Is there a website that compares price estimate to rent estimate whether for a specific property or zip code/neighborhood?

Wikipedia defines the neighborhoods of Milwaukee https://en.wikipedia.org/wiki/...Trulia crime map is exceptionally accurate for Milwaukee and I find Redfin Estimate to be good starting point as for some reason, it's much more accurate than other sites. 

Both will be able to point out potential issues, but on the GC can give you an estimate to repair.

I would estimate the sale price in today's market would be circa $85,000.

As an example, I own 16 units (not commercial to be fair) that are c-class, and I've estimated their total value to be just under 3M, and I think it's a fairly conservative estimate.

We're kind of speaking in hypotheticals here and it's always hard because we don't know the property value, purchase price, condition of the shop, cost estimates, etc.Good luck!

Smaller properties they may not have this easily accessible so you might need to do more estimating on income/expenses.

Is there any standard practice to break TCC something like      Site preparation and other works 4-6%,            Service works 14-19%,        Finishing works 20-25%,       Civil works 50-55%,            Consultation charges 3-5% of Total Construction Cost estimations?

Interesting scenario - generally these are situations where an appraiser would use the cost approach when estimating the value of the home or go wider in the parameters for finding comps.
