If this is the house on the link, it’s in a Residential Historic District. There could be some stringent rehab rules which usually equate to more $$ to rehab. You may also be (probably are) dealing with lead paint, possibly even asbestos which requires more $$. It appears to be near the river, so check to see if it’s in a flood plain (which is also more $$ for insurance).
The link is from an article printed in 2017. Has this house been on the market for that long?
no, the nice brick one
At the very least, it looks like it needs a new roof......
