With a budget of $300K-$400K, you could potentially find single-family homes or small multi-units in those areas.I'd recommend researching rental demand near universities like Duke or NC State or even checking out neighborhoods with strong job growth near tech hubs.

. $150 cash flow on any rental especially a triplex is dangerzone imo. 1 month of vacancy of 1 unit could destroy a years worth of financial gains.  

This burnout led to me selling off my rentals, dissolving my business with family, and having my mother take over managing her own units.

I have two duplex units and am subdividing into townhomes for higher market value.

He was pay ed to install a AC unit in my home and disappeared  he refuse to answer the phone calls texted massages he stole my money and won't respond 

My partner and I have a couple units we manage as well in Washington DC.

I would be open to a 3-4 unit, but my ideal sized property would be 10-20 units."

The units are ready, but due a personal situation I only want one.

The only caveat to that is if you have the ability to turn it into separate units I.E. having a 2/1 and 1/1 instead of a 3/2. 

That is until a roof or an hvac unit fails.
