Many investors have achieved excellent returns here, making Richmond a great place to build capital for future investments.

Purchased for $200,000 with a same-day resale value of $233,000, the property offered excellent returns.

I've been in tech for over 30 years and in Real Estate for over 20 years, our REI deals are still stressful even with excellent tech, resources and processes. 

My $10k example was admittedly unrealistic.However, by way of further background, @Dustin Heiner wrote an excellent article on this topic on his website masterpassiveincome.com titled "What to Do When A Buyer Backs Out From An Assignment Of Contract".In it he suggests a scenario where the assignee decides not to proceed, perhaps after discovering a big ticket repair item that would cost significantly more than the portion of the assignment fee held in escrow. 

The sponsor has an excellent track record5.

Couple that with an online coupon and you have an excellent deal!

Do I just need to give the excel sheet I created to the real estate agent or so I need to actually have a formal offer written out? 

REI Hub is excellent and inexpensive.

If you don't have the stomach for that, hire an excellent property manager and let them be the bad guy. 

Acquired for $236,000 with a resale value of $280,000 on the same day, the property promised excellent returns.
