Something fishy, should I shy away?

[Leandro Zhao]

I saw this multi family in my city for 450k where the market is supper hot (probably the ARV is 450k). Just by looking at the building itself, it looks like it will need a lot of work. If outside is bad inside must be worst.

My realtor said the seller will only let you do a viewing if you have an accepted conditional offer. That's probably why this house is in the market for almost a year.

 My plan is to send a really low offer but my realtor does not think this is even worth it the time. He does not want to get involve into this kind of deal.

Should I shy away? Anybody have done some kind of similar with accepted conditional offer for viewing?
