Next I would definitely walk the property extremely thoroughly, look for foundation problems, roof, hvac, appliances, every sqft of the property should be inspected. 

The roof is new, and the foundation is in good condition.

In Cleveland they cash flow well and you can build a foundation of knowledge this way and a base you can expand upon in the future if desired. 

We also had our foundation engineered certified (FHA required) Had a scheduled closing with an FHA buyer.

My partners and I have put in time for the research and building our foundations including an investor pitch deck.

You have to have a specific angle on a property or be willing to put up with title or condition problems that nobody else is... or compete with cash-rich guys who buy these things all day.At least I didn't overpay, or even worse, fail to do due diligence and end up with a broken foundation and a jumbo IRS lien!

Then go price an engineer to do your site plan and foundation. 

The house was built in 1890 so it has field stone foundation and we noticed some joists in the cellar like they’ve tried to temporary solve this problem.

Any issues with the  foundation will be a no go for me.

MY SUGGESTION: invest in yourself by buying hard copy books and training on the foundation topics you wish to develop skills (RE legal, title, escrow, financing, notes, etc.).
