If you did NOT mention the Purchase Price you paid, that means you OVERPAID for the domain.
Tell us the Price you paid so we can judge if you made a "great" negotiation or NOT... Iam sure you Overpaid, otherwise you will be Screaming out loud the Bargain price you paid for it, and its Not your case...
Before you paid a lot of money for a domain, first you MUST find REAL ENDUSERS, and SAL does Not have real end users and is Not targeted to a specific Industry, thats why the previous owner decided to sell it.
Now, people made up Fake Endusers like Steak and lobster! WTF!! ahahahahaha! this is BAD Sign, it means, there is No Enduser or a Clear Industry to Market the domain.
Or even Worse, somebody will tell, hey SAL is Crypto related!! ahahahahahaha!!
