I see the point in keeping the liquidity to be able to jump on another deal.  

At that point, you'd be offering your buyers a deal that is not available on MLS. 

It’s not worth the time to deal with it.

Here is an actual deal that I lent on.

This is a great feature for working on a big team like yours because you could have all 14 people on a shared Monday board collaborating on different deals/leads.

You can absolutely make rhe time limit what ever buyer and seller are comfortable with.If your trying to convince a seller to give you seller financing while you flip the house a shorter time may be more convincing than a longer one.You could also offer some of the profits from the flip to help seal the deal.

I would say #1 and #2 are not your first and second priorities.The first priority must be answering "Is this a good deal?". 

I want to start learning, so i thought underwriting deals would be a great first start.

They would need to deal with each other as neighbors or call the police if a local noise ordinance was being violated.

Don't get stuck on analysis paralysis though when you have agents ready to find you deals in Memphis, TN.
