I am attracted to the BRRRR model -- it seems like an intelligent way to methodically build a good-sized portfolio by reinvesting my original equity over and over, but I also acknowledge that there's a lot to learn. 

I think anything is possible if you choose the right methods.

I've had the "I can't afford Hoboken/JC/Edgewater/Weehawken" conversation more times than I can count in the last 3 months, and natural gentrification in this instance will only lead inland.  

The issue is that you have other identification abilities and are not restricted to the three-day method for some reason.

When analyzing a potential deal, what methods do you use for integrating this expected difference in repair/turnover cost into your analysis of the deal?

When you think about a retail buyer, those that could afford/qualify for a mortgage on a $125k house of this nature are probably more inclined to rent for another year or two and step up to a $140k-$200k house where you are getting stabilized neighborhood, not fringe and much more house. 

@Donna I have 2 methods. 1 I went through local classified ads and looked up keywords like we buy houses,sell house fast,I buy houses etc..

But I can see from the nature of the question how you might have gotten that impression. 

great to hear, various marketing methods yielding results

Depending on the nature and degree of the repairs the tenant may have claim to an equitable interest in the property which would make things messy and complicated in the event you need to evict.
