Hello -Looking to buy a duplex in Albany, NY as an investment property but have little cash. 

@Kevin Hintz It's property dependent, obviously, but last year, I sold one a street back from the beach that they're cash flowing.

You don't want to cash-out refi and then be sitting on cash costing you 7% while you search for a deal.

Are there any other markets that really pop and stand out for cash-flow and easy entrance? 

Duplexes cash flow better, have less risk, AND EASIER TO MANAGE compared to a SFH.  

With substantial equity in your Fort Worth rental, a cash-out refinance could free up funds to purchase additional properties.

You are correct that putting 3.5% down on a fourplex likely won't cash flow after one year.

My underwriting would have this large negative cash flow for 7 years.I would do a thorough underwriting but want to show using quick math the issue so I will use the 50% rule.  

Quote from @Erick Pena: A "good" rental property is one that covers all expenses (mortgage, taxes, insurance, maintenance, property management fees, and any other costs) and still leave a surplus (commonly referred to as cash flow).Calculate cash flow as: Cash Flow = Rental Income − Operating Expenses − DebtThere's much more to it, but that's the basic idea.

Purchase price: $155,000 Cash invested: $60,078 Sale price: $275,000 Fix & Flip property in great neighborhood in Saraland, AL.
