I used to live in the Indy area so I knew the area but not to a granular level. 

That's too granular for me, and perfection is the enemy of progress.

I don't know of any free data aggregator that will offer you that level of granularity.

It is extremely granular and has proven to be very helpful because it sets clear expectations and puts the guy to work on a specific directive.  

I wonder if granular location of these paid a factor. 

There are so many deals that don't pencil, but the ones that do seem to do well for us.Let's connect if you want to talk more granularly about strategy and market.

You can get granular and have an account for each property within QuickBooks Online.Even if you have just one bank account for rental activities you can set up "Classes" and have each property be a class. 

These are major things like (all estimated include labor + materials):1. roof with heavy granular loss and near end of live (needs replacement) - estimated $9K2. foundation grading needs - estimated $1k3. new HVAC needed - estimated $12k4. wood rot on housing in numerous places + wood trim repair/replacement - estimated $2k5. new water heater needed on 1 side - estimated $3k6. rotted facia and soffet - estimated $3k7. soil grading - estimated $1k8. bad electrical wiring that must be rectified by electrical - estimated $1k9. exterior vent repair - $50010. broken window repairs - $50011. exterior paint - $3kone entire side is not renovated (which is fine - but still alone needs it's only 10-20K worth of work to make marketable like the other side - flooring, paint, appliances, and cabinets)estimated total without renovated duplex side: $36-40Kestimated total WITH renovated duplex side: $56-80Kwhat's making me think twice:lender and agent are close (not unusual)things that the appraiser DID NOT find compared to the home inspector made it a perfect pass for FHA loan.

If you want to be more certain, you can sort in Zillow you can see sold comps right next to what you just picked up, and then get more granular to see similar sq ft., lot size, condition, when it sold, bed/bath etc. 

The vacant property list is available, which includes multiple fields of granular address information.
