There must be a reason though, cost, weight, etc. 

Newbies like me tend to jump right in and start with few hours of math analysis :) but you are absolutely right to set target first and strategize @Simon Campbell Thanks for your insights on mortgage.

But you have to target entire zip codes.

@Manny Fernandez What list are you targeting?

the bigger question is who are you targeting?

Target ROI for investors is 100%+ over 5 years (10%+ cashflow & 50%+ capital gains) assuming stable economic vacancy of 10%-12% with 3% rent inflation and 7.5-8% exit cap rate. 

I subscribe to Brian Dean (his videos are entertaining & informative), Neil Patel (consistently posted these 2-5 minute clips & Josh Bachnyski (Canadian who seems to know what he is talking about, must take notes when watching his videos).2) Content, in my opinion, should focus on your target market (distressed homeowners).

I send these on to my sons / partners, who come up with a target price, negotiate with sellers and buyers, etc.I don't think we have a rigid formula for pricing, we just know what our buyers will pay for a certain type of house in a certain condition in a certain area. 

Sure, the risk went up, but the goal of the asset protections should be weighted with the hassle factor, cost, likelihood of losing your assets also, IMO.

If you are good face to face, walk a targeted area and visit properties that are in need of repairs.
