To get any cashflow I think I need to be looking for something around $250K, that doesn't need a lot of up front rehab, to give me enough extra for closing and reserves, and in a submarket that will gross 3000/m.

Expect very low LTVs (we're talking like 40-60% down minimum), much higher rates, and very long close times for out of country financing. 

I'm closing on a house that used to be a single family, but was converted to be a duplex.

@Jay Seville can't speak to a 2/2, but even a well-managed (85%+ occupancy) 600sqft 1/1 with view and close proximity to the beach can hit 57K on the Emerald Coast.

Closing on first STR next week. 

At the end of the day, you'll still need good credit, income (rental income from the property will suffice for DSCR loans), and cash to close, including a downpayment (likely 20%+). 

I have close to 100 doors, thus I will pick up something even if it is barely cash flowing so that my other cash flowing assets can pay down the mortgage reasonably quick.

well 70% of 455ks isnt much more than you currently owe at 283k the 70% of 455k is 318.5k and after closing items you might only net 20-30k tops (new loan minus current 283k - closing items = net proceeds in "hand.").So The question you should be thinking about is what are my closing items and is this enough cash to accomplish my mission/goal?

I point the camera at the door so I can see if the door is closed and who is coming in.4) $5 wall mounted big thermometer I use in the winter that is in view of the camera so I can see what the temp is inside 5) Series of signs I printed (Do Use the Toilet, Make Sure to Lock the Back Door, etc etc)All mobile and I can move from property to property :)

Of course, he wants me to cover any closing costs.
