I think it's a bit tricky to just compare your NOI vs Net Worth because other assets should be part of your equation that aren't passive (car value, personal residence, jewelry, boat, plane, etc).

I have several vintage buildings here locally in Berwyn and Cicero, and in both cases I have opted to refinish hard woods in most cases as opposed to installing new floors over the top. 

I’m currently in the jewelry business.

That vintage year there are a ton of know problems to fix versus an 80's, 90's, 2000's vintage etc.Now in your area 1912 might be as new as it gets. 

If you have other assets, cash on deposits, securities, boats, planes, cars, trailer, tons of appraised jewelry, inventory, leases or such, then you can use a UCC to file a lien on those assets.

@Austin Faux agree with @J Scott, I would also talk to a local GC and get a quote for building per sq ft and see if it works in the math. 

Are you a vintage house master?

Over time the maintenance will be higher so the net number isn't too far off.What's the vintage age of these building(s)??

There still are small (< 50 units) '60s vintage properties scattered around that have room with value add but it's a hot market.Portland has higher caps in the suburbs but smaller institutions are there too.
