For me, I’ve been testing a few different methods recently, but I’m always looking for new ideas to take my wholesaling game to the next level. 

It isn't the metric you can talk about on a national scale, but if you keep buying the same product in the same area it is a very easy quick and dirty method to know how you are doing compared to other buys. 

Is there a reason why you are set on a traditional duplex? 

Without rent control i either raise their rent far above market rents so they give me notice (my preferred method) or i simply do not renew their lease.

Figure out which method makes the most sense for you and look at the numbers for at least 10 deals.

Are you sure his method is to defy and violate DF?  

You would only pay taxes on all passive investments in a traditional SDIRA at distribution, unless you have a mortgage, then the portion of the income derived because of the mortgage will be subject to UDFI (unrelated debt finance income) which will trigger UBIT (unrelated business income tax). 

Each method has a cost in both time and money.  

Seems like the new on line marketing methods  Section 8 is the new shinny object..

These lenders often have more flexibility with underwriting and may not require traditional income documentation.
