, has way more maintenance, more wear and tear due to children and roommates.  

We can help each other in an informal setting on lessons learned or items such as the following to name a few:- Tenants not paying rent on time or at all- Tenant screening- Contractor suggestions for upgrade/remodel- Upgrades to increase rents- Leasing- Maintenance issues- Other...If you are at all interested please let me know so I can try to put something together, if not, no worries and have a wonderful day!

If you pay the credit card debt the opportunity cost is not having the money for a potential flip.Another thing to consider is APR (annual percentage rate) from credit cards as the name suggests is on yearly basis, while cash on cash for flips is based on the project timeline (contract to close).17% of 12K is only ~2k.  

Ask the manager to explain their process for dealing with maintenance or problem tenants.

Also a list of questions to ask about their former lease, and outstanding maintenance needs would be very useful.

Surely you've already learned how to do maintenance.

You will have maintenance.
