Purchasing first quadplex.. Advise or suggestions?

[Jay De Jesus]

Hello BP! I'm looking to purchase a quadplex (house hack) and the numbers seem to make sense. The issue or concern I'm having is, several years ago (approx 7) there was grown movement , (possible sinkhole) but current owners sued insurance after patchy work. Lawsuit was won and the job was corrected including any structure etc. They've had no issues since. The quadplex has been well kept, only one apt needs to be renovated but that would be he one I'd take. The other 3 have leases in place. The property appraisers website shows 'functional obsolescence' because of this of course... My hesitation or concern is the obvious.. Has anyone had a similar experience , or could shed some advise it would be greatly appreciated. Thanks
