Consider that by the time a real estate investment "opportunity" has made its way to you, it has already been passed up by everyone in your local area who actually knows anything about real estate investment. If this thing was going to cashflow with minimal effort on the owner's part, someone more connected than you would have bought it before you ever became aware of it.
Doesn't mean you can't make it work. You'll have to do your own financial analysis with real numbers (do you have the last 3-5 years of financial statements to work from to make projections?). But it does mean that you'll probably have to be willing to put in labor, make changes, or take on risk that no one else who considered purchasing the thing had the appetite for.
You'll need to run the actual numbers with realistic projections to have any idea whether it will work. No one who knows what they're talking about would advise you can "analyze (your) real estate purchase" using just the information you've provided.
