It sounds like this buyer has a properly executed sales contract the Seller is trying to back out of improperly. 

After 4 loans I will likely have to change plans but I would still like to go along with a BRRRR strategy.I currently do not have the money to purchase a home at the moment so I plan to continuously learn over the next year about real estate and my market so I am as prepared to execute my plan as possible.

I am a 34 year old executive assistant for a small scientific instrument company in Boston.

You can wholesale an REO as long as you execute the contract in a LLC entity and then assign 100% of your interest and memebership of the LLC to your cash buyer.

@Shaun WeekesI am a wholesale account executive and I noticed your response to a borrower asking about Non-Qm.

Lenders don't want to execute mortgages on low value properties; that's always going to be an issue.

No, but it doesn't have to be it does have to be a strategy that you're comfortable with and will execute which it sounds like it is. 

Then, bare minimum execute a partnership agreement and open a business checking account. 

Use your experience and your condo for your proof of execution.

Cash--out refinance is at the heart of the BRRR strategy, so tough to try and execute that strategy without additional debt.
