I figure it is more efficient to do it this way than driving around to find a fraction of the number of vacant homes in my area and then send a mailer out that will just get thrown away.

I will receive the appropriate fraction of the annual 18% interest on tax liens in District of Columbia for the period I hold the lien and get my surplus bid back.2.

Using the QRP oans get you the second tier financing options, for example, a Roth IRA can buy real estate on leverage, however, will need a non-recourse loan which is often a fraction high-interest rate and lower LTV.
