I work with a property developer, builder, and manager and we're looking to purchase GP interests in both states. 

Do you have a property in mind that you would like to purchase ? 

In my tests, at least, a service contract like a listing would automatically end, but a purchase contract should be honored by the estate unless the court decides it shouldn’t.

Purchase price: $150,000 Cash invested: $20,000 This property was purchased with a 0% downpayment VA laon.

I am assuming your purchase price is in the 50-75k range.1.

You'll need to provide more info on the current financials of the asset you are hoping to buy to substantiate the loan amount and purchase price.

Can’t be more than four units because I will be purchasing via a VA loan.

You have no capital, no credit, no purchase contract, no experience in analyzing deals, and no special knowledge valuable to investors.  

From there you'll need to determine Debt Service (if it's a financed deal) and Capital Expenses, to then calculate Cash Flow.The Cash-on-Cash Return (CoCR) will just be Cash Flow divided by the All-In Investment (Purchase Price + Renovations + Closing Costs + Wholesale Fee).If you're wholesaling these deals, I recommend you aim to offer your buyers a Cash Flow of no less than $250/mo and a CoCR of 10% or higher.

What was the purchase price??
