She does property management in Toledo and owns Flippin Crazy club and she buys and flips homes all over Ohio and Florida. 

When proposing a deal to potential investors, how many investors is ideal to say fund a $500,000 duplex intended for buy and hold? 

With its proximity to NYC, numerous public transportation options, and overall vibe and attraction, it is no wonder why the popularity has been reflected in the buy-and-hold rental market.

Also do you know what you are buying?

I would much rather not buy anything less than a 2 bdr, but i'm also seeing  1 bdr condos for about the same price but in nicer areas.    

You could deploy that money elsewhere and buy a few  smaller (or at least less expensive) homes in a friendlier market and come out way ahead unless you are content with just waiting for the market to appreciate.  

MY SUGGESTION: invest in yourself by buying hard copy books and training on the foundation topics you wish to develop skills (RE legal, title, escrow, financing, notes, etc.).

@Adam ShaIf you can buy a home for cheaper than rent then that is a red flag.

Buy and hold notes (performing and non performing)3.

I told them my buy box multiple times and would still get "leads" that didn't even fit my criteria.
