Buying Multi purpose commercial property

[Francisco Salvante]

Hey guys, need help! I saw this multi-purpose commercial property,  6000 SF warehouse space, 2500SF for retail office, 3000 SF former restaurant. with 2 - studio and 2 - 1 bedroom apartment on 2nd floor, Selling for 550K, it was bought by the ower in 2018 for 340K. New roof., location not so ideal but high traffic area, selling as is, fixer upper.

Cash or owner financing only - 300K down.

Thinking of making an offer of 450K to pay cash, using HELOC.

Thoughts?

Thank you!
