How much is a contract for deed at zero risk worth?

[Daniel Lochen]

A family friend is selling their storage units that produces an income of $4800 with 2 acres of raw land.

Numbers:

Asking price is $750000

Taxes = $460/mo

Insurance = $140/mo

Income = $4800

Scenario:

Family friend is willing to do a contract where I would technically be an employee and trade my time for shares of the storage LLC. So there would be no down payment needed and essentially no risk. The only issue is that the numbers show the property breaking even at $500k and their asking for $750k.

Is zero risk and potential room to grow worth $250k?
