So...I'm new.  I found a listing on BP with a Repairs Value of $47k.  Does the selling agent come up with this number? It then seems logical to ask the agent,  "can you send me an itemized list of what needs to be don...

Also helps verify that accuracy of my agent's view on Muncie as well. 

How accuracy plays a huge role in the estimate, that even being a couple of feet off drawing the diagram can make the difference between needing interior piers - or a extra exterior pier How about being able to discern what is going to be a rental or flip then tuning the estimate to meet those requirements.Being mindful of quality materials that are not outdated and if all possible avoiding those areas by coming up with alternative locations of support - even if it constitutes less piers.   

This will give you MLS access, credibility, and it will ultimately help you determine ARV's in much more accuracy than Zillow or any other site.

Just reach out to me directly as I also tested out 2 known vacant databases for accuracy.

I disagree, for this reason: When I buy an investment property, I can forecast collected rents, vacancy and costs to a high degree of accuracy over the long term, 5 years or greater.

If you are not buying properties at deep discounts or adding value, you have to be able to estimate your cash flows with some level of accuracy and that includes cap ex.  

These wholesalers are sending you to a turkey shoot, just get close and let it all wash out, bad way to do business, shoot with pinpoint accuracy, target what you know you can move.

Obviously, I can't speak to the accuracy of your numbers (and I'd want to know what is included in your holding costs number) because I don't know your situation but I'm sure you did a pretty good job with that.

- Took the rent rates directly form redfin.com link and monthly insurance $75 (rounded up from $62)- For expenses water/sewer ($100), garbage ($50) these are arbitrary numbers I selected without much research (not the best method for accuracy i know :/ ).
