Combine Redfin, Zillow, and Trulia you can piece together some pretty accurate comps and gather a lot neighborhood information.

I would like to get these numbers as accurate as possible before making any offers. 

You'll get what you pay for.Remember diminishing returns applies to accounting, your best system will be that that accurately records your financial transactions in a consistent manner which is easily managed and understood by the reader.

For that reason it is not accurate to say that if you are only paying $51 of a $170 lease per month.

Taxes were pulled off state website and confirmed by seller so they should be accurate.  

Census Bureau so it's about as accurate as you'll get.

I feel like I read all the time about people that "gather other investors" to help come up with a down payment or private money helps them to put a down payment on a property.

Does this look like an accurate analysis or am I using inflated numbers?

@Crystal Smith - yes your points are all spot on - i struggle with accurately gauging whether i think i will for sure cashflow more in a re-sell scenario vs. the cashflow on a re-fi vs. breaking even on either scenario.as far as house hacking, i listened to the BP podcast w/ Brandon Hall and visited the 1031 forum here and as far as I can tell, i can house hack and my tax consequence is pro rata in relation to the portion i occupy. 

@Krisdeon Slack, I am analyzing HMLs right now and agree completely and am still trying to wade through all the fees/costs to get an accurate comparison.
