When a deal looks almost too good to be true?

[Johnny Kula]

So the multi-fam property is already positive on NOI. Was recently rehabbed. Has long term tenants that want to stay. Price is about or slightly under market. The downfall... not a great area of town and no parking. I did a search on the deed site, looks like owner is behind on taxes but under $1k. I can't figure out why someone would sell a cash cow...unless the rehab put them under or maybe other projects hurt them enough to have to sell one to make up? For those seasoned investors, why is a property that makes money and is valued somewhat decent be on the market? I'm going to look tomorrow for any major signs of issues but for those that are experienced, what are your thoughts? Any specifics I should look for or ask about? Almost seems too good to be true but the neighborhood might pay a role... Thanks, Johnny
