If you can just make sure you are buying right, everything else falls into place eventually.There are markets that perform better than others, but unless you are holding long-term or building rentals, you shouldn't really care too much since flipping is all about buying at the right price for that market:

I've been watching Chad Carson's videos and his approach of accumulating more properties than you need, then start using that income to pay off mortgages and cull the lower performing properties makes sense to me. 

@Jay Hinrichs @Patrick DesjardinsWe rep and warrant all notes (both re-performing and non-performing) to be a valid lien and to be in the lien position as disclosed at the time of purchase.Our current performance warranty on re-performing notes is as follows:"In the event that a re-performing note becomes delinquent, or enters non-performing status, PPR’s Loss Mitigation Department will notify the note investor within 30-60 days and then attempt to address and correct the payment issue prior to the loan becoming 120 days past due.

As a "retired" public accountant and tax consultant I perform a lot of detailed ROI analysis for my clients. 

Tough to stay disciplined as "Past performance is no guarantee of future results". 

Are there other notes you feel perform better than these?

There is a potential scenario where an outside rescue fund (marketed as preferred equity to new investors) could come into play in many of the projects that appear to be performing especially if they have been paying the pref (via a reserve account stockpiled by over raising funds in the beginning).

Again, these are normally in the lower tier  neighborhoods that rarely perform on resale as their appraisal may suggest.

@Kyle Carter we manage around 700 doors, with 92 of them being S8.When S8 applicants are properly screened, they can statistically perform a decent amount better than cash-tenants.

The investor in me has to be wiser about the decision and not worry about sentiment, look to reinvest in something else that will perform better for my family's future.
