1980’s duplex too old for 22 yo investor? Large market surge?

[Noah Worley]

Hey BP fam, question for you more experienced investors. 

In my market I can get a class C/D duplex for 280k-350k 

Context: I own one property now which is my primary, my wife and I will be buying a duplex next year and house hacking it while renting my primary. The bank pre approved us for 450k. 

question: my market was recently flooded with these duplexes for sale all in similar neighborhoods and all in the 1980's. It seems like maybe some large investors are dumping their portfolios? Iv kept an eye on the market for about 3 months now and before this large dump there weren't many duplexes at all.

Is this a cause for concern? Maybe these people know something I don't? Maybe they are just liquidating to buy something bigger? 

Are they liquidating because major capx expenses are coming?

Should I avoid buying something from the 1980's if I plan on holding it 15-20 years? 

If I do avoid these what should be my play? 

looking forward to some conversation, thanks!
