For me I would not buy a property with zero or negative numbers. 

Those that preach no/low down payments are mostly just trying to appeal to the masses who want everything for nothing that will buy their courses.

The early portion of my career was buying turnkey rentals, like the one you described. 

I use American Tenant Screening and will call them tomorrow.

Little background behind the door: It's a MDF cheap one you buy at HD or Lowes. 

For context, I'm based in the SF Bay Area in CA and looking into buying my first OOS rental after house hacking locally for 10 years.

We also have many unique buyer incentives where an investor can get up to a 10% price reduction to come into immediate equity, or get that 10% as a cash back at closing to reduce your down payment and increase your ROI, or buy rates down into the low 4s on 30yr loans to maximize cash flow.

Buying a turn key rental, in an area you know or knew well, with a property manager you've met and trust, in an area that is large enough for you to have other options to find contractors and property managers? 

Congrats on buying your first condo—that’s a big move, especially in a competitive market like NYC.

Keep the current investment and buy another house hack to live in.
