Possible (but I doubt easy) if seller takes a 2nd / subordinate position to the bank or is secured by other property you own.

Their ability to recover their money should you default is much lower in this position.

The terms for a 2nd position loan on a rental is 6%, 25 year term,  and 2 points origination fee.  

You could put seller financing on second position and get financing for the first and do a 90% CLTV.I don't think any lender (unless private) will let you put nothing down.

So as @Melanie P. said, any positive cash flow is enough. 

But if your goal is to cashflow positive from the Day 1, you may find it very challenging due to current day interest rates, high cost of construction and the fact you won't have the efficiencies of a seasoned developer building at scale.

Hi BiggerPockets Community,I’m looking for advice on breaking even or generating positive cash flow with my studio condo in Prospect Heights, NYC.

Building a trusted team is key, so starting that process as you actively search for your market will put you in a strong position moving forward.

Your cash flow is positive on paper, but how will that look in reality?

I always love to see the positive attitude - that's half the battle.
