Little more detail on the type of foundation and around the cost that was quoted.

After six months, you're in the clear and there's a 0% chance anyone will ask such details.

My partner and I are in negotiation for a 6-unit property in NE Ohio, below are details: 4 rented, 2 vacant / average rent $735 (4 rented units $720, 2 vacant $775)Owner pays water, sewer, trash2 br, 1.5 bath, roughly 900 sfGarage with door + extra parking areaRoof in good shape, air and furnace in good shapeRealistic gross all units filled: monthly $4,400 / yearly $53,000We walked through both vacant units, very clean and basic.

They will ask for detailed material and maintenance costs, ARV projections, cost per sq ft... ect...Although that may all sound daunting at first, it is actually a way to refine your skills and make sure the deal is good enough to justify a hard money loan.  

So I've been working on a tool that not only automates this process but also builds the intelligence behind it.The Relevant Information:A summary report will be available for each property for the investor to examine all the gathered fields.Property DetailsOwner InformationTax InformationForeclosure Case InformationDocket EntriesDefendant InformationMortgage PositionLiensViolationsOpen PermitsThe Intelligence:We created an easy to understand analysis that will give experienced and unexperienced investors a “birds eye’s view” of issues on any given listing using Icons, along with detailed explanations.No issues Found:Proceed With Caution:STOP!

You should have all the details of the property. 

Additionally, I would encourage you to offer many of the details that people plug into the BP calculators in your ad/ listing.

Come by tomorrow night if you can, details at the link here: https://www.biggerpockets.com/forums/521/topics/697410-san-jose-meetup-thursday-4-25-19

Are their listings detailed with good quality photos?

Can you provide the details?
