Most likely one of two issues. (1) You don't have an investment grade deal; or (2) you don't have the relationships yet to assign a contract. 

While I am skeptical of the wholesaling profession's prospects for any but high net worth, large scale real estate operators, I could see the odd agent wholesaling a small handful of deals.

Markets like Cleveland, you only need about $130k for C-Grade duplexes.

On a more enterprise scale, I employ RevMax software as well as a fractional revenue manager who looks at the prices daily on a market level and a comp set level. 

No one can answer that because we don't know what market you are in and what your list price is versus the actual value, as well as the scale of the town.When something hasn't sold in 50 days, it's overpriced.

We have a scale for investors that have more than one property. 

Honestly, upgrading to a commercial-grade stackable setup like Speed Queen or Maytag might be your best bet.

As you get more experience, scaling up to larger properties will open up even more opportunities.

You don’t need them or anyone.Now do you want to scale?  

However, I believe multi family provides the best ROI and is the best way to scale.
