The purchase price should be closer to $165K in order to reach the primary goal.To determine if a property is really a candidate for the BRRRR strategy you need to work it backwards from the ARV.  

Had to call them in order to figure out my account number and request to be setup on auto-pay...seems backwards.

This .90% rule in general works as a backwards math for 75% of gross rental > PITI.Hope that helps walk through the scenario and strategy expectation.

Can I work backwards from a projected rent?

To my way of thinking it's backwards.

Why would you bend over backwards to find a replacement property instead of working to find your tenant a comparable property?

Did I do it backwards and perhaps should have gotten the HELOC first, bought the next property out of it and then used my cash?

those are great gross numbers and of course you need that for that price point as the risk of going back wards is greater.for us  15% of gross is a great day.. 10% is avearge.. anything over 15% is a HOMERUN

As others have noted, the data is backward looking and some of these March numbers are for deals that could have very likely been accepted in 2017. 

From my point of view, that would be going backwards - I am wondering how I will continue financing properties once I get to 10!!
