In my condos, I hold: they are pretty new, with healhy equity already, and solid, with no Special Assessment at the horizon.

Your intent must be to hold for productive investment use. 

Since you're looking to get started without down payment funds, consider exploring options like seller financing, where the seller may finance part of the purchase, or looking for partners who might invest with you.

For an owner-occupied property or investment property?

By giving them this info , we are doing a couple of things - First, giving them solid data that they may not have.

We dealt with rentals, flips, commercial, small apartment complex developments (~10 apartments), sport facilities, and a few government contracts.We are actually very open to different opportunities and investment approaches, but our plan was to start "smaller" with some cash deals in NJ (maybe somewhere in the area between Staten Island and Philadelphia, but staying in NJ), by flipping a few smaller properties and starting to generate some income.

To make sure the investment satisfies your financial objectives, establish your target profit margin.Decide how much money is needed overall for the transaction.

If you ask most small-time NNJ investors today, they are investing for appreciation and are OK with breakeven scenarios on the cash flow side, which is risky even for a stable market like the NYC metro area.

Can you invest them and do better than what you are making now?
